New Practice for Standard Practice for Assessing the Durability of Mechanically Attached Sheet Air and Water-Resistive Barriers
1. Scope
This practice will be used to assess the ability of mechanically attached sheet air and water-resistive barriers to maintain serviceability upon exposure to conditioning environments intended to simulate natural weathering and aging as a means to assess the material durability.
Keywords
Durability; air barrier; water-resistive barrier; mechanically attached sheet
Rationale
The standard is needed to help evaluate the long-term performance of mechanically-attached sheet air and water-resistive barriers and will be used by manufacturers in the development of new products and by designers in assessing products for use on projects. The standard will be used by manufacturers and designers.
