Abstract

This document specifies methods for testing the resistance to sustained longitudinal tensile loading (longitudinal stress-rupture) of uniaxial plastic pipe/pipe or pipe/fitting or fitting/fitting assemblies using hydraulic pressure at a given temperature. This document is applicable to pipe assemblies with electrofusion or butt fusion joints. The methods accommodate water-in-water, water-in-air, and liquid-in-liquid tests. Method A uses no external hoop expansion restraint (specifically designed test piece). Method B uses external hoop expansion restraint (metal end caps or circumferential (ring) clamps).
