1.1 本试验方法包括通过暴露后材料选定性能的变化来测量夹层板对严重暴露条件的耐受性。试样的暴露周期为任意试验，与自然风化条件无关。 1.2 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。 1.2.1 例外情况- 英寸-磅单位仅供参考。 1.3 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 3.1 大多数夹芯板受到各种温度和湿度环境的影响。 该实验室老化试验确定了所选面板在模拟条件下的性能退化。 3.2 这些测试方法提供了获取模拟环境退化数据的标准方法，用于质量控制、验收规范测试和研发；然而，这些实验室老化试验程序与自然风化条件没有任何相关性。

1.1 This test method covers the determination of the resistance of sandwich panels to severe exposure conditions as measured by the change in selected properties of the material after exposure. The exposure cycle to which the specimen is subjected is an arbitrary test having no correlation with natural weathering conditions. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception— The inch-pound units are provided for information only. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 3.1 Most sandwich panels are subjected to various temperature and humidity environments. This laboratory aging test determines the selected panel property degradation under simulated conditions. 3.2 These test methods provide a standard method of obtaining simulated environmental degradation data for quality control, acceptance specification testing, and research and development; however, these laboratory aging test procedures do not have any correlation with natural weathering conditions.
