Weight [Mass] of Coating on Iron and Steel Articles with Zinc or Zinc-Alloy Coatings

ASTM A90

This test method provides a standard method for determining the weight [mass] of coating for comparison with specification requirements. A coating of zinc on iron or steel articles provides protection against corrosion. As the protection is provided by sacrificial loss of zinc, the degree of protection is proportional to the weight [mass] of zinc coating. Specifications for zinc-coated articles frequently provide for different classes of coating so that the purchaser can select the coating weight [mass] most suitable to his or her needs.

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM A90 for Weight [Mass] of Coating on Iron and Steel Articles with Zinc or Zinc-Alloy Coatings. Contact us to learn more.
