UL线材标准
(三)耐电压测试
电缆中各导线间应施加UL62Table51.1相对应的电压,加压时应 在10S至60S钟内缓慢将电压由零加到额定值,保持1分钟。判别 标准为在升、降压以及保持期间,Hi-pot机电路报警。另一方 面,绝缘电阻测试在某种程序上也能产生类似效果,所以先进 行耐电压测试是一种积极的简便测试漏电的方法。
拉伸速率:在UL1581第50节各表中未特别指明拉伸速率时,通常情况 下速率为500+25mm/min.
2、如何决定材质的拉伸指数?
UL62现在已将常规可弯曲软线的物性归结在Table5.2(绝缘体)和 Table7.2(外被)中。
过去所有电线塑料材质的物性全部列入UL1581 Table50系列。例如SPT2,105 ℃电线,其物性要求为:SPT-2为Integral PVC电缆,故应用 UL62Table15.1或UL1581 Table50182。105 ℃对应的CLASS是2.11,拉伸指 数为老化前拉伸率100%,抗张强度1500ibf/m2。136 ℃,7天的老化后 拉伸率为之前的65%,抗张强度为老化前的85%。而对于半硬PVC而言 (SR-PVC),根据UL1581Table47.1,拉伸指数在Table50183中列明,即 老化前,拉伸率100%,抗张强度3000ibf/m2,老化后百分比分别为70%, 70%。

2、测量工具,读数显微镜
取样时,小心抽取全部导体芯线,沿导线绝缘体方向垂直切片,在显微镜下测 量最薄处的厚度,作为导体绝缘层的最小厚度。
通常将读数显微镜(精度为0.001mm)的测量结果作为最终的参考标准。实际测 量时发现一卷电线测量的最小厚度小于规定值多过2Mils,判定该卷电线不合格。 若测量值小于规定值不超过2Mils,应在该卷电线上相距1英尺处抽取两个样测量, 如果其中1个结果小于最小值,该卷电线判为不合格,若两个测量值均达标,判 为合格。

绞距
芯线绞距 取芯线10个绞合的间距的平均值作为芯线平均绞距,测量时去 除大约十个绞合长度的绝缘外皮,取任何一支芯线为对象进行 测量。注意在去皮时不要损伤芯线,造成芯线断线。 导线绞距 同样取导线的10个绞距长度进行平均,作为平均导线绞距,取 样时要注意由于导线绞合时的内应力一扭力很大,去除外被时 可能造成原绞合结构的松散。为此,取样时先预留一段护套线 不去除外被,再沿线缆方向用利刀片拉掉部分外被,最好是以 能看到待测导线,而导线与外被结合得仍很紧密为宜。将样品 平放拉直,量取某一导线十个绞合点之间的距离作为绞距,因 为成缆时由于应力的关系,成形外被后原绞合距离会增加。 各种芯线最大绞距参见UL62。各种线径的导线最大绞距参见 UL62

68Each year millions of feet of wire and cable are installed in all types of buildings and for use in many different environmental conditions. Because of the choices available, it is important to know which wiring systems are suitable for a specific situation. It is also important to be able to properly identify these systems. Markings on or associated with the product, the UL Listing, Classification, or Verification information, and requirements in the current edition of the National Electrical Code®all convey the information needed to ensure a compliant installation. This publication explains markings found on Underwriters Laboratories Inc. Listed, Classified, or Verified wire and cable. Appendices B and C also contain the Listing, Classification, or Verification information for the product categories involved. UL Online Certifications Directory Listings, Classifications, and Verifications are updated daily. To confirm the current status of any UL record, please consult UL’s Online Certifications Directory at .Although they may be broadly worded, required or optional product markings (and their locations) are specific to the product with which they are associated. This document is intended to be used in determining the suitability of a particular UL Listed, Classified, or Verified wiring product that complies with all the applicable UL requirements, in a particular application.To confirm the current status of any UL Marking Guide, please consult the Regulators page of the UL Web Site at /regulators/index.html.Your comments or suggestions are welcome and appreciated. They should be directed to:Austin D.

