1.1 这些试验方法包括以下程序:( 1. )在施加用户指定电压时，测试光伏模块电路及其外部组件之间的漏电，以及( 2. )用于测试可能的模块绝缘击穿（介电耐压测试）。 1.2 描述了测量光伏模块电路及其外部组件之间绝缘电阻的程序（绝缘电阻测试）。 1.3 提供了一种程序，用于验证模块的外露外部导电表面（如框架、结构构件或边缘闭合件）与其接地点之间是否存在电气连续性（接地路径连续性测试）。 1.4 本试验方法不确定合格或不合格水平。可接受或不可接受结果的确定超出了本试验方法的范围。 1.5 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 旨在将太阳辐射能安全转换为有用电能的光伏模块或系统的设计必须考虑到如果用户接触到该模块的电势，则存在危险的可能性。 这些测试方法描述了验证模块或系统的设计和构造能够通过正常安装和使用提供冲击防护的程序。在模块上的任何位置都不应接近该电势，但预期输出引线明显除外。 5.2 这些测试方法描述了确定模块提供电气危险防护能力的程序。 5.3 这些程序可指定为涉及环境暴露、机械应力、电过载或加速寿命试验的一系列鉴定试验的一部分。 5.4 这些程序通常用于干式模块；然而，测试模块可以是湿的或干的，如适当的协议所示。 5.5 这些程序可用于验证生产线上的模块组件。 5.6 绝缘电阻和泄漏电流是模块尺寸、环境相对湿度和吸收的水蒸汽的强大函数，接地路径连续性程序受到触点和测试引线到模块框架和接地点的位置的强烈影响。 5.6.1 由于这些原因，这些测试方法的用户有责任指定介电耐压测试的最大可接受泄漏电流，以及接地路径连续性程序的最大可接受电阻。 5.6.2 50μA通常用作最大可接受泄漏电流（见ANSI/UL 1703，第26.1节），0.1Ω通常用作最大可接受电阻。 5.7 一些模块设计可能不使用任何外部金属组件，因此缺少模块制造商指定的接地点。在这些情况下，接地路径连续性测试不适用。

1.1 These test methods cover procedures for ( 1 ) testing for current leakage between the electrical circuit of a photovoltaic module and its external components while a user-specified voltage is applied and ( 2 ) for testing for possible module insulation breakdown (dielectric voltage withstand test). 1.2 A procedure is described for measuring the insulation resistance between the electrical circuit of a photovoltaic module and its external components (insulation resistance test). 1.3 A procedure is provided for verifying that electrical continuity exists between the exposed external conductive surfaces of the module, such as the frame, structural members, or edge closures, and its grounding point (ground path continuity test). 1.4 This test method does not establish pass or fail levels. The determination of acceptable or unacceptable results is beyond the scope of this test method. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The design of a photovoltaic module or system intended to provide safe conversion of the sun's radiant energy into useful electricity must take into consideration the possibility of hazard should the user come into contact with the electrical potential of the module. These test methods describe procedures for verifying that the design and construction of the module or system are capable of providing protection from shock through normal installation and use. At no location on the module should this electrical potential be accessible, with the obvious exception of the intended output leads. 5.2 These test methods describe procedures for determining the ability of the module to provide protection from electrical hazards. 5.3 These procedures may be specified as part of a series of qualification tests involving environmental exposure, mechanical stress, electrical overload, or accelerated life testing. 5.4 These procedures are normally intended for use on dry modules; however, the test modules may be either wet or dry, as indicated by the appropriate protocol. 5.5 These procedures may be used to verify module assembly on a production line. 5.6 Insulation resistance and leakage current are strong functions of module dimensions, ambient relative humidity and absorbed water vapor, and the ground path continuity procedure is strongly affected by the location of contacts and test leads to the module frame and grounding points. 5.6.1 For these reasons, it is the responsibility of the user of these test methods to specify the maximum acceptable leakage current for the dielectric voltage withstand test, and the maximum acceptable resistance for the ground path continuity procedure. 5.6.2 Fifty μA has been commonly used as the maximum acceptable leakage current (see ANSI/UL 1703, Section 26.1), and 0.1 Ω has been commonly used as the maximum acceptable resistance. 5.7 Some module designs may not use any external metallic components and thus lack a ground point designated by the module manufacturer. In these cases, the ground path continuity test is not applicable.
