Overview

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.

Key Topics

• 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:

  • Test medium (e.g., water, air)
  • Test pressure (up to twice nominal pipe pressure)
  • Test duration and temperature
  • Angle of deflection (degrees)
  • Free length of pipe between socket and seal ring groove

• Apparatus and Setup
  Includes a rigid framework with fixing devices, pressure control and measurement systems, and means to apply angular deflection.

• Test Procedure

  • Prepare test pieces in accordance with manufacturer specifications.
  • Condition the assembly to ensure temperature stabilization.
  • Apply internal pressure while angularly deflecting the pipe.
  • Monitor for leakage over the test duration.

• Results and Reporting
  Detailed test reports must document:

  • Standards referenced
  • Pipe and fitting identification
  • Test conditions (pressure, temperature, angle, duration)
  • Observed leakages, if any, with corresponding pressures

Applications

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.
