ASTM D1148-2013适用范围

4.1 The surface of white or light-colored vulcanized rubber articles, or vulcanized rubber covered with an organic finish, may discolor when exposed to conditions of humidity, or moisture, heat, and sunlight. This change in color of light-colored rubber surfaces is objectionable to the consumer.

4.2 Results obtained should be treated only as indicating the effect of irradiance from the specified source (either UVA-340 lamps or a xenon arc with a Daylight Filter) and not as equivalent to the result of any natural exposure, unless the degree of quantitative correlation has been empirically established for the material in question.

4.3 This test method may be used for producer-consumer acceptance, referee purposes, and research and development work.

1.1 This test method covers techniques to evaluate the surface discoloration of white or light-colored vulcanized rubber that may occur when subjected to UV or UV/visible exposure from specified sources under controlled conditions of relative humidity, or moisture, and temperature.

1.2 This test method also describes how to qualitatively evaluate the degree of discoloration produced under such conditions.

1.3 The term x201c;discolorationx201d; applies to a color change of the rubber sample, as distinguished from staining (see Note 1), that refers to a color change of a metal finish in contact with or adjacent to the rubber specimen.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.

Note 1x2014;Tests for staining are covered by Test Methods D925.

4.1白色或浅色硫化橡胶制品的表面,或覆盖有有机面漆的硫化橡胶,暴露在潮湿、潮湿、高温和阳光下时可能会变色。浅色橡胶表面的这种颜色变化会引起消费者的反感。


4.2获得的结果应仅视为指示指定光源(UVA-340灯或带日光滤光片的氙弧)的辐照度效应,而不是等同于任何自然照射的结果,除非已根据经验确定了相关材料的定量关联程度。


4.3本试验方法可用于生产商-消费者验收、仲裁以及研发工作。


1.1本试验方法涵盖了评估白色或浅色硫化橡胶表面变色的技术,该变色可能是在相对湿度、湿度和温度受控条件下,从指定来源受到紫外线或紫外线/可见光照射时发生的。


1.2本试验方法还描述了如何定性评估在此类条件下产生的变色程度。


1.3术语x201c;变色X201D;适用于橡胶样品的颜色变化,区别于染色(见注1),即与橡胶样品接触或相邻的金属表面的颜色变化。


1.4以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。


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)。本标准的使用者有责任在使用前建立适当的安全和健康实践,并确定监管限制的适用性。


注1x2014;染色试验包含在试验方法D925中。
