Coatings on metal fasteners - Specification for phosphate or phosphate and oil coatings Ingestion-build-52208 with electrically driven compressors for1 Scope This Part of BS 7371 specifies requirements for phosphate or phosphate and oil coatings on metal fasteners and accessories, applied by immersion or spraying. NOTE 1 Phosphate coatings are primarily intended for application to ferrous, zinc or zinc alloy fasteners. NOTE 2 Phosphate coatings can be used as an undercoat to improve the corrosion resistance and adhesion of a subsequently applied top coat (e. g. organic coating). NOTE 3 Phosphate
