ASTM D7349/D7349M-15 (R2019) PDF Download

The ASTM D7349/D7349M-15 (R2019) standard is a qualitative test method that determines the ability of asphalt-based roofing or waterproofing materials to seal around fasteners and prevent the transmission of liquid water through the material at the penetration point. This test is important because in certain construction processes, the penetration of fasteners through roofing or waterproofing materials is necessary, and it is expected that the materials will effectively limit the migration of water at the interface between the fasteners and the material.

The standard provides a standardized means to evaluate the capability of a material to seal around a fastener by subjecting it to defined conditions. It is intended for adoption by ASTM or other consensus-based roofing and waterproofing product specifications. The performance of this test method can also be evaluated after subjecting the product to conditioning that simulates environmental stresses and strains.

It's important to note that the text of this standard includes explanatory notes and footnotes, but these should not be considered as requirements of the standard, excluding those in tables and figures.
