ASTM G154-16

ASTM G154-16适用范围

ASTM G154-16是个关于暴露在阳光日晒、持续潮湿、加热而导致产品性能老化的测试方法,现行标准修订于2016年。

1.1本规程仅限于操作荧光紫外线灯和水装置的基本原则;其本身并没有提供具体结果。

1.2本规范旨在与规定应用特定暴露条件的实践或方法结合使用,并用于评估材料性能变化的方法。本规程旨在再现材料在阳光(直接或通过车窗玻璃)和实际使用中的水分如雨露时产生的风化效应。本实践仅限于获取、测量和控制暴露条件的程序。

注1:规程G151描述了在使用实验室光源的加速试验装置中暴露非金属材料时使用的一般程序。

注2:附录中列出了许多暴露程序;但是,本规程并未规定最适合待测试材料的暴露条件。

1.3受控制环境条件下,试样暴露在荧光紫外线下。介绍了不同类型的荧光紫外光源。

注3:在本标准中,术语UV光和UV辐射可互换使用。

1.4试样制备和结果评估包含在ASTM方法或特定材料规范中。一般指南见实施规程G151和ISO?4892-1。

注4:ISO?4582和规程D5870中描述了有关测定暴露后性能变化和报告这些结果的方法的一般信息。

1.5 SI单位中规定的值应视为标准值。本标准不包括其他计量单位。

1.6本标准并不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。

1.7本标准在技术上与ISO?4892-3和ISO 16474-3类似。


1.1 This practice is limited to the basic principles for operating a fluorescent UV lamp and water apparatus; on its own, it does not deliver a specific result.

1.2 It is intended to be used in conjunction with a practice or method that defines specific exposure conditions for an application along with a means to evaluate changes in material properties. This practice is intended to reproduce the weathering effects that occur when materials are exposed to sunlight (either direct or through window glass) and moisture as rain or dew in actual usage. This practice is limited to the procedures for obtaining, measuring, and controlling conditions of exposure.

NOTE 1:Practice G151 describes general procedures to be used when exposing nonmetallic materials in accelerated test devices that use laboratory light sources.

NOTE 2:A number of exposure procedures are listed in an appendix; however, this practice does not specify the exposure conditions best suited for the material to be tested.

1.3 Test specimens are exposed to fluorescent UV light under controlled environmental conditions. Different types of fluorescent UV lamp sources are described.

NOTE 3:In this standard, the terms UV light and UV radiation are used interchangeably.

1.4 Specimen preparation and evaluation of the results are covered in ASTM methods or specifications for specific materials. General guidance is given in Practice G151 and ISO?4892-1.

NOTE 4:

General information about methods for determining the change in properties after exposure and reporting these results is described in ISO?4582 and Practice D5870.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.

1.7 This standard is technically similar to ISO?4892-3 and ISO 16474-3.
