1.1 This guide describes the selection of test methods and criteria to be used to simulate the aging of concealed air and water-resistive barriers for above grade walls. 1.1.1 The sequence of test methods selected is desired to simulate exposure during the construction process followed by aging that occurs during the service life of the barrier. 1.2 This guide does not provide for a conclusion within itself but is for use in conjunction with appearance or physical property tests to follow accelerated exposure. 1.3 This standard does not address the simulation of extreme natural or man-made events such as hurricanes, blast, etc.
The type and number of air barriers and water-resistive barriers is growing in the market, and although there are standards efforts to define the performance of these materials, methods to evaluate the long term durability of these materials have not been developed.
