CERTIFICATION IMPACT ANALYSIS:UL/IEC 60950-1, SECOND EDITION -Safety of Information Technology EquipmentTechnical Editor: Thomas M. BurkePrincipal Engineer – ITE/HT Business SectorUnderwriters Laboratories Inc.This analysis is intended to identify and analyze the impact of notable differences between the latest versions of the UL and IEC Standards for Safety of Information Technology Equipment (ITE) and their predecessors. In particular, IEC 60950-1 Second Edition and UL 60950-1 Second Edition are being analyzed and compared to their predecessors, IEC 60950-1 First Edition and UL 60950-1 First Edition, respectively.This analysis will permit persons already familiar with IEC 60950-1 and UL 60950-1 to become familiar with the impact on ITE of the latest IEC and UL ITE Safety Standards. Other select observations are included that may be of interest to the reader. This analysis may be updated periodically as additional information on the application of the new Standards becomes known.See informative Annex BB (Changes in Second Edition) of IEC 60950-1 for additional information on changes associated with IEC 60950-1, Second Edition.BackgroundIEC 60950-1 is the International Standard for Safety of Information Technology Equipment. It encompasses under its scope information technology equipment, communications equipment, office appliances and multi-media equipment for use in the home, office, business, school, computer room (data center) and similar locations.The latest version of IEC 60950-1, its Second Edition, was published in December 2005. It supersedes its predecessor, IEC 60950-1, First Edition, originally published in 2001.IEC 60950-1 was developed by IEC Technical Committee (TC) 108 (previously TC74), MT2: Safety and Energy Efficiency of Information Technology Equipment. IEC TC 108 MT2 also developed/maintains IEC 60950-21, Information technology equipment – Safety – Part 21: Remote power feeding; IEC 60950-22, Safety of Information Technology Equipment – Part 22: Equipment Installed Outdoors; IEC 60950-23, Safety of Information Technology Equipment – Part 23: Large Data Storage Equipment; IEC 60990, Methods of Measurement of Touch Current and Protective Conductor Current; IEC TR 62102, Electrical Safety - Classification of Interfaces for Equipment to be Connected to Information Technology and Communications Technology Networks; and IEC 62151, Safety of Equipment Electrically Connected to a Telecommunication Network.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.In the U.S. and Canada the ITE Bi-National Standard (BNS), formally designated CSA C22.2 No. 60950-1/UL 60950-1, Second Edition, is based on the Second Edition of IEC 60950-1, and like its predecessors includes U.S./Canadian National Differences to address National requirements not in the base IEC document. This Standard was published on March 27, 2007.The technical content of the BNS is developed and maintained by the Technical Harmonization Committee (THC), Maintenance Team 2 (MT2), which consists of representation from UL, CSA, and the key U.S. and Canadian IT and communications equipment industry groups.The Effective Dates for formal implementation of UL 60950-x Standards are outlined on the UL website –/global/eng/pages/offerings/industries/hightech/informationtechnology/dates/ .Note - Subsequent to the Second Edition of IEC 60950-1, a First Amendment to the Second Edition has been issued as of December 2009. A separate Certification Impact Analysis will be issued to cover Amendment No. 1.Summary of key changes associated with Revision set dated May 21, 2010Below are the key updates to this Analysis associated with the latest revision. (Additional editorial changes/updates also were incorporated into the document.)• 5.1.2.3: Revised analysis of application of simultaneous multiple connections to anA.C. Mains Supply.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved.

