Importance of the Standard

Polyethylene (PE) pipes and fittings are widely used in various industries, including water supply, gas distribution, and chemical processing. The integrity of these systems heavily relies on the quality of the fusion joints. The BS ISO 13956:2025 standard ensures that these joints are tested for ductility, which is a measure of their ability to deform under stress without breaking. This is crucial for preventing leaks and ensuring the longevity of the piping systems.

Detailed Evaluation Process

The standard outlines a specific tear test method to evaluate the ductility of the fusion joint interface. This involves applying a controlled force to the joint and measuring its response. The results of this test provide valuable insights into the joint's performance, helping manufacturers and engineers to make informed decisions about material selection and joint design.
