1.1 本规程涵盖光伏组件目视检查的程序和标准。 1.2 光伏组件的外观检查通常在组件经过环境、电气或机械应力测试之前和之后进行，如热循环、湿度冷冻循环、湿热暴露、紫外线暴露、机械负载、冰雹冲击测试、户外暴露，或者可以是光伏模块测试序列的一部分的其他应力测试。 1.3 此做法不确定合格或不合格级别。可接受或不可接受结果的确定超出了本规范的范围。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 环境压力测试，如 1.2 ，通常用于在生产或购买之前评估模块设计。这些测试方法依赖于在压力测试前后对模块进行电气测试和目视检查，以确定暴露的影响。 4.2 环境压力测试的影响可能从没有影响到显著变化不等。当没有可测量的电气变化时，模块中的一些物理变化可能是可见的。类似地，模块中的电气变化可能在没有可见变化的情况下发生。 4.3 本规程旨在提供公认的目视检查程序，并规定应报告的影响。 4.4 其中许多影响是主观的。为了确定模块是否通过了目视检查，本规程的用户必须指定可接受的更改或条件。用户可能必须判断在检查期间记录的变化是否会限制模块设计的使用寿命。

1.1 This practice covers procedures and criteria for visual inspections of photovoltaic modules. 1.2 Visual inspections of photovoltaic modules are normally performed before and after modules have been subjected to environmental, electrical, or mechanical stress testing, such as thermal cycling, humidity-freeze cycling, damp heat exposure, ultraviolet exposure, mechanical loading, hail impact testing, outdoor exposure, or other stress testing that may be part of the photovoltaic module testing sequence. 1.3 This practice does not establish pass or fail levels. The determination of acceptable or unacceptable results is beyond the scope of this practice. 1.4 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. 1.5 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 ====== 4.1 Environmental stress tests, such as those listed in 1.2 , are normally used to evaluate module designs prior to production or purchase. These test methods rely on performing electrical tests and visual inspections of modules before and after stress testing to determine the effects of the exposures. 4.2 Effects of environmental stress testing may vary from no effects to significant changes. Some physical changes in the module may be visible when there are no measurable electrical changes. Similarly, electrical changes in the module may occur with no visible changes. 4.3 It is the intent of this practice to provide a recognized procedure for performing visual inspections and to specify effects that should be reported. 4.4 Many of these effects are subjective. In order to determine if a module has passed a visual inspection, the user of this practice must specify what changes or conditions are acceptable. The user may have to judge whether changes noted during an inspection will limit the useful life of a module design.