For new/revised requirements that are less onerous than existing requirements, the Impact Statement (Minor, Considerable) will be followed by a (-). No symbol next to a Minor statement indicates that although there could be impact, it is indeterminate whether it will be slightly more or less.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Clause 0 (Principles of Safety) Sub-clause DiscussionImpact0.1General Principles of SafetyNew statement added to General Principles of Safety that dimensioning ofinsulation spacings should take into account possible reductions of spacings by manufacturing tolerances, or deformation by handling,manufacturing, transport and normal use.None. Principle of Safety. The principle already isincorporated into the level of requirements in thisminimum safety standard or is assumed to have been considered by manufacturer based on qualitymanufacturing processes typically associated with the Industry.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Clause 1 (General) Sub-clauseDiscussionImpact1.1.1Equipment Covered by this StandardFor the first time theStandard explicitly covers under its scope ITE components andsubassemblies, such as component switch modepower supplies. Scope states that such components and subassemblies may notcomply with “every aspect of the standard, provided that the complete information technology equipment, incorporating such components andsubassemblies, does comply.”This same consideration is inherent to UL’s Recognized Component Conditions of Acceptability. None. Scope. Generally reflects present practice since ITE components and subassemblies have been investigated to IEC 60950-based standards and theirpredecessors for many years.However, this addition provides justification for allowing more ITEcomponents to be provided with an IECEE CBReport/Certificate associated with IEC 60950-1.The previousrequirements for Acoustic Pressure Limiting have been revised andrelocated. Now, instead of being located in 6.5, they are located in Annex NAD, Acoustic Tests. A reference to therequirements has been added into 1.1.1, which also states that the requirements apply to acoustic outputs atcommunication receivers and similar devices used for voicetelecommunication,regardless of transmission medium (e.g.,telecommunication network, cabledistribution network, wireless network, etc.).Minor (+). Potentially, there could be someimpact on manufacturers of ITE with acousticoutputs and intended for connection totransmission mediums other thantelecommunication (like cable and wireless) since the Standard was not explicit before fortransmission media other than telecommunication networks.However, industrypractice generally has been to design ITE with acoustic outputsassociated with voice communication to the appropriate acoustic requirements, even ifCopyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clauseDiscussionImpactThere have been some other modifications of the actual requirements (mainly reintroducing legacy test methods), although the acoustic limits remain the same. See Annex NAD for more discussion.[Note – For Europe, the Second Edition of EN 60950-1 in its 1.3.Z1 (Exposure to excessive sound pressure) now requires ITE to bedesigned and constructed as to present no danger under normal or faultconditions with regards to protection againstexposure to excessive sound pressures fromheadphones or earphones. It references EN 50332-1 and -1, Sound System Equipment: Headphones and earphones associated with portable audio equipment. The fullimplementation/impact of this requirement isunknown at this time, i.e., range of applicability to ITE.]these other transmission mediums are used, so the true impact likely will be relatively minor. See Annex NAD.1.2.2.1Normal LoadReworked definition of“Normal Load” emphasizing that the definition is used for testing purposes, and ifconditions of actual use can be reasonably expected to exceed those recommended by the manufacturer, the more severe conditions are applicable. None. Definition.Clarification, and generally consistent with present practice.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clauseDiscussionImpactAlso, clarifies definition with respect to ITE intended for non-continuous operation. Associated revisions related to non-continuous operation also made to 1.2.2.2, 1.2.2.3, 1.7.3, 4.5.2 and 5.3.8.None. Definition. Revisions made in other areas of the Standard with respect to ITE intended for non-continuous operation (1.2.2.2, 1.2.2.3, 1.7.3, 4.5.2, 5.3.8) and to align with the reviseddefinition result in a similar level of requirements, but should simplify application. 