        astm c1442-14標準介紹
        astm c1442主要是針對使用人工老化設備對密封劑進行測試的方法:
        本測試方法包括三種實驗室加速老化曝露程序,評估太陽光輻射、熱和潮濕對密封劑的影響。

        1. scope
        1.1 this practice covers three types of laboratory weathering exposure procedures for evaluating the effect of actinic radiation, heat, and moisture on sealants.
        1.2 the exposure sources used in the three types of artificial weathering devices are the filtered xenon arc, fluorescent ultraviolet lamps, and open flame carbon arc based on practices g155, g154, and g152, respectively.
        1.3 the values stated in si units are to be regarded as the standard. the values given in parentheses are provided for information only.
        1.4 the iso standard related to this practice is iso 11431. significant differences exist between the procedures. the iso specimens are exposed through glass and are elongated prior to examination for loss of adhesion or cohesion, or both, following exposure.
        1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
