Coating tests

Coating testing laboratory

We have many years of experience in testing standard coating materials

We test organic and inorganic coatings as well as temporary corrosion protectives to relevant standards and/or customer requirements. We also conduct comprehensive qualification tests. In the testing of organic pipe coatings, we specialize in:

  • 3-layer polyolefin coatings (for instance in accordance with ISO 21809-1, DIN 30670, DIN 30678 and CSA Z245.21)
  • 1-layer FBE coatings (for instance in accordance with ISO 21809-2 and CSA Z245.20)
  • Field joint coatings (for instance in accordance with ISO 21809-3 and DIN EN 12068
  • Internal pipe coatings (for instance in accordance with ISO 15741, DIN EN 10301 and API RP 5L2)

Natural weathering tests, salt spray tests (ISO 9227) and artificial climates (ISO 6270-2) can be used to test corrosion resistance.

In our autoclave laboratory, coating materials can be tested under extreme conditions, such as elevated pressure, elevated temperature and exposure to corrosive gases.

Testing of organic coatings for industrial goods and vehicles

We test the properties of paints and films from continuous coil coating processes or automotive painting operations.

We test according to the following methods and/or standards:
