Last updated: 05/06/2020

The Laboratory of Materials and Coatings (LMR) of LNEG is a specialized center in the fields of corrosion, degradation and anticorrosive protection of materials.

Within the natural and artificial aging of materials and coatings, the following tests can be carried out:

  • Natural exposure*
  • Corrosivity of atmospheres – Classification, determination and estimation *
  • Determination of resistance to water and other liquids*
  • Determination of resistance to artificial seawater*
  • Determination of resistance to cathodic delamination *
  • Determination of resistance to exposure in a chamber with Xenon arc*
  • Determination of resistance to humid atmospheres containing different polluting gases (SO2 and / or NO2) *
  • Determination of resistance to humidity and temperature *
  • Determination of resistance to cyclic corrosion conditions *
  • Neutral salt spray test (NSS)
  • Acetic acid salt spray test (AASS)*
  • Copper-acetic acid salt spray test (CASS)*
  • UV resistance and condensation test*
  • Resistance to humidity and drying cycles *
  • Thermal shock test *

* Test not included in the scope of accreditation.
