Test/inspection body

The WPK Austria GmbH as a state accredited inspection body according to EN ISO/IEC 17020 carries out acceptances and recurring inspections for complete plants as well as individual components and assemblies.

We inspect ropeways and drag lifts, hydroelectric power plants and lifting equipment (lifts, lifting tables, stair lifts) and are also accredited as an inspection body for summer toboggan runs and flying constructions.

Since 2018 we have also been accredited as an inspection body according to ÖNORM B 5050 and our certified inspectors carry out pressure tests on water-carrying pipelines of hydroelectric power plants and snow-making systems.

The speciality of our testing laboratory accredited according to EN ISO/IEC 17025 is non-destructive testing (NDT) in all relevant fields. As an accredited inspection body, we also advise on the application of a suitable test procedure, draw up test specifications, take over quality assurance and carry out the corresponding non-destructive tests at the customer's premises or in our test laboratory.

Pressure tests according to ÖNORM B 5050

Water-carrying pipelines of new and existing hydroelectric power plants and snow-making systems must be examined for leaks and stability by means of a pressure test in accordance with ÖNORM B 5050:2015. The application of this relatively new standard ensures a long-term, safe and efficient operation of the pipeline and thus provides both the operator and the manufacturer with a significant added value, which contributes in particular to securing the investment.

The pressure test according to ÖNORM B 5050 may only be carried out by certified persons with the appropriate expertise or by an inspection or testing body accredited according to ÖNORM B 5050, such as WPK Austria.

Our services at a glance:

  • Performance of pressure tests as inspection body according to ÖNORM B 5050
  • Testing by certified testers according to ÖNORM B 5050
  • Execution of the test with own, certified test equipment
  • Preparation of test and inspection reports
  • many years of experience in the acceptance and periodic inspection of hydropower plants

Welder's examination and welding supervision

To ensure the quality of welding work, many sets of rules and regulations, e.g. ÖNORM EN 1090, the Machinery Directive, the Pressure Equipment Directive, etc., require the use of certified welders.

In addition, many clients of welding work also require sufficiently qualified personnel within the framework of product liability and quality assurance. ÖNORM EN 1090, for example, requires the use of certified welders, operators, welding supervisors and inspectors for all load-bearing components from design class 1 (EXC 1) upwards.

A welder's qualification test according to ÖNORM EN ISO 9606-1 remains valid for 3 years, provided that the welder is regularly engaged in welding work in the applicable test area.

The following services are offered by the welding engineers of WPK Austria:

  • Welding qualification tests according to ÖNORM EN ISO 9606-1 (fusion welding of steels) for various welding procedures
  • Operator test according to ÖNORM EN ISO 14732
  • Welding supervision according to ÖNORM EN ISO 14731 with own welding engineers (IWE) - also for external welding supervision
  • Monitoring of the process and work samples
  • Testing of samples within the accredited testing laboratory (VT, UT, MT, PT, break)
