        ASTM D4799-00簡介

        瀝青材料(熒光紫外線、噴淋及冷凝法)加速老化測試條件和測試程序的標準測試方法:

        本測試方法描述了根據G151和G154瀝青屋面和防水材料(最低軟化點約95°) 的做法進行熒光紫外線和冷凝曝露測試的測試條件和程序。

        ASTM D4799-00英文簡介

        1. Scope

        1.1 This test method covers the test conditions and procedures that are applicable when Practice G53 is employed for the exposure of bituminous roofing and waterproofing materials having a minimum softening point of approximately 200°F (95°C) as determined by Test Method D36.

        1.2 The values stated in inch-pound units are to be regarded as the standard.

        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.
