ASTM D6298/D6298M-16 PDF Download

The ASTM D6298/D6298M-16 standard is a specification for fiberglass reinforced bituminous sheet materials that have been modified with styrene-butadiene-styrene (SBS) thermoplastic elastomer and have a factory-applied continuous metal foil surface. These materials are primarily used for fabricating multiple ply roofing and waterproofing membranes and flashings.

This specification focuses on the material properties of the fiberglass reinforced SBS modified bituminous sheets with a metal surface. It does not address specific roof constructions or application techniques. The purpose of this specification is to establish minimum properties for these materials.

The standard defines various tests and property limits that these materials must conform to. These include measurements of thickness, net mass per unit, back surface coating thickness, peak load value, elongation at peak load, ultimate elongation, tensile-tear strength, low-temperature flexibility, dimensional stability, compound stability, cyclic thermal shock, water absorption, and moisture content.

It is important to note that this specification does not cover roof system design criteria, such as fire resistance, field strength, impact/puncture resistance, material compatibility, and uplift resistance. These factors are considered beyond the scope of this specification.
