ASTM D6223/D6223M-21 PDF Download

The ASTM D6223/D6223M-21 standard is a specification for atactic polypropylene (APP) modified bituminous sheet materials. These sheet materials are used in the fabrication of multiple ply roofing and waterproofing membranes. The sheet materials are reinforced with a combination of polyester fabric and glass fiber and may have a granule or smooth surface.

This standard establishes the minimum properties and tests required for the sheet materials. Some of the tests include peak load before and after heat conditioning, elongation at peak load, tear strength, low temperature flexibility, dimensional stability, compound stability, granule embedment, water absorption, moisture content, and low temperature unrolling.

It's important to note that this specification is focused on the material properties of the sheet materials and does not address issues related to specific roof constructions or application techniques. Factors such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and the need for field applied coatings are outside the scope of this standard.
