Corrosion testing of electronic units (NT TR 590)

NT TR 590

  • Nowadays, the demand for better and reliable products is high, whereas the time between the idea of a product and the production decreases. This is especially the case for products containing electronics, which are part of our everyday life. Because electronic products are submitted to all kinds of environments, especially corrosive environments, the demand for adapted corrosion testing methods assuring their well functioning after years of use is needed.

Korrosjonspåvirkning fra brannimpregnert trevirke - En ringtest og ny prøvemetode (NT TR 546)

NT TR 546

  • En akselerert metode for å vurdere korrosjonspåvirkningen fra brannimpregnert tre på festemidler er testet ut ved å eksponere prøvene i et fuktig klima (RF = 90 %) ved 27 °C og sammenlikne med korrosjon i utendørs eksponering i ett år.

Methods for test of reinforcement material properties based on mix of stainless steel and carbon steel (NT TR 528)

NT TR 528

  • The project describes methods for testing of corrosion resistance and mechanical properties of reinforcing steel consisting of stainless steel and carbon steel. Methods for testing of mechanical properties (tensile strength and fatigue) are based on the existing standards for traditional carbon steel reinforcement, NS 3420, NS 3575, NS-EN 288-3, NS 480, NS 3473 and ASTM E 739-1.

Protective paint coatings on steel: Accelerated corrosion test in high humidity air containing small amounts of sulphur dioxide (NT BUILD 377)

NT BUILD 377

  • This method specifies the test equipment, preparation of test specimens and the procedure for accelerated corrosion tests on protective paint coatings on steel. The corrosion test is conducted in an artificial atmosphere of air containing 1 ppm sulphur dioxide. Exposure takes place at a constant relative humidity of 95 % and at a constant temperature of 23 ºC.
