2、the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes outdoor exposure procedures to be used as part of a test designed to determine the

Procedure A exposes specimens to outdoor weatheringwithout movement. Procedure
4、 B and Procedure C are, respectively, continuous natural and periodic manual techniques forsubjecting specimens to the combination of cyclic movement and exposure to outdoor weathering.1.3 This practice is limited to the method by which the construction seals or sealants are exposed to outdoor weath

The durabilityweatherability of seals and sealants in actualoutdoor use can be very different depending on the location, because of differences in solar radiation, moisture, temperature,pollutants, and other factors.
