1.1 本试验方法涵盖了评估飞机型玻璃纤维毡绝缘层对芯水倾向的实验室程序。 1.2 材料的芯吸特性会受到环境条件（如温度和湿度）的影响。根据本试验方法获得的数值不能充分描述受试验方法中规定以外条件影响的材料的芯吸特性。（见规范 C800 .) 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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。 1.5 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 绝缘材料的芯吸倾向可能导致重量增加，并导致绝缘材料性能的潜在退化。

1.1 This test method covers a laboratory procedure for evaluating the tendency of, aircraft type, fibrous glass blanket insulation to wick water. 1.2 The wicking characteristics of materials can be affected by environmental conditions such as temperature and humidity. Values obtained as a result of this test method does not adequately describe the wicking characteristics of materials subject to conditions other than those indicated in the test method. (See Specification C800 .) 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 ====== 5.1 The tendency of the insulation toward wicking can result in an increase in weight and a resultant potential degradation in the properties of the insulation.
