Durable – reliable – safe
Everyday life without plastic products is impossible. Therefore it's important that they fulfill their tasks as good as perspected. We are happy to perform the necessary quality assurance tests for this purpose.
Tested safety
Safety and outstanding quality are good sales arguments for your products. In our accredited test laboratory, we test and certify a wide range of different plastic products using numerous test methods.
Confidence bonus for certified products
Test seals increase confidence in a product and the associated tests for quality assurance. Our accredited test laboratory will also test and certify your products.

Testing of plastic pipe systems
The place to go for all questions concerning plastic pipes.
Our testing laboratory for Plastic Pipe Systems combines our expertise in the field of plastic piping systems across the various divisions of SKZ:
In our testing laboratories (acc. to DIN EN ISO/IEC 17025), all common tests on components for pipelines are carried out – from bursting pressure tests on micro ducts for broadband expansion to determination of ring stiffness on DN 1000 wastewater pipe.
Our inspectors visit the production sites of our customers worldwide and carry out product monitoring (acc. to DIN EN ISO/IEC 17020) for many certifiers.
Our certification body (acc. to DIN EN ISO/IEC 17065) certifies more than 150 customers according to more than 100 different standards and guidelines concerning the piping sector (e.g. according to our SKZ HR specifications for tests and inspection).
