1.1 本试验方法提供了一种程序，用于确定光伏组件在安装在海洋环境中（例如漂浮助航设备）时承受海水反复浸泡或飞溅暴露的能力。模块在不同温度和重复加压下反复浸入模拟盐水中的组合环境循环暴露为评估海洋环境对模块材料和结构的老化影响提供了加速基础。 1.2 本试验方法定义了光伏模块试样和测试定位模块的要求，参考了确定电气性能和特性变化的合适方法，并规定了必须记录和报告的参数。 1.3 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。 1.4 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。 1.5 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。 1.6 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====== 4.1 部署在海洋应用中的光伏组件（如浮动导航辅助设备）的使用寿命可能取决于其承受反复暴露在盐环境中、浸泡在海水中以及与海水溅落在阳光下运行的组件上相关的温度变化的能力。 这些暴露的影响可能是模块中的物理或电气变化，或两者兼而有之。 4.2 本试验方法描述了定位试样、进行循环组合压力、浸渍和温度（PIT）试验以及报告结果的程序。它还参考了进行模块电气性能和绝缘完整性测试的方法。 4.3 本试验方法产生的数据可用于评估和比较模拟海洋环境对试样的影响。本试验方法要求记录可见效应和电气性能。 4.3.1 对模块的影响可能从无到重大变化不等。当模块中没有明显的电气变化时，可以看到模块中的一些物理变化。类似地，在模块中没有可见变化的情况下，可能会发生电气变化。

1.1 This test method provides a procedure for determining the ability of photovoltaic modules to withstand repeated immersion or splash exposure by seawater as might be encountered when installed in a marine environment, such as a floating aid-to-navigation. A combined environmental cycling exposure with modules repeatedly submerged in simulated saltwater at varying temperatures and under repetitive pressurization provides an accelerated basis for evaluation of aging effects of a marine environment on module materials and construction. 1.2 This test method defines photovoltaic module test specimens and requirements for positioning modules for test, references suitable methods for determining changes in electrical performance and characteristics, and specifies parameters which must be recorded and reported. 1.3 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. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 The useful life of photovoltaic modules deployed in marine applications (such as floating aids-to-navigation) may depend on the ability to withstand repeated exposure to salt atmosphere, immersion in seawater, and the temperature changes associated with seawater splash falling on modules operating in sunlight. The effects of these exposures may be physical or electrical changes in the module, or both. 4.2 This test method describes a procedure for positioning the test specimen, conducting a cyclical combined pressure, immersion, and temperature (PIT) test, and reporting the results. It also references methods for conducting module electrical performance and insulation integrity tests. 4.3 Data generated by this test method may be used to evaluate and compare the effects of a simulated marine environment on test specimens. This test method requires recording of visible effects as well as electrical performance. 4.3.1 Effects on modules may vary from none to significant changes. Some physical changes in the module may be visible when there are no apparent electrical changes in the module. Similarly, electrical changes may occur with no visible changes in the module.
