ISO 12944 is in 1998 ingevoerd als Europese en Internationale standard als de hoogste wereldwijde kwaliteitsstandaard voor het beschermen van ijzeren constructies tegen corrosie. ISO 12944 heeft betrekking op coating-systemen voor applicatie op blank staal, heet gegalvaniseerd staal en stalen oppervlakken met thermisch gespoten zink coating. Een onafhankelijk laboratiorum heeft de twee belangrijkste 2K coating-systemen van Selemix getoetst aan de Internationale ISO 12944 standaard en heeft ze ingedeeld in de corrosie- en duurzaamheidscategorie van ISO 12944-6 (Laboratory performance test methods). |