1.2.2.2Rated Operating TimeClarifies that the Rated Operating Time is the“maximum operating time assigned to the equipment by the manufacturer.” None. Definition.Clarification, and generally consistent with present practice.1.2.2.3Rated Resting TimeNew term/definition for “Rating Resting Time” to complement the existing definition of “RatedOperating Time” and to correlate with reviseddefinition of Normal Load, 1.2.2.1.None. Definition.Clarification, and generally consistent with present practice.1.2.5.3Pluggable EquipmentNew higher level term/ definition above Pluggable Equipment Type A andPluggable Equipment Type B. None. Definition. Editorial.1.2.8.3Mains SupplyNew higher-level term/ definition above AC Mains Supply and DC Mains Supply. None. Definition. Editorial.1.2.9.7RMS Working VoltageNew term/definition for “RMS Working Voltage” to complement existing definitions of WorkingVoltage and Peak Working Voltage.None. Definition.Clarification, and generally consistent with present practice.1.2.10.4Solid InsulationNew term/ definition for“Solid Insulation,” defined as “material that provideselectrical insulation between two opposite surfaces, not along an outer surface.” None. Definition.Clarification, and generally consistent with present practice.1.2.13.15 Cheesecloth New term/definition for “Cheesecloth.”None. Definition. Consistent with present practice.1.2.13.16Wrapping TissueNew term/definition for “Wrapping Tissue.”None. Definition. Consistent with present practice.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clauseDiscussionImpact1.2.13.17Protective Current RatingNew term/definition for“Protective Current Rating,” which is defined as “the rating of an overcurrent protective device that is known or assumed to be in place to protect a circuit.”See 2.6.3.3 for associated requirements.None. Definition. Consistent with present practice.1.4.14Simulated Faults and Abnormal ConditionsNew clarification added that “The failure of Functional Insulation is simulated only when required by 5.3.4 c).”Note - For the FirstAmendment to IEC 60950-1 2nd Edition, revisions have been made to 2.8, Safety Interlocks, to clarify the requirements for such fault testing in safety interlock circuits.Minor (-). Clarification.Attempts to limit the amount of short circuit testing between trace-trace on printed circuits boardsassociated with Functional Insulation and concentrate on component faults, unless the Functional insulation does not comply with 5.3.4 a) or b).However, this change and its reference to 5.3.4 c) points out a current deficiency in the Standard. Basic/Double/ Reinforced insulation are only associated with risk of electric shock, and 5.3.4 c) only mentions risk of fire and risk of electric shock, but other circuits involving‘insulation’ could result in a hazard if compromised (e.g., within a safety interlock system circuit (e.g., printed circuit board) protectingagainst ‘mechanical’ hazards, ‘radiation’ hazards, etc.).1.5.6Capacitors Bridging InsulationComplete rework of 1.5.6 to clarify its intent and practical application, including addition of a table that summarizes IEC 60384-14 capacitor ratings and an informative table that provides examples of the None. Clarification, and generally reflects present practice. When using X & Y capacitors in ITE, revised 1.5.6 should reduce time needed to determine appropriate X & YCopyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clauseDiscussionImpactapplication of capacitors.The First Amendment to IEC 60950-1 2nd Edition, includes revisions correcting some minor errors in the Tables. capacitors for the application.1.5.7Resistors Bridging InsulationComplete rework of 1.5.7 to clarify its intent and practical application to resistors bridging Functional, Basic, Supplementary, Double, or Reinforced Insulation.Single resistors are required to pass a new resistor test, and a group of resistors is required to comply with either the specifiedClearance and CreepageDistance requirements or the new resistor test.The new resistor testing consists of the damp heat test per IEC 60068-2-78, followed by impulse testing per Annex N, Table N.1, depending on the type of circuit involved.Minor (+), if a group of resistors is used, and the Clearances and Creepage Distances are assessed as if each resistor was short-circuited in turn. Generally consistent with present practice.Considerable (+), when the new resistor test is required/ chosen since it is a new test.1.5.9Surge SuppressorsNew sub-clause on Surge Suppressors.For surge suppression devices used in Primary Circuits, these devices are required to be a Voltage Dependent Resistor (VDR) type, like a MOV/Varistor and to be subjected to new requirements in Annex Q,Voltage Dependent Resistors.Also, defines specificrequirements when VDR is bridging Functional, Basic, Supplementary, Double, or Reinforced Insulation.Considerable (+). For the first time the Standard explicitly addresses the general use of surgesuppressors, which likely will have some impact as different practices bydifferent manufacturers, and NCBs will now be driven to be more closely aligned.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clauseDiscussionImpactAn ‘interrupting means’ (e.g., fuse) is required in series with VDR to protect against overvoltage, thermal overload, or burning/bursting in the event of a short-circuit.There are no newrequirements for suchdevices used in Secondary Circuits.Note- A Gas Discharge Tube (GDT) is not included in the definition of a VDR. However, the FirstAmendment to IEC 60950-1 2nd Edition, clarifies thatVDRs & GDTs may be used in series when bridging Basic insulation only.It is noted that 1.5.9continues to need additional work to clarify the intended application of some of the requirements discussed above.1.5.9.2Protection of VDRsSpecifies an "interrupting means" is required in series with VDR to protect against overvoltage, thermaloverload, or burning/bursting in the event of a short-circuit.It is not clear yet was it the intent of IEC TC108 to allow a single device, or require multiple devices to meet this requirement. Considerable (+). WhenVDRs were used in ITE in the past, typically there was not review/analysis of the types of protective devices used to protect the VDRs in case of overvoltage, thermaloverload or burning/bursting.This new requirement should help promote consistency, although there likely will be some impact as different practices by differentmanufacturers and NCBs are driven to closer alignment.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Clause 1 (General) Sub-clauseDiscussionImpact1.7.2.3Overcurrent Protective DevicesNew sub-clause provides User Instructionrequirements associated with overcurrent protectivedevices. Aligned with second paragraph of 2.7.1.None. Clarification, and generally reflects present practice because of existing requirement in 2.7.1.1.7.3Short Duty CyclesRevised sub-clause reworks requirements for ITE not intended for continuous operation, and adds new term/definition “RatedResting Time” to complement existing term/definition “Rated Operating Time.”None. Clarification, and generally reflects present practice. A very small percentage of ITEinvestigated to IEC 60950-1 is affected by this sub-clause because most ITE is intended for continuous operation.See comments on 1.2.2.1, 1.2.2.2 and 1.2.2.3.1.7.11 DurabilityAdds alternative solvent that may be used for Durability testing, which is a type that is easier to identify andlocate in North America and some other regions. This was an important change since during factory and test lab audits it was becomingincreasingly difficult to prove to auditors the solvent used for durability testing was that specified in the First Edition of IEC 60950-1.Minor (-). Provides practical solution to previous material sourcing difficulties.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Clause 2 (Protection from Hazards) Sub-clause DiscussionImpact2.1.1.1Access to Energized PartsConnectors withconfigurations that comply with IEC 60309, IEC 60320, and IEC 60906-1 & –2 have been added as being exempt from test finger accessibility requirement.Minor (-). Relaxation, and generally reflects present practice.2.1.1.7Discharge of Capacitors in EquipmentNew compliance requirement instructs that when taking voltage decaymeasurements, “the result is referred to an instrument having an input impedance consisting of a resistance of 100 M ohms ± 5 M Ω in parallel with an inputcapacitance of 20 pF ± 5pf.”It appears the wording “the result is referred to…” is intended to allow formeasurements with other specifications than indicated, as long as the results are accurately adjusted accordingly.Note - The First Amendment to IEC 60950-1 2nd Edition, allows the input capacitance to be “25 pF or less.”Minor. Positive development because there has been significant inconsistency making voltage decaymeasurements due to lack of direction in the Standard.This new requirement