Crush Decohesion Testing of Electrofusion Couplers
CRUSH DECOHESION TESTING OF ELECTROFUSION COUPLERS to ISO 13955
The purpose of this test is to assess the cohesion of the pipe and electrofusion coupler assembly by submitting a force and crushing the sample. Crush testing of electrofusion couplers is an essential method to verify the integrity of electrofusion welds. This helps to identify poor quality production welds at the earliest stage and avoid costly errors.
