1.0 SCOPE

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 balances must

meet AAMA 902). In those cases, the corrosion resistant requirements of the

other specification take precedence over those given in this specification.

2.0 ACCEPTED COATING SPECIFICATIONS

The following coatings are acceptable if they comply with the indicated

specification:

Coating or Coating Material Specification

Cadmium Plated ASTM B 766 Class 8, Type II or Type III

Zinc Plated ASTM B 633, Type II

Nickel & Chrome Plated ASTM B 456, Type SC

3.0 OTHER COATINGS

Other coatings may also be used provided they meet the following requirements

for adhesion and corrosion resistance.

3.1 ADHESION

3.1.1 Metallic Coatings

The adhesion of the coating shall be such that when examined in accordance

with any appropriate method described in ASTM B 571, the coating shall not

show separation from the steel component at the interface.

3.1.2 Nonmetallic Coatings

The adhesion of the coating shall be such that when examined in accordance

with Method B of ASTM D 3359, the coating shall achieve a rating of 3B or

better.

3.2 CORROSION RESISTANCE

The test shall be conducted in accordance with 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 1.6 mm (1/16 in) 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 openly visible and

exposed once the component is installed (i.e. rotary operator components when

in open or closed positions, bottom face and exposed portions of wheels of

sliding door rollers, and all areas excluding mounting faces for friction hinges).

3.3 TEST SAMPLES

Manufacturers shall use standard

carbon steel Q panels with a

minimum of 4 square inches or

actual components for the testing.
