中文名稱(chēng):油漆及相關(guān)涂料熒光紫外線冷凝曝露測(cè)試的標(biāo)準(zhǔn)測(cè)試方法
英文名稱(chēng):Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings
1.1本實(shí)施規(guī)程包括根據(jù)實(shí)施規(guī)程G151和G154在熒光紫外線和冷凝裝置中進(jìn)行的涂層和相關(guān)產(chǎn)品加速暴露試驗(yàn)的試驗(yàn)條件選擇。本規(guī)程還包括試樣的制備和試驗(yàn)結(jié)果的評(píng)估。表1描述了常用的試驗(yàn)條件。
注1:本實(shí)施規(guī)程的先前版本引用了實(shí)施規(guī)程G53中描述的熒光UV裝置,其描述了非常具體的設(shè)備設(shè)計(jì)。規(guī)程G53已撤銷(xiāo),并由規(guī)程G151代替,規(guī)程G151描述了使用實(shí)驗(yàn)室光源的所有曝光裝置的性能標(biāo)準(zhǔn),規(guī)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還描述了涂料和涂層的熒光紫外線冷凝暴露。
1.2以國(guó)際單位制表示的數(shù)值視為標(biāo)準(zhǔn)。括號(hào)中給出的值僅供參考。
1.3本標(biāo)準(zhǔn)無(wú)意解決與其使用相關(guān)的所有安全問(wèn)題(如有)。本標(biāo)準(zhǔn)的使用者有責(zé)任建立適當(dāng)?shù)陌踩⒔】岛铜h(huán)境實(shí)踐,并在使用前確定監(jiān)管限制的適用性。
1.4本國(guó)際標(biāo)準(zhǔn)是根據(jù)世界貿(mào)易組織技術(shù)性貿(mào)易壁壘(TBT)委員會(huì)發(fā)布的《關(guān)于制定國(guó)際標(biāo)準(zhǔn)、指南和建議的原則的決定》中確立的國(guó)際公認(rèn)標(biāo)準(zhǔn)化原則制定的。
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 Practice G53 has been withdrawn and replaced by Practice G151, which describes performance criteria for all exposure devices that use laboratory light sources, and by Practice G154, which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.
