DIN EN ISO 13846 – End-load-bearing and Non-end-load-bearing Assemblies and Joints for Thermoplastics Pressure Piping – Test Method for Long-term Leaktightness Under Internal Water Pressure – Testing Equipment
2 Principle The test simulates expansion of the joint area due to creep. This is related to the permissible working conditions for 50 years and based on the properties of the components assembled. The leaktightness of the joint(s) is tested as an assembly comprising either: a) at least one fitting joined to pipes; or b)…
