EN 12814-6:2000 - Overview

EN 12814-6:2000 (CEN) defines the procedure for the low temperature tensile test of welded joints in thermoplastic semi-finished products. The standard specifies how to select, dimension, sample and prepare test specimens and the general conditions for carrying out a tensile test perpendicular to the weld. The objective is to determine the low temperature tensile welding factor and to assess joint ductility and work quality using the fracture surface appearance.

Key topics and requirements

  • Scope and purpose - Test method focused on welded joints of thermoplastic semi-finished products under low-temperature tensile loading.
  • Specimen selection and dimensions - Rules for sampling from welded assemblies and preparing specimens representative of the welded area (the standard specifies required dimensions and geometry).
  • Test orientation - Tensile test performed perpendicular to the weld to evaluate strength and ductility across the fusion line.
  • Test conditions - Defined low-temperature environment and tensile conditions are required (see standard text for specific conditions).
  • Results and interpretation - Determination of a low temperature tensile welding factor; fracture surface appearance is used to judge ductility and weld quality.
  • Complementary testing - The low temperature tensile test is intended to be used alongside other methods (for example bend tests, tensile creep, macro-examination) to form a full assessment of welded assembly performance.

Practical applications

  • Quality control and production inspection - Verify that welded joints meet low-temperature performance criteria before product release.
  • Welding procedure and personnel qualification - Support qualification of welding processes and operators by demonstrating joint behavior at low temperatures.
  • Material selection and joint design - Inform decisions about thermoplastic grades and joint geometries where low-temperature performance is critical.
  • Failure analysis and R&D - Use tensile welding factor and fracture morphology to investigate failures or to optimize welding parameters and materials.

Who should use this standard

  • Welding engineers and fabricators working with thermoplastics
  • Materials and polymer engineers responsible for joint integrity
  • Quality assurance/quality control (QA/QC) laboratories
  • Certification bodies and testing laboratories assessing welded assemblies

Related standards

  • Other parts of the EN 12814 series covering additional test methods for welded thermoplastics assemblies
  • Relevant ISO and national standards for plastics testing and welding qualification (refer to official standards lists for exact references)