Toward this goal, the guide:1.Clarifies the means used to identify UL Listed,Classified, or Verified wire and cable (see the sectionstitled “Identification of Listed Products”, “Identification of Classified Products,” "Identification of VerifiedProducts).2.Provides an explanation of the ratings and intended uses of UL Listed, Classified, or Verified wire andcable (see Appendix A for designations).3.Focuses on the information contained in UL Listed, Classified, or Verified wire and cable product markings(what the markings mean, where they may be located, etc.).This guide does not address wire and cable evaluated only for suitability as factory-installed component wiring in other Listed equipment. Those products are Recognized by UL under the Component-Appliance Wiring Material (AWM) and Component-Nonshielded cable categories and are not identified with an NEC® wire Type designation.In general, Component Wire or Cable is not evaluated for field installation unless it is included as a part of a complete, Listed product or system. For example, data processing equipment Listed under the Information Technology Equipment Including Electrical Business Equipment (NWGQ) category will use external interconnect cables, such as AWM Style 2464, only if the AWM has been evaluated and described in the Listing for the particular piece of equipment. The limitations on the installation of the Listed end-use product or system also apply to the wiring. Some interconnect cables may have connectors assembled on one or both ends as a computer-interconnection assembly. When these assemblies use Recognized cable and are sent to a building site separately, instead of being supplied with the equipment, these cable assemblies may be identified as Listed Computer Interconnection Cable Assemblies (DVPJ). Similarly, for communication equipment, Listed Communication Cable Assemblies (DUNH) may be used. AWM ratings and conditions of acceptability are shown on a tag affixed to the reel or carton. Some ratings may appear on the surface of the wire or cable.The UL label is required for Listed, Classified, and Verified wire and cable products and can be applied in various manners. It can be applied to a coil, reel, flange, or box. This label is the only means used to indicate that the product is covered under UL testing (Listing, Classification, or Verification) and UL Follow-Up Service. The UL symbol or letters "UL" on the wire/cable itself is only a supplemental method of identifying UL coverage and should not be considered primary evidence of UL coverage. UL's Guide Information (see Appendices B-D) will indicate if the UL symbol or letters on the product itself is required. The required engineering markings, which appear on the product itself, are only intended to provide information related to the product's ratings or testing scope.This guide should be particularly useful for those who:1.Have a working knowledge of the current edition of the National Electrical Code® (NEC®) and howlocally applicable electrical codes relate to the NEC®.2.Are already familiar with the requirements of the electrical installation under consideration.3.Can identify the cable as a particular NEC type.This guide is intended to supplement the Guide information for the appropriate wire and cable category in UL’s Electrical Construction Equipment Directory (green book), UL’s General Information for Electrical Equipment Directory (white book), and the NEC®. The Guide information for each of the applicable categories of Wire and Cable is included in Appendix B (Listing), Appendix C (Classification), and Appendix D (Verification).12HOW TO USE THIS GUIDEThe wire and cable types covered in this guide have been divided into three tables as follows:Table 1 —Building Wires and Cables, including some industrial cables Table 2 —Low Voltage Cables, Flexible Cords, and Fixture Wires Table 3 —Special Purpose Wire and CableIn each table, wire and cable types are identified by the name of the category under which they appear in UL’s Electrical Construction Equipment Directory. Most wire and cable types have the same category designation in the NEC ® as they do in UL’s Electrical Construction Equipment Directory.Definitions of the column headings and codes used in each column are provided in the section titled “Explanations and Notes for Marking Tables.” Table entries consist of:Table Entry IndicatesYesThe wire or cable is always evaluated for the use specified by the particular column. These uses are explained in the section titled “Explanations and Notes for Marking Tables.”