Testing welded joints according to applicable standards

During the construction of foil structures, the quality of welded joints is crucial. The adhesion of the welding surface determines the reliability and service life of the construction. By testing welded joints according to applicable standards and guidelines, you gain insight into the quality and reliability of the welds.

The quality of welded joints can be assured by performing checks before, during and after the welding process. By performing these checks and tests, you reduce risks and ensure that constructions meet the set requirements and standards.

Important control moments are:

  • Checking preparations and welding parameters before starting the welding process
  • Control during the welding process
  • Visual and mechanical examination of fabricated welds after the welding process

From sampling to certification

Normec has laboratory facilities for the preparation and testing of plastic film and welded joints. Our specialists perform both field welds on a sample basis and test welds according to the applicable DIN guidelines and ISO standards.

During the trials, various mechanical tests are carried out to assess the strength and quality of the welded joint. Based on the test results, you gain insight into the quality of the weld and know whether it meets the set standards and specifications.

We guide you through the entire process: from sampling and preparation to testing, reporting and possible certification.

Mechanical testing of welded joints

Mechanical testing of welded joints gives you certainty about the quality and reliability of your film constructions.

Normec carries out tests according to the following standards, among others:

  • NEN-EN-ISO 527 - Tensile testing of plastic films and welded joints.
  • NEN-EN-ISO 8256 - Tensile-strength test of plastic film and welded joints
  • NEN-EN 12316-2 - Peel-off test for plastic welding joints
  • EN 14576 - Constant Load Test plastic welded joints
  • Protocols plastic geomembranes UIT 83 and UIT 84 (NEN)

This will provide you with the following, among other things:

  • Insight into the strength and quality of welded joints
  • Demonstrate compliance with standards and guidelines
  • Reduction of risks and failure costs
  • Reliable reports for clients and supervisors
  • Support with quality assurance and certification

Frequently Asked Questions

Testing welded joints gives you insight into the quality, strength and reliability of the weld. This helps to reduce risk and meet client standards and requirements.

Welded joints are tested according to various standards, such as ISO, NEN, DIN and ASTM standards. Which standard is applied depends on the material and application.

A peel-off test is a test that measures the amount of force required to pull a weld joint loose. This assesses the quality of the weld.

In a tensile test, the material or welded joint is subjected to a tensile load until it breaks. This determines the strength and elongation of the material or weld.

Yes, Normec can test field welds on a sample basis to verify that the welds meet the specified requirements in practice.

Yes, after the tests you will receive a report with the test results and assessment according to the applicable standards.
