Proposed Standard Supports Bend Testing to Evaluate Coating Adhesion

Printer-friendly version

ASTM International’s metallic-coated iron and steel products committee (A05) is developing a proposed standard that will demonstrate how bend testing can be used to determine how well metallic coatings adhere to steel sheet.

ASTM International member Betsy Hoppe says that the proposed test method was initiated after a steel sheet producer with a continuous hot-dip galvanizing line requested a standard that could help improve their test for metallic coating adhesion.

“Any manufacturer of sheet steel, metallic-coated by the hot-dip process, will find the proposed test method helpful in confirming the finished product has good adhesion of the metallic coating to the steel substrate,” says Hoppe. “Outsourced laboratories, regulatory bodies, or consumers of this product, could use this method to support internal quality processes to audit incoming product for similar adhesion conformance.”

All interested parties are invited to participate in the ongoing development of the proposed standard (WK63602). The task group developing the standard is particularly interested in exploring how it may apply or eventually include adhesion testing of similar metallic-coated products in different shapes or industry applications.