— (dash)The wire or cable is not evaluated for the indicated use, either as a requirement or as an option.NumbersA specific rating. For example, 250 in the column headed by “Temperature (o C) Dry” indicates a 250o C temperature rating for dry locations.Specific notes detailing a rating and/or associated marking. The explanations of the notes can be found in “Explanations and Notes for Marking Tables,” following the tables.Numbers in parentheses e.g., (3), (21)3IDENTIFICATION OF LISTED PRODUCTSThe UL Mark may have various information around it as authorized by Underwriters Laboratories Inc.The Listing Mark of Underwriters Laboratories Inc. on the attached tag, the reel, or the smallest unit container in which the product is packaged, with or without the UL symbol on the product, is the only method provided by UL to identify these products manufactured under its Listing and Follow-Up Service. The Listing Mark for these products includes the UL symbol (as illustrated above) together with the word “LISTED,” a serial number, and the product or category name.A product bearing the UL Mark for Canada is Listed to Canadian Standards for that specific product. A product bearing the combined Canada/U.S. Mark is Listed to both UL’s (U.S.) Standards and Canadian Standards for that specific product.For wire and cable products, the complete Listing Mark is located on a tag attached to the reel or smallest unit container.Two types of UL symbols — “UL” in a circle or “UL” in parentheses — may be found on the wire or cable itself. These UL symbols may also be preceded by the letter “C”, indicating certification only for Canada, or preceded by a “C” and followed by “US”, indicating certification for both the US and Canada. The product markings are intended to provide information only, and the complete Listing Mark is the only proof that a particular unit of wire or cable is actually Listed.IDENTIFICATION OF CLASSIFIED PRODUCTSWith UL’s Classification Service, UL determines that a manufacturer has demonstrated the ability to produce a product that complies with its requirements for the purpose of classification or evaluation regarding one or more of the following:(1) specific risks only, such as casualty, fire or shock; (2) performance under specified conditions; (3) regulatory codes;(4) other standards, including international and regional standards; or (5) other conditions UL may consider desirable.UL conducts a Follow-Up Service as an audit of the means the manufacturer uses to determine continued compliance of the product with UL’s requirements.The UL Classification Marking may appear in various forms as authorized. The Classification Marking includes: (1) the symbol of Underwriters Laboratories Inc. – ; (2) the word “CLASSIFIED”; (3) a product identity and a statement to indicate the extent of UL’s evaluation of the product such as “AS TO (nature of hazard) ONLY,” or a rating or classification as specified in the general information pertaining to the product category, or designation and title of standard published by other organization, or identification of specified product; and (4) a control number assigned byUL.For use in the USA For use in CanadaFor use in both the USA and Canada(PRODUCT IDENTITY)IN ACCORDANCE WITH (Specification or Requirement)(Control Number)(PRODUCT IDENTITY)AS TO ONLY(Control Number)— OR —— OR —(PRODUCT IDENTITY)AS TO ONLY(Control Number)IDENTIFICATION OF VERIFIED PRODUCTSThe UL Verification Mark is used to identify products evaluated under UL’s Performance Verification Services. Some examples are products tested under the UL Performance Verification program for cable, Levels XP Structured Cabling Program, Proprietary Structured Cabling Program, ISO/IEC 11801, TIE/EIA 568B, Telcordia, and NEMA.The presence of this mark provides assurance to end-users, IT managers, LAN system designers, and the regulatory community that products have been evaluated for transmission performance, in order to meet the unique needs of the telecommunications industry community.There are two formats to the Verification Mark (label) that appear on products: Listing and Verification (As shown in Illustration A below) and Verified-Only (As shown in Illustration B below).Listed cable tested under the UL Performance Verification Program for cable in accordance to TIA/EIA 568B have the label marking “Listed Communications Cable” also “Verified to UL Performance Category Program,” on the tag,reel or smallest unit container, as shown in Illustration A. Cable Verified to another transmission performance specification, (NEMA WC63, 63.1, 66, ISO 11801, Telcordia, etc.), have the label marking “Listed Communications,Cable” also “Verified in Accordance with [Specification name and/or number]” on the tag, reel or smallest unit container.In addition, surface marking on these products would be as follows:1) For performance Category Cable:. “Verified (UL) Category 3, 4, 5, 5E or 6 [including latest draft number ifapplicable].2) For performance Category Pat Cable: “Verified (UL) Category 3, 4, 5, 5E or 6 [including latest draft numberif applicable] Patch; Cable” for stranded conductor cables.3) For all other Performance Verified Cable: “Verified in Accordance with [Specification name and/or number]”Cabling products that are Verified Only (Non-UL Listed) will use the label as shown in Illustration B. The Verification Mark of Underwriters Laboratories