EN ISO 1461 = functional requirements zinc coating
EN 14713-1 and 2: structural requirements for safety during galvanization
Zinc melt consists of 98% pure zinc
Minimum layer thicknesses according to tables
Relevant surfaces (primary sight sides) should be assessed at a distance of at least 1 meter with the naked eye
Dark and light spots are allowed
Zinc greenhouses are permitted provided they do not affect corrosion resistance or the purpose of use
Sharp points, if they can cause injury and are not the result of over-rolling, should be removed
Stains due to zinc corrosion are allowed as long as coating meets minimum layer thickness
Effects due to intermittent welding are permitted
Thickening is permitted if it does not affect the purpose of use
Unevenness on the surface is permissible
Relevant surfaces should be free of 1. Thickening in the form of blisters (raised areas without solid metal underneath) 2. Roughness 3. Ungalvanized areas
Flux residues are permitted provided they do not affect corrosion resistance or purpose of use.
Rejected items may be touched up or re-galvanized in accordance with the standard.
