ASTM WK93199
New Specification for Self-Adhering, Plastomeric Modified Bituminous Sheets used in Low Slope Roofing
1. Scope
This specification covers prefabricated, self-adhesive, modified bituminous sheet materials reinforced with one the following reinforcement types: 1) Glass Fiber 2) Polyester fabric. The prefabricated sheet utilizes APP plastomer as the primary modifier and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes. The product may or may not have granule surfacing but has an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet.Keywords

In the absence of a Spec for Self-Adhering Modified Bituminous sheets, these sheet types are being evaluated under ASTM D6222, D6509 or D6223. None of these standards address the adhesive properties inherent solely to SA Material. ASTM D1970 is utilized for SA base sheets and does address adhesion properties. But this spec does not cover potential Self-Adhering Cap sheets
