此提案仅供审核和评论(此时不进行投票)。请注意，关于初步审查文件的意见将不会通过

CSDS收到提案作者的回复。不过，提案作者将被要求审查意见，并根据作者认为适当的方式调

整提案和/或支持理由。

初步审查过程是一种非正式机制，为作者提供了在UL到标准制定过程下一阶段之前完善其

提案的机会。

在某些情况下，提案的作者可能会选择中止。在这种情况下，作者在初步审查结束后不需要

做任何事情。通常，这个过程的下一步是更加正式的STP投票和利益相关者审查过程。只有在

STP投票和利益相关者审查过程中发表的评论才会在CSDS中提供回应。

为了方便审查，现有要求的拟议增加显示为下划线，建议删除内容列出。

6词汇表

6.1为了本标准的目的，适用以下定义。

6.2DUT-被测设备。

6.3能源存储（ES）系统-通过电化学或其他方式提供储存能量的设备，供以后使用以供应公

用电网或本地电网。能量存储系统可以利用以下技术之一：

a）电化学能量储存系统-由二次电池，电化学电容器，流动电池或混合蓄电池-电容器系统

组成，用于存储能量和任何可根据需要提供电能的相关控制或装置。

b）化学能源储存系统-由供氢设备或与燃料电池电力系统或发甩机组合的其他燃料供应设备组

成，以将燃料转换为电能。

c）机械能源储存系统-包括通过压缩空气，抽水或飞轮技术储存能量的机械手段，以及相关的

控制和系统，可用于运行发电机以根据需要提供电能。

d）热能储存系统-包括使用加热流体（如空气）作为储存能量的手段以及相关控制系统的系统，

可用于运行发电机以根据需要提供电能。

6.4电击危险-通过直接接触保护外壳中的开口和/或危险电压电路和可触及部件之间的绝缘不

足，可能使人员暴露于危险电压电路。

6.5外壳-能量存储系统的外盖，可保护其内容物。

6.6燃料电池系统-将燃料和氧化剂形式的化学能转化为电能的设备，具有反应的热和副产物。

6.7危险电压-

在美国，电压超过30Vrms/42.4Vac峰值或60Vdc。

在加拿大，电压超过30Vrms/42.4Vac峰值或42.4Vdc。

6.8绝缘水平-以下是电绝缘水平：

a）基本-单级绝缘，提供防电击保护。如果绝缘层发生故障，单独的基本绝缘不能提供防电击

保护。

b）双重绝缘-绝缘包括基本绝缘和辅助绝缘。

c）功能绝缘-绝缘仅对设备正常工作是必需的。绝缘功能绝缘不能防止触电。但是，可能会降

低点火和起火的可能性。

d）加强绝缘-在本标准规定的条件下，提供相当于双重绝缘的触电防护等级的单一绝缘系统。

术语“绝缘系统”不意味着绝缘体必须在一个均匀的部件中。它可以包括几个不能作为基本绝缘

和辅助绝缘测试的层。

e）辅助绝缘-除了基本绝缘外，还应采用独立绝缘，以减少基本绝缘故障时的触电危险。

6.9限制访问位置-以下两种能力存储系统设备的位置：

a）只能由服务人员或被指示使用该地点限制理由的使用者以及应采取的预防措施获取通路;和

b）访问是通过使用工具或锁和钥匙或其他安全手段进行的，并由负责该位置的机构控制。

6.10室内环境-被认为是25±5°C（77±9°F）范围内的温度。

6.11安全关键电路/组件-在15.2的安全分析中确定的那些依赖于安全性的电路或分立组件。

7非金属材料

7.1用于外壳的材料应符合“高分子材料标准”•电气设备评估标准“UL746C”，“外壳要求

的第III路径”或“聚合材料性能评估标准”C22中概述的适用外壳要求。2号0.17。

7.2在评估使用非金属材料的外壳时，应考虑(a)-(e)中的以下因素。对于非金属外壳，所

有这些因素都将考虑热老化。聚合物外壳的尺寸稳定性通过符合模具应力消除测试来解决。以下

因素(a)-(e)的适用性可以通过本标准的测试来确定

a)抗冲击;

b)抗压性；

c)异常操作；

d)严重条件;和

e)模具应力消除变形。

7.3系统中用作电气绝缘的材料应能抵抗会导致触电，火灾或其他安全隐患的劣化。绝缘材料与

危险活性部件直接接触或接近危险的活性部件,符合“聚合材料标准”中的“材料特性注意事项”

表格6.1・电气设备评估中使用的评估，UL746c或“性能评估标准”高分子材料C22.2第0.17

号应另外符合该标准中概述的绝缘标准，除非作为已被评估为合适组分标准的组分的一部分使用。

绝缘布线符合第11节中概述的要求。

7.4垫片和密封件依赖于安全性，应确定适合其最终用途中预期会暴露的环境条件和化学物质。
