Thermal-spray standards in the United States are developed by several professional societies that include American Society for Testing and Measurement (ASTM) for test & measurements methods and composition specifications; American Welding Society (AWS) for feedstock, equipment acceptance, application process, training & certification; American Water Works Association (AWWA) for thermal-sprayed zinc as potable water tank lining; International Association of Corrosion Engineers (NACE) for corrosion protection processes and inspection; and Society of Protective Coatings (SSPC) for test & measurement methods, application specification & inspection in regards to protective coatings for the protection of steel. This paper provides information on various standards set by these bodies.

A review of selected national and international thermal spraying guides and specifications for the preservation of steel and reinforced concrete using thermal spray coating of aluminum, zinc and their alloys is presented. The work program and current status of the US national organizations contributing to and developing test methods and process standards are summarized along with those of ISOATC 107/SC 5. The Secretariat of the ISO/TC 107/SC 5, Thermal Spraying was transferred from AFNOR, France, to ANSI, US, in June 1995. ANSI, in turn, designated AWS to be its delegate in thermal spray matters. The work program of the newly formed SSPC/NACE/AWS Tri-Society Committee on thermal spray coatings for the corrosion protection of steel is summarized.
