ASTM D904標(biāo)準(zhǔn)介紹

ASTM D904規(guī)定了膠接接頭(至少有一個(gè)玻璃或透明粘接)紫外線(xiàn)(UV)光老化(有水循環(huán)或無(wú)水循環(huán))的基本原則和操作程序，使用熒光紫外線(xiàn)(見(jiàn)方法A)或氙弧光源(見(jiàn)方法B)?，F(xiàn)行標(biāo)準(zhǔn)為版本為2013年復(fù)審的ASTM D904 - 99（2013）。

1. Scope

1.1 This practice covers the basic principles and operating procedures for ultraviolet (UV) light aging (with or without water) of adhesive bonded joints having at least one glass or transparent adherend, using fluorescent UV (see Method A) or xenon-arc light sources (see Method B).

1.2 This practice is limited to the apparatus for obtaining, measuring, and controlling the aging conditions, and to the procedures for exposure. Sample preparation, strength, test conditions, and evaluation of the results are described in other ASTM test methods or specifications.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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