DIN 55634-2:2017-09

This standard applies for the protection from corrosion of supporting thin-walled building components made from steel, the nominal sheet thickness of which is up to 3 mm and which are subjected to atmospheric corrosion stress. The building components are manufactured from steel coated by zinc (hot-dip galvanizing) or zinc alloys and having afterwards either coil-coated or coated by piece-work coating at plant or site, using metallic coatings, organic coatings or metallic and organic coatings (duplex systems). Requirements and test procedures are specified in DIN 55634-1 (currently draft Standard). In this Part 2 surveillance and certification requirements are specified.
