3 .1 .2 Nonmetallic Coatings The adhesion of the coating shall be such that when examined in accordance with Method B of the latest revision of ASTM D 3359, the coating shall achieve a rating of 38 or better. 3.2 Corrosion Resistance The test shall be conducted in accordance with the latest revision of ASTM B 117 . Parts shall withstand exposure for 300 hours without corrosion exceeding one spot visible to the unaided eye per one square inch of significant surface and without any spot larger than 1116 inch (1 .6mm) in diameter. Corrosion is defined as a breakdown of the base material, loss of adhesion of the coating or blistering of the coating . Significant surfaces are defined as surfaces visible once the component is installed . 4.

This specification covers requirements for corrosion resistant coatings on carbon steels used for hardware components in window and door applications . The requirements are functional and are 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. Due to the lack of specifications and/or standards for coatings not covered in Section 2, the testing requirements for other coatings in Section 3 have been made more stringent to address the increased potential for variability in application . NOTE: Some hardware components must meet other AAMA specifications that also specify corrosion resistance requirements. (Example: Sash r- -lances must meet AAMA 902). In those cases, ,. corrosion resistant requirements of the other specification take precedence over those given in this specification. 2. ACCEPTED COATING SPECIFICATIONS The following coatings are accepted if they comply with the indicated specification :
