The Nordic Quality Mark for plastic pipes

By specifying Nordic Poly Mark or a corresponding requirement level it is assured that:

  • The products will have a quality level which corresponds to what earlier have been used in the Nordic countries.
  • The manufacturer is checking his production on a regular basis and keeping records of his internal testing.
  • An independent testing institute will suport the testing personel by the manufacturer and perform audit testing at random once a year.

In January 2012 the Insta-Cert member companies have issued more than 200 Nordic Poly Mark licenses to manufacturers from more than XX countries.

Further information is presented at: www.nordicpolymark.com. and www.insta-cert.net.
