AAMA Offers Updated Coatings Specs
The American Architectural Manufacturers Association has announced the publication of AAMA 907 “Voluntary Specification for Corrosion Resistant Coatings on Carbon Steel Components Used in Windows, Doors and Skylights.”
The specification describes requirements for corrosion resistant coatings on carbon steels used for hardware components in window, door and skylight applications.
The specification is updated from the 2012 version and includes a new test report section along with a clarified scope, according to Jeff Dorsch (AmesburyTruth), chair of the AAMA 907 Task Group.
“The AAMA 907 standard for acceptable coatings for mild steel components and assemblies was re-worked to become more performance based and less prescriptive,” said Dorsch.
“In addition, specific references to cadmium plating were removed due to the material’s inclusion on many of the green industry’s red lists. A manufacturer can utilize any number of plating or material options as long as the results after neutral salt spray testing are in accordance with the 907-15 standard.”
Moreover, the requirements in the standard are functional and not intended to address aesthetics. Due to the diversity of corrosive environments that windows and doors are exposed to, this specification does not imply a specific service life, according to the AAMA. Fasteners are also not included in the scope of the specification.
AAMA 907-15 is available for download by AAMA members at a cost of $15. Non-members may purchase the document for $45.
