SRS-071
孩之寶公司公司質量保証安全和可靠性規定SRS-071標題：EMC測試擬制：J.JONES 批准：日期：3/20/1998 版本：A1.0目的建立評估電子產品的准則以确保滿足EMC指令(92/32/EEC)的要求。
實施EMC要求是用來确保產品不產生過量電磁輻射而對其它電器設備的正常功能產生不利影響。
此外，通常應保護電子產品以确保它們不易受電磁干扰(抗扰性)。
2.0范圍2.1 可應用產品作為成品投放市場的所有電子產品。
因此，它包括所有的電子玩具，電子构造工具箱，電子實驗設備，無線電控制車，收音机，接收&廣播產品，電池充電器和變壓器/電源以及家庭，商業和工業使用的電器產品。
2.2Consensus排除的產品盡管石英手表和白熾燈(燈泡)(非熒光燈)是成品電子產品，但在21/11/95 歐共体成員國政府專家之間的協議中被免除。
2.3由替換指令排除的產品未包括的其它成品，因為有一個對92/32/EEC的替換指令來包括更多的專業化EMC要求。
該類產品實例有：馬達車輛(72/245/EEC)，活性醫學移植器械(90/385/EEC)，飛机設備(EEC3922/91)和海上設備(COM(95)269)。
2.4由制造商危險分析(部分)排除的產品根据制造商危險分析可确定EMC指令要求的排除。
從所有或部分指令要求中對符合指令范圍內的電子產品進行排除的決定只能由對決定負責的制造商進行。
例如：電池操作玩具( 未帶有任何無線電相關功能)，由于操作玩具不會因EMC干扰造成潛在危險，通常由制造商從抗扰性要求中排除；參考指令的基本安全和保護要求。
3.0定義3.1 EMC電磁兼容性。
3.2EMC輻射每個電子產品發射的不可見電磁波。
3.3EMC抗扰性電子產品對放置在其附近的電子產品的EMC輻射中斷其操作的抵抗程度。
3.4產品該術語是指在最普通意義下被使用的產品，也指玩具。
3.5良性某些產品有低水平的EMC輻射，則被認為是良性的。
srs技术文档说明
本文的目的是描述SRS技术文档，包括对SRS的解释说明、SRS描述规范以及规范的一个范例。
软件需求规格说明书（SRS，Software Requirement Specification）是为了软件开发系统而编写的，主要用来描述待开发系统的功能性需求和非功能性需求，以及系统所要实现的功能和目标，为项目开发人员提供基本思路，明确开发方向，节约时间提高开发效率，降低软件开发风险，节约成本。
SRS主要面向系统分析员，程序员，测试员，实施员和最终用户。
SRS是整个软件开发的依据，它对以后阶段的工作起指导作用，同时也是项目完成后系统验收的依据，还是《用户手册》和《测试计划》的编写依据。
以下是SRS的描述规范：1.功能需求按模块为单位描述功能需求，重复以下几点描述每一模块的功能需求。
1.1 模块1第一个模块。
每个模块用一个用例图表示，在写SRS时，名字使用能够表达模块功能的短语表示，而不用模块1表示。
1.1.1 用例图描述此模块的用例图。
一个用例图中有若干个Actor、用例及其关系，描述包括涉及到的所有Actor、用例及其关系。
其中，Actor是参与者；一个用例描述的是一个功能需求；关系是用例和用例之间的关系。
用例的名字使用能够表达用例目标的动词短语。
1.1.2 业务流程图用例应说明的是系统内发生的事件，而不是事件发生的方式和原因。
一个业务流程图是用来描述1.1.1用例图中的一个用例事件的业务流程操作。
下面是对业务流程图对应的这个用例的描述说明：以下是SRS描述规范的一个范例：1.功能需求1.1业务区管理1.1.1 用例图1.1.2 业务流程图业务区创建范例说明：以上范例是直放站统一通讯管理系统的SRS中的第三章节，是用来描述系统的功能需求的，其中，1.1小节描述了其中一个模块——业务区管理的功能需求。
其中包括了业务区管理这一模块的用例图，以及对这一用例图中由Actor带动的三个用例：业务区创建、业务区管理、业务区删除的业务流程图描述，列出了其中一个用例——业务区创建的业务流程图，以及对这个用例的简要说明、前置条件、后置条件、角色、触发条件、基本事件流、备选事件流、特殊需求等的描述。

Apply a 25 lb. tensile force to the wedgeperpendicular to the plane of the play yard side. (The test may be performed bysuspending a 25 lb. weight from the eyebolt with the play yard side placedin a horizontal position).7.2 Side Strength and Deflection TestsTests described in 7.2.1 and 7.2.2 shall be performed in sequence at the same locationwithout refurbishing or adjusting the test sample.SRS-069PAGE 7 OF 8REVISION A7.2.1 With the play yard sides fully erected apply a 60 lb. force vertically downward overa 2 inch length of the top edge of side for 10 seconds. Remove the force andmeasure the permanent deflection. Perform the test at locations deemed to be the weakest or the most likely to fail.7.2.2 Place a 6 inch by 6 inch wooden block 1 inch thick on the playyard floor 1 inchfrom the center of the top edge of the side. Center a 15 lb. weight on the wooden block. Apply a 40 lb. force vertically downward over a 2 inch length of the sidetop edge. Maintain the force for 10 seconds while measuring the height of the side from the edge of the play yard floor to the point of application force.7.3 Floor Strength Test (4.3.5)7.3.1 With all removable cushions removed, place a 60 lb. and a 40 lb. weight each ontoa 6 by 6 inch wood block, nominally 1 inch thick, spaced 6 inches apart andmaintain for 60 seconds. Perform the test in those locations deemed to