GB/T 19808-2005 Plastics pipes and fittings - Peel decohesion test for polyethylene (PE) electrofusion assemblies of nominal outside diameter greater than or equal to 90 mm
1 Scope
This standard describes a peel test method for determining the decohesive resistance of polyethylene electrofusion socket assemblies for use in the distribution of fluids.
This standard is applicable to assemblies with nominal outside diameters greater than or equal to 90 mm.

The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this standard. However parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
GB/T 19807 Plastics pipes and fittings - Preparation of test piece assemblies between a polyethylene (PE) pipe and an electrofusion fitting (GB/T 19807-2005; ISO 11413: 1996, MOD)
3 Principle
The purpose of the test is to assess the cohesion of a PE pipe/electrofusion socket assembly by examination of the decohesion of the assembly by tensile stressing of a strip test piece under conditions which cause progressive peeling of the fused interface. The test is conducted at 23 °C ± 2 °C.
The decohesive strength of the assembly is characterized by the nature of the failure in the tube wall, the fitting wall or the plane of the fused material and by the percentage decohesion.
