Historical Standard: ASTM D7056-04 Standard Test Method for Determining the Tensile Shear Strength of Pre-Fabricated Bituminous Geomembrane Seams
SUPERSEDED (see Active link, below)
ASTM D7056
1. Scope
1.1 This test method presents the procedures used for determining the quality of prefabricated bituminous geomembrane (PBGM) bonded seams subjected to a shear test. It describes a destructive quality control test used to determine the integrity of PBGM seams.
1.2 This test procedure is intended for PBGM only.
1.3 The type of thermal field seaming technique used to construct PBGM seams include the following.
1.3.1 Torch-onThis technique melts two PBGM surfaces to be seamed by running a flame from a propane torch between them. Pressure is applied on the top or bottom, or both PBGM, forcing together both surfaces to form a continuous bond.
1.3.2 Hot AirThis technique introduces high-temperature air or gas between two PBGM surfaces to facilitate melting. Pressure is applied on the top or bottom, or both PBGM, forcing together both surfaces to form a continuous bond.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