be theweakest or the most likely to fail.7.3.2 With all removable cushions removed, allow a 40 lb. rigid weight to drop freelyfrom a height of 3 inches onto a 6 by 6 inch wood block, nominally 1 inch thick.Conduct the drop 60 times in the same place with no more than 10 secondsbetween drops. Perform the test in those locations deemed to be the weakest or the most likely to fail.7.4 Mesh Opening Test (4.3.7)With the play yard and the side rails in their fully erected position, apply a force of 6 lbs. perpendicular to the plane of the mesh opening using a 3 inch diameter rod with a full-radius tip attached to a suitable force measuring device. Perform the test in thoselocations deemed to be the weakest or the most likely to fail.7.5 Dropside Rail Locking Mechanism Test (4.3.8)With the dropside rail of the play yard in its uppermost position, apply a 12.5 lb. load to the locking mechanism in the direction tending to unlock it. The locking mechanismshall not unlock until the 12.5 lb. load has been exceeded.SRS-069PAGE 8 OF 8REVISION A 7.6 Components Test (4.2)All components of the top rail, its pivots, hinges, locks or mechanism which are deemed to be capable of scissoring, shearing or pinching shall be tested in accordance with 7.6.1 thru 7.6.3.7.6.1 At all intersections of the "drop top rail" with the "top rail saddle", the insertion of a probe greater than 0.210 inches in diameter and less than 0.375 inches in diameter and greater than 0.210 inches deep within the intersecting parts in any and allpositions will not be permitted.7.6.2 At all intersections of the "hinge legs" with the "drop top rail" or the the "hingelegs" and the "inclined leg" where no padding of 1/4" or less exists, a minimumclearance of 0.375 inches shall be maintained between the hinge legs, the saidlocking mechanism must allow a 0.375 inch diameter probe to pass between the said hinge legs when in any and all positions.7.6.3 At all intersections of the drop side rail locking mechanism (hinge legs with thesaddle) the insertion of a probe greater than 0.210 in. in diameter and less than0.375 in. in diameter and greater than 0.210 in. deep within intersecting parts inany and all positions will not be permitted.。

SIS系统设计中安全要求规格书(SRS)的编制
SIS系统设计中安全要求规格书（SRS）的编制一、安全要求规格书SRS的基本介绍SRS是SIS系统设计(初设、详设以及全生命周期设计及使用阶段管理)的基础，也是SIS系统最终确认的依据，因此所有必须的信息都应该包括在内，形成一整套完整的文件。
SRS是整个安全生命周期中重要的一环，通过SRS可以知道怎样设计一个安全仪表功能(SIF)，以及如何把这些功能(SIF)集成到一个SIS中。
安全功能要求规范SRS（safety requirement specification）是包含安全仪表系统应执行的安全仪表功能的所有要求的规范。
SRS虽然在IEC61508、IEC61511中很早就提出，但是由于国内对SRS编制的详细要求还存在一定的差距和不足，因此部分企业仍然尚未编制SRS文件。
随着近几年专家频次及深度的增加，SRS文件缺失的现象被逐渐暴露出来。
SRS实施的阶段如下（来自GB/T 20438.1-2017）：二、安全要求规格书(SRS)的安全要求（摘自GB/T 20438.1-2017 7.10）1. E/E/PE系统安全要求规范应来自7.6中指定的安全要求的分配，并结合应用的相关信息。
这些信息应提供给E/E/PE安全相关系统的开发者。
2. E/E/PE系统安全要求规范应当包括安全功能的要求以及它们相应的安全完整性等级。
注：描述安全功能利它们所需的功能安全性能.而并不特指设备。
此规范可以依据整体安全要求和整体安全要求分配阶段的输出进行验证,并可作为E/E/PE系统实现（见GB/T 20438.2—2017的7.2）的基础。
设备设计者可-将规范作为选择设备和架构的基础。
3. E/E/PE系统安全要求规范应当提供给E/E/PE安全相关系统的开发者.E/E/PF：系统安全要求规范的结构和表达应当按如下方式：a）清晰、准确、不含糊、可验证、可测试、可维护且切实可行;b）便于在E/E/PE系统安全生命周期任何阶段使用此信息的工作人员理解；c）安全功能的要求可以通过自然语言或正式语言和/或逻辑图、顺序图或因果图表述，每个安全功能应单独定义。