Inc. on the attached tag, the reel, or the smallest unit container in which the product is packaged is the only method provided by UL to identify products manufactured under this Verification and Follow-Up Service. The Verification Mark for these products includes the UL symbol together with the word “VERIFIED,” a control number, the product name “Data Transmission Cable”, and the Specification name and/or number. In addition to the marking on the tag, reel, or smallest unit container, cables that have been Verified by UL in accordance with the signal transmission characteristics, and have not been Listed by UL as Communications Cable, Power-Limited Circuit Cable,or other UL Listed Cable, are surface marked with the statement “Verified by Underwriters Laboratories Inc. in accordance with [Specification name(s) and/or number(s)] Only” in the surface print legend. The UL symbol [either the UL in a circle symbol or “(UL)”] is not used in place of the wording “Underwriters Laboratories Inc.” in the statement.Cabling products tested under the Levels XP Structured Cabling Program and the Proprietary Structured Cabling Program are field assembled cabling and connectivity products. The Type R UL Verification Mark (label) is not directly applied to structured cabling products. The complete Verification Mark (illustrated below) may appear on a Bill of Lading,a Bulk Shipment Certificate, or on UL’s Certificate or Conformity Assessment.In these cases, the Mark must be reproduced in its entirety and clearly associated with the structured cabling product which was investigated by UL.VERIFIED Levels XP ProgramSolution Name and Part NumberControl Number4Illustration BISSUE #GENERAL CHARACTERISTICSMarkingsThe requirements for the exact text and location of the markings, and the method of identification, vary among the different types of wire and cable. Wherever possible, the product is surface marked with information necessary for proper installation. When surface marking is not possible — or for other considerations — all or a portion of the marking may be located on a tag, reel or the smallest unit container as permitted by the requirements of each product category. Whenever possible, the rating or characteristic is plainly indicated. Other methods — for example, colored tracers under the jacket or insulation — may be used to identify a certain characteristic, such as temperature rating for some fixture wires. To completely determine the suitability of a particular wiring system, review of the product itself, tag markings and carton markings may be necessary.Some wire and cable may be marked with multiple Type designations. These products have been evaluated for uses of all Type designations marked.All markings on or associated with wire and cable, as well as the Listing information of the appropriate category (see Appendix B), should be consulted to determine all ratings and limitations for proper installation in accordance with requirements of the NEC®.UL evaluates wiring products with respect to the marked ratings and uses indicated by the Type designation associated with the UL Mark. Wiring products are not evaluated with respect to marked ratings and uses associated with other certification organizations.Conductor MaterialCompact stranded copper conductors are identified by “compact” or “cmpct,” otherwise wire and cable with bare or coated copper conductor material is not marked with stranding identification.If the conductor material is either aluminum or copper-clad aluminum, the product, tag or carton markings (depending on the product category) identify the conductor material. These markings will appear as “AL,” “ALUMINUM,” “AL (CU-CLAD),” “ALUMINUM (COPPER-CLAD),” “CU-CLAD AL” or “COPPER-CLAD ALUMINUM.”For some wire and cable, other metals may be used as conductor material. The associated markings for that wire and cable are explained under the heading “OTHER.”FlammabilityUL investigates wiring products with respect to their intended locations and uses as permitted by the NEC®. Flammability or resistance to spread or propagation of fire is one of the considerations that enters into the overall investigation of wire and cable. For instance, products that are inherently permitted by the NEC® to be installed in cable trays or that are marked for such use are investigated for fire conditions that could exist in a cable tray.Similarly, cables covered for use in accordance with Articles 725, 760, 770, 800, 820, and 830 of the NEC® are investigated with respect to their application: plenum, riser, general use or restricted residential use. Suffixes to the Type designation identify the use as defined in the appropriate NEC® articles:-P Plenum-R Riser-No Suffix General purpose-X Limited residential useSome wire and cable may also have a suffix “-LS” or "ST1" which means that the entire construction complies with the requirements for flame retardant, limited smoke wiring materials as evaluated per UL 1685.5WIRE AND CABLE MARKING
