發行方：STANDARD by ASTM International
中文名稱：油漆及相關塗料熒光紫外線冷凝曝露測試的標準測試方法
英文名稱：Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings
1.1本實施規程包括根據實施規程G151和G154在熒光紫外線和冷凝裝置中進行的塗層和相關產品加速暴露試驗的試驗條件選擇。本規程還包括試樣的製備和試驗結果的評估。表1描述了常用的試驗條件。
注1：本實施規程的先前版本引用了實施規程G53中描述的熒光UV裝置，其描述了非常具體的設備設計。規程G53已撤銷，並由規程G151代替，規程G151描述了使用實驗室光源的所有曝光裝置的性能標準，規程G154給出了在熒光紫外線裝置中曝光非金屬材料的要求。
注2：ISO 11507:1997還描述了塗料和塗層的熒光紫外線冷凝暴露。
1.2以國際單位製表示的數值視為標準。括號中給出的值僅供參考。
1.3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，並在使用前確定監管限製的適用性。
1.4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《關於製定國際標準、指南和建議的原則的決定》中確立的國際公認標準化原則製定的。
1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in fluorescent UV and condensation devices conducted according to Practices G151 and G154. This practice also covers the preparation of test specimens, and the evaluation of test results. Table 1 describes commonly used test conditions.
NOTE 1:Previous versions of this practice referenced fluorescent UV devices described by Practice G53, which described very specific equipment designs. Practice G53 has been withdrawn and replaced by Practice G151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G154, which gives requirements for exposing nonmetallic materials in fluorescent UV devices.
NOTE 2:ISO 11507:1997 also describes fluorescent UV-condensation exposures of paints and coatings.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
1.4 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.
