1.1本试验方法涵盖了一种程序，用于评估乙烯基涂层玻璃纱织物（如纱线、防虫网、防晒网和百叶布）在试验装置中暴露后的颜色变化，该试验装置通过喷水、控制相对湿度和使用明火碳弧光源对试样进行控制润湿。 1.2本试验方法以国际单位制和英寸-磅单位显示数值。“国际单位制”是被称为国际单位制的公制单位的技术正确名称。 “英寸-磅单位”是美国常用单位的技术正确名称。以英寸-磅为单位的数值应视为标准值。国际单位制数值仅供参考。 1.3本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题。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。 第7节给出了具体的预防说明。

1.1 This test method covers a procedure for evaluating the color change of vinyl-coated glass yarn textiles, such as yarns, insect screening, solar screening, and louver cloth, after exposure in a test apparatus with controlled wetting of the specimen by water spray, controlled relative humidity, and employing an open-flame carbon arc light source. 1.2 This test method shows the values in both SI units and inch-pound units. "SI units" is the technically correct name for a system of metric units known as the International System of Units. "Inch-pound units" is the technically correct name for the customary units used in the United States. The values stated in inch-pound units are to be regarded as the standard. The values in SI units are provided for information only. 1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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. Specific precautionary statements are given in Section 7.
