ASTM G151-19簡(jiǎn)介

【翁開爾是美國Q-LAB中國代理商,40年專業(yè)代理美國Q-LAB系列產(chǎn)品,提供行業(yè)標(biāo)準(zhǔn)解讀和上門培訓(xùn)】

ASTM G151是使用實(shí)驗(yàn)室光源加速測(cè)試設(shè)備對(duì)非金屬材料進(jìn)行曝露的測(cè)試方法:

中文名:ASTM G151-2019 非金屬材料在使用實(shí)驗(yàn)室光源裝置進(jìn)行加速測(cè)試中曝光測(cè)試的操作規(guī)程

英文名稱:Standard Practice for Exposing Nonmetallic Materials in Accelerated Test Devices that Use Laboratory Light Sources

發(fā)行時(shí)間:2019-1-1

ASTM G151-19

ASTM G151-19適用范圍

1.1本實(shí)施規(guī)程涵蓋了在使用實(shí)驗(yàn)室光源的加速試驗(yàn)裝置中暴露非金屬材料時(shí)使用的一般程序。有關(guān)用于特定設(shè)備的程序的詳細(xì)信息,請(qǐng)參見描述所用特定設(shè)備的標(biāo)準(zhǔn)。例如,關(guān)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(xì)信息分別見實(shí)施規(guī)程G152、G153、G154和G155。

注1:實(shí)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(shí)踐涉及非常具體的設(shè)備設(shè)計(jì)。規(guī)程G152、G153、G154和G155是基于性能的標(biāo)準(zhǔn),取代規(guī)程G23、G26和G53。

1.2本實(shí)施規(guī)程還描述了用于將非金屬材料暴露于實(shí)驗(yàn)室光源的裝置的一般性能要求。此信息主要用于實(shí)驗(yàn)室加速曝光設(shè)備的生產(chǎn)商。

1.3本規(guī)程提供了加速暴露試驗(yàn)數(shù)據(jù)的使用和解釋信息。關(guān)于非金屬材料暴露前后性能測(cè)定方法的具體信息,見描述測(cè)量每種性能方法的標(biāo)準(zhǔn)。規(guī)程D5870中描述了有關(guān)塑料材料暴露試驗(yàn)結(jié)果報(bào)告的信息。

注2:指南G141提供了解決非金屬材料暴露試驗(yàn)可變性的信息。指南G169提供了暴露試驗(yàn)結(jié)果統(tǒng)計(jì)應(yīng)用的信息。

注3:本標(biāo)準(zhǔn)在技術(shù)上等同于ISO?4892第1部分。

1.4本標(biāo)準(zhǔn)無意解決與其使用相關(guān)的所有安全問題(如有)。本標(biāo)準(zhǔn)的使用者有責(zé)任建立適當(dāng)?shù)陌踩?、健康和環(huán)境實(shí)踐,并在使用前確定監(jiān)管限制的適用性。

1.5本國際標(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)于制定國際標(biāo)準(zhǔn)、指南和建議的原則的決定》中確立的標(biāo)準(zhǔn)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.