should help promote consistency, although there likely will be some impact as different practices by differentmanufacturers and NCBs are driven to closer alignment.2.1.1.8Energy Hazards – d.c. Mains SuppliesAs a parallel requirement to existing requirements in 2.1.1.7 for ITE connected to a.c. mains supplies, ITE connected to a d.c. mains supply also is required to have at its point ofdisconnection energy levels that are not considered aHazardous Energy Level, or if hazardous, a HazardousEnergy Level that is removed within 2 seconds of disconnection.Minor (+). This is a newrequirement for ITE intended to be connected to a d.c. mains supply.However, it is expected that most manufacturers are already designing their d.c. mains-connected ITE to consider a similar level of requirements based on general safety principles. Also, most NCBs probably have either directly orCopyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clause DiscussionImpactRequirements forapplications that involve both internal capacitors and internal batteries are specified.indirectly assessed such equipment to a similar level of requirements due toconcerns with ‘backfeed’.2.1.1.9 Audio Amplifiers in ITE New requirement allows accessibility of audioamplifiers in ITE to comply with either the existing2.1.1.1 or, as an alternative, the accessibilityrequirements in 9.1.1 IEC 60065.Minor (-). Generally reflects present practice, and can be considered a relaxation in a sense since the accessibility requirements for audioamplifiers in IEC 60065 are somewhat less onerous than 2.1.1.2.1.2 Protection in Service Access Area Requirements now clarify, the Capacitance Discharge requirements of 2.1.1.7 alsoapply to PermanentlyConnected Equipment, and the time constant to be used is 10 seconds.For DC applications of permanently connectedequipment, 2.1.1.8 applies.Considerable (+). The Capacitance Dischargerequirements per 2.1.1.7 or 2.1.1.8, as applicable, have not been consistently applied to Permanently Connected Equipment in the past. However, since the time constant allowed is 10seconds, it is expected that most constructions will comply.2.2.3 Voltages Under Fault Conditions New requirement that is a clarification on the application of SELV circuitrequirements and voltage limits for power supplies and similar constructions that involve repetitive pulses (e.g., hiccup mode).Helps clarify and now discount a more onerous position sometimes taken in the past that any “repetitive” voltage peak above 42.4 Vp or 60 Vd.c. is a hazardous voltage.Minor (-). Considered a relaxation for mostconstructions that involve this circuit/performance characteristic.Generally reflects present practice due to theawareness of most NCBs with this pending change for several years.2.3.2 Separation of TNV Circuits From Other Circuits and from Accessible Parts Complete rewrite and rework of separation requirements for TNV circuits from other circuits and accessible parts.Minor (-). Most of the changes are clarifications, and generally reflect present practice. Some of theCopyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clause DiscussionImpactThe key takeaway is that itprovides more practical “separation” options that apply to modern designsinvolving telecommunication circuits, including ITE that is not earthed and ITE without isolation between SELV and TNV circuits (e.g., using SLIC chips).Sub-clause 2.3.2.4, Protection by OtherConstructions, is particularly important.revisions can be viewed as a relaxation of the technical and strict application of the published requirements in the earlier versions of 2.3.2, which were not feasible to apply to modern ITE with TNV circuits. Most NCBs have been aware of this pending change for several years and have allowed similar provisions.2.5Limited Power SourcesSub-clause was reworked to make intended application of the requirements clearer. Noteworthy is the change in classification of LPSprotection schemes from “inherently” or “not inherently” limited, to “without an overcurrentprotection device” and “with an overcurrent protection device.”Previous five (5) example constructions (e.g., output inherently limited incompliance with table 2B) have been reduced to four (4), which should help simplify the LPS determination.For sources without anovercurrent protective device (Table 2B), all max VA limits are now 100 VA, i.e., output voltages equal or less than 20 V no longer have a VA limit of 5xUoc.For such sources (Table 2B), the requirements also now clarify that measurements ofMinor (+). Generally reflects present practice. Some of the revisions can be viewed as minor relaxation of the technical and strictapplication of the previous requirements.Regarding the Isc & S measurements, formeasurements of circuits protected by electroniccircuits or PTC devices, since the previous measurement typically was made at 60 s, there could be someconstructions not designed to the new criteria. Thus the impact may be Considerable (+). However, since NEC Article 725 and Table 11, and UL 1310 Class 2 measurements for these circuits already are a 5 s measurement, the impact is not expected to be problematic to most manufacturers.