ASTM G151-19適用范圍

1.1本實施規程涵蓋了在使用實驗室光源的加速試驗裝置中暴露非金屬材料時使用的一般程序。有關用于特定設備的程序的詳細信息，請參見描述所用特定設備的標準。例如，關于使用明火碳弧、封閉碳弧、氙弧和熒光紫外光源的裝置中的曝光的詳細信息分別見實施規程G152、G153、G154和G155。

注1：實踐G23、G26和G53中也描述了碳弧、氙弧和熒光紫外線曝光，這些實踐涉及非常具體的設備設計。規程G152、G153、G154和G155是基于性能的標準，取代規程G23、G26和G53。

1.2本實施規程還描述了用于將非金屬材料暴露于實驗室光源的裝置的一般性能要求。此信息主要用于實驗室加速曝光設備的生產商。

1.3本規程提供了加速暴露試驗數據的使用和解釋信息。關于非金屬材料暴露前后性能測定方法的具體信息，見描述測量每種性能方法的標準。規程D5870中描述了有關塑料材料暴露試驗結果報告的信息。

注2：指南G141提供了解決非金屬材料暴露試驗可變性的信息。指南G169提供了暴露試驗結果統計應用的信息。

注3：本標準在技術上等同于ISO?4892第1部分。

1.4本標準無意解決與其使用相關的所有安全問題（如有）。本標準的使用者有責任建立適當的安全、健康和環境實踐，并在使用前確定監管限制的適用性。

1.5本國際標準是根據世界貿易組織技術性貿易壁壘（TBT）委員會發布的《關于制定國際標準、指南和建議的原則的決定》中確立的國際公認標準化原則制定的。

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.
