Plastics piping systems - Elastomeric-sealing-ring-type socket joints for use with thermoplastic pressure pipes - Test method for leaktightness under internal pressure and with angular deflection (ISO 13845:2015)
ISO 13845:2015 specifies a method for testing the leak tightness under internal pressure with angular deflection of assembled joints between elastomeric-sealing-ring-type sockets made of plastic or metal and plastic pressure pipes.
EN ISO 13845:2015 is an international standard developed by CEN and ISO that specifies a test method for leaktightness of elastomeric-sealing-ring-type socket joints used with thermoplastic pressure pipes. The focus of this standard is on assessing the joint's integrity under internal pressure combined with angular deflection. This ensures that socket joints maintain a secure, leakproof connection even when subjected to bending forces and pressure variations typical in real-world piping installations.
This standard is essential for manufacturers, testers, and engineers involved in plastics piping systems, particularly those using elastomeric sealing rings made of plastic or metal components combined with thermoplastic pressure pipes. EN ISO 13845:2015 supersedes the previous edition EN ISO 13845:2000, offering updated test procedures that apply to a wider range of materials, pipe dimensions, and operational conditions.
Scope and Application Applies to testing assembled joints between elastomeric sealing ring sockets and thermoplastic pressure pipes under internal hydraulic pressure plus angular deflection.
Test Principle The joint assembly is mounted in a test apparatus where it experiences specified internal pressure while the pipe is deflected at a defined angle. The test checks for leaks during the test duration.
Test Parameters Important parameters that influence testing include:
Apparatus and Setup Includes a rigid framework with fixing devices, pressure control and measurement systems, and means to apply angular deflection.

EN ISO 13845:2015 is widely used in:
Manufacturing Quality Control Ensures that elastomeric-sealing-ring-type socket joints fulfill safety and performance criteria before market release.
Product Certification and Standards Compliance Compliance with this standard supports product certification processes and regulatory requirements for pressure piping systems.
System Design and Engineering Enables designers to specify joints that maintain leaktightness under operational stresses involving pressure and bending.
Construction and Installation Testing Verifies joint performance under field conditions that may impose both pressure fluctuations and pipe deflections.
This standard is critical for industries such as water supply, gas distribution, chemical processing, and wastewater management, where combining secure joints with flexibility is vital.