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clause DiscussionImpactIsc & S are made after 5 s ifprotection is by an electronic circuit or PTC, and 60 s in all other cases.Note - The First Amendment to IEC 60950-1 2nd Ed, contains additionalrequirements addressing Integrated Circuits (ICs) used as a power-limiting function in an LPS. New Annex CC includesrequirements for ICs in order for them not to be subjected to single faults of their power limiting function. Theperformance requirements are based on existingrequirements being applied by some NCBs, including UL’s component certifications under QVGS2, Protectors, Low-Voltage Solid-State Overcurrent – Component.2.6.3.3Size of Protective Bonding ConductorsRework of sub-clause to clarify its intendedapplication. New Note 1 clarifies in the U.S./Canada the Protective Current Rating of a circuit associated with Pluggable Equipment Type A is 20A.None. Clarification. Reflects present practice.2.6.3.4Resistance of Earthing Conductors and Their TerminationsFurther revision and rework of this sub-clause to provide additional clarification of the intent of the requirements.Clarifies application ofresistance and voltage drop limits to (a) SELV and TNV circuits that are earthed, and (b) transformer secondary windings that are earthed.Also, incorporates much of what was previously aMinor (+). Technically, the revisions to IEC 60950-1 2nd Edition result in a relatively more onerous set ofrequirements. However, for manufacturers whopreviously had designed for a North American market, since this level ofrequirements has been part of CSA/UL 60950-1 for several years as National Differences, the true impact likely will be relatively minor.Copyright © 2010 Underwriters Laboratories IncAll Rights Reserved. Do Not Reproduce without Permission.Sub-clause DiscussionImpactNational Difference in theU.S./Canada Standard based on the trip characteristics of overcurrent protection devices used in the U.S./Canada, e.g., test duration is 120 seconds at 200% of the Protective Current Rating for circuits protected by devices with a Protective Current Rating up to 30 A.Also, provides specific, new compliance criteria for Protective BondingConductors associated with TNV and cable distribution system circuits and used to comply with separation requirements.2.9.4Separation from Hazardous VoltagesFormer 2.2.3.1 (Separation by Double/Reinforced Insulation - Method 1), 2.2.3.2 (Separation byEarthed Screen - Method 2), and 2.2.3.3 (Protection by Earthing of the SELV Circuit - Method 3) have beenreorganized into new 2.9.4, Separation from Hazardous Voltages.Clarification is provided that other constructions can be used that provide equivalent separation.None. Editorial and Clarification.2.10.1.7Insulation in CircuitsGenerating Starting PulsesNew clarification on the application of insulation requirements to circuits associated with thegeneration of starting pulses used to ignite discharge lamps.If the circuit is a Limited Current Circuit (LCC), Functional Insulation isMinor. Generally reflects present practice, although there could be some impact as different practices bydifferent manufacturers and NCBs are driven to closer alignment. Most NCBs have been aware of the pending changes for several years and have allowed similar provisions.。

敬请参考表 2L 以了解各产品应有的沿面距离要求。
若您的产品所测出的工作电压介于表中指定的两个工作电压值之间，您可利用线性内插法 (Linear Interpolation) 计算出所需要的沿面距离。
请参见表 2L 之附注2。
现在就由以下的举例，示范线性插入法的计算运用。
范例 = 电路信息输入电压：100-240V AC测出的工作电压：365 Vms, 890 V peak污染等级：2材料类别：IIIa 或 IIIbQ1a：如何计算基本绝缘需要的沿面距离？300V 需要的沿面距离 = 3.2mm400V 需要的沿面距离 = 4.0mm(4.0－3.2)÷(400－300)×65＝0.523.2＋0.52＝3.72A1a. 基本绝缘需要的的最小沿面距离 = 3.8mm注意事项：须根据表 2L 之附注2，以无条件进入的方式算到最接近的 0.1 mm 单位。
Q1b. 如何计算加强绝缘 (Reinforced Insulation) 需要的沿面距离？公式：(基本绝缘需要的沿面距离) ×2==== > 3.72×2=7.44A1b. 加强绝缘需要的的最小沿面距离 = 7.5 mm注意事项：须根据表 2L 之附注2，以无条件进入的方式算到最接近的 0.1 mm 单位。
须先将基本绝缘所需的最小沿面距离加倍后，再用无条件进入的方式算到最接近的 0.1 mm 单位。
