ASTM G151-19适用范围

1.1本实施规程涵盖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。有关用于特定设备的程序的详细信息，请参见描述所用特定设备的标准。例如，关于使用明火碳弧、封闭碳弧、氙弧和荧光紫外光源的装置中的曝光的详细信息分别见实施规程G152、G153、G154和G155。

注1：实践G23、G26和G53中也描述了碳弧、氙弧和荧光紫外线曝光，这些实践涉及非常具体的设备设计。规程G152、G153、G154和G155是基于性能的标准，取代规程G23、G26和G53。

1.2本实施规程还描述了用于将非金属材料暴露于实验室光源的装置的一般性能要求。此信息主要用于实验室加速曝光设备的生产商。

1.3本规程提供了加速暴露试验数据的使用和解释信息。关于非金属材料暴露前后性能测定方法的具体信息，见描述测量每种性能方法的标准。规程D5870中描述了有关塑料材料暴露试验结果报告的信息。

注2：指南G141提供了解决非金属材料暴露试验可变性的信息。指南G169提供了暴露试验结果统计应用的信息。

注3：本标准在技术上等同于ISO?4892第1部分。

1.4本标准无意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建立适当的安全、健康和环境实践，并在使用前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》中确立的国际标准化原则制定的。

1.1 This practice covers general procedures to be used when exposing nonmetallic materials in accelerated test devices that use laboratory light sources. Detailed information regarding procedures to be used for specific devices are found in standards describing the particular device being used. For example, detailed information covering exposures in devices that use open flame carbon arc, enclosed carbon arc, xenon arc, and fluorescent UV light source are found in Practices G152, G153, G154, and G155 respectively.

NOTE 1: 
Carbon-arc, xenon arc, and fluorescent UV exposures were also described in Practices G23, G26, and G53 which referred to very specific equipment designs. Practices G152, G153, and G154, and G155 are performance based standards that replace Practices G23, G26, and G53.

1.2 This practice also describes general performance requirements for devices used for exposing nonmetallic materials to laboratory light sources. This information is intended primarily for producers of laboratory accelerated exposure devices.

1.3 This practice provides information on the use and interpretation of data from accelerated exposure tests. Specific information about methods for determining the property of a nonmetallic material before and after exposure are found in standards describing the method used to measure each property. Information regarding the reporting of results from exposure testing of plastic materials is described in Practice D5870.

NOTE 2:Guide G141 provides information for addressing variability in exposure testing of nonmetallic materials. Guide G169 provides information for application of statistics to exposure test results.

NOTE 3:This standard is technically equivalent to ISO?4892, Part 1.

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.
