Scope

1.1

This standard covers asphalt core boards intended for use as a substrate to receive an asphalt-based, low-slope roof membrane system (built-up or modified-bitumen).  In such systems, the roofing membrane may be adhered with hot asphalt or cold-applied adhesive or heat welded to asphalt core board or mechanically attached through asphalt core board to the structural deck. This standard applies to asphalt core boards installed horizontally and vertically (on flashings and parapets). 

1.2

This standard does not specify requirements for the use of asphalt core board in protecting a substrate.

This standard does not address asphalt based protection boards used in waterproofing; for information on these products, refer to ASTM Standard Specification D6506.

Asphalt core boards addressed in this standard are not intended as substrates for vertical flashings unless fully supported, in a low-slope roofing system.

1.3

The values given in SI (metric) units are the standard.  The values given in parentheses are for information only.
