NF A91-124-2002 specifies the adhesion test method for hot-dip galvanizing in metal platings. This standard evaluates the durability and disbonding performance of platings by measuring the adhesion between hot-dip galvanizing layers and substrates. Hot-dip galvanizing is widely used in the anti-corrosion treatment of steel materials, and adhesion is a key factor to ensure that platings do not peeling and fail during use. This test method provides manufacturers with a scientific and effective means to ensure the Stability and long-term protection effect of hot-dip galvanizing layers in different environments. It is widely used in construction, automotive, marine and other industries to help improve the mass and service life of products.
