        ASTM D4798-00標準介紹

              瀝青材料(氙弧法)加速老化測試條件和測試程序的標準測試方法:

        本測試方法規定了根據G151和G155瀝青屋面和防水材料的做法進行氙燈曝露測試的測試條件和程序。

        最小軟化點大約95℃(200°F)的瀝青屋面材料是通過測試方法D36確定。(另請參閱術語摹113。)

        ASTM D4798英文簡介

        1. Scope

        1.1 This test method covers test conditions and procedures for xenon-arc exposures according to Practice G151 and G155 for bituminous roofing and waterproofing materials having a minimum softening point of approximately 95°C (200°F) as determined by Test Method D36.(Also see Terminology G113.)

        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 and health practices and determine the applicability of regulatory limitations prior to use.
