ASTM D6163/D6163M-21 PDF Download

The ASTM D6163/D6163M-21 standard is a specification for styrene butadiene styrene (SBS) modified bituminous sheet materials that use glass fiber reinforcements. These materials are used for the fabrication of multiple ply roofing and waterproofing membranes. The standard focuses on specifying the minimum properties and tests that the sheet materials should adhere to.

The standard covers two grades of materials: Grade G, which has a granule surface, and Grade S, which has a smooth surface. The sheet materials are modified with SBS thermoplastic elastomer to improve their performance.

It's important to note that this standard is a material specification only 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, and uplift resistance are beyond the scope of this standard.

The specified tests and property limits outlined in the standard include peak load before and after heat conditioning, elongation at peak load, tear strength, low temperature flexibility, dimensional stability, compound stability at specified temperatures, and granule embedment. These properties are used to characterize and evaluate the sheet materials.
