SGS specialized in the paints and protective systems validation dedicated to nautical equipments, boats and offshore structures.

Standards mainly practiced are:

  • ISO20340: Paints and varnishes - Performance requirements on paint systems for the protection of offshore structures and associated structures,
  • ISO12944- 6: Paints and varnishes - Corrosion protection of steel structures by protective paint systems - Part: 6 Performance testing laboratory.

These standards define specific aging conditions, such as aging durations but rely on neutral salt spray test methods such as ISO9227 or ISO7253 or according to the standard ISO6270 condensation test method to define the device used and the protocol.

Concerning the standard ISO20340, salt spray tests are alternated with UV photo-aging according to the standard ISO11507 to improve the simulation of natural aging.

At the end of this accelerated aging, the adhesion of the coating is validated by a tensile test according to the ISO4624 standard and various standards of assessment, like rusting, <a href="">cartier replica</a> blistering, flaking, cracking according to ISO4628 standards.
