Organization: DIN
Publication Date: 1 July 1997
Status: active
Page Count: 4
ICS Code (Welded joints and welds): 25.160.40
scope:

To assess the performance of welded assemblies, made from thermoplastics materials - especially their long term strength - the tensile creep test has proved its worth in conjunction with other tests.

There is a lot of experience with this test for the polyolefine materials PE and PP (polyethylene and polypropylene). First experiences with this test are also available for PVC-U (polyvinyl chloride without plasticizer and PVDF (polyvinylidene fluoride).

Tensile creep tests are applicable to sheets, pipes and profiles. The relevant directive for the application field "Membranes in geotechnical and hydraulic application" is DVS 2226-4.

The long term tensile welding factors and the fracture surfaces give evidence about the quality of the welded joint. The test results can be used when designing welded semi-finished products under static load.
