ASTM F1135

This specification covers the basic performance requirements and associated test methods for eight grades of electrolytic or mechanical coatings of cadmium or zinc that have been followed by a chromate and baked organic coating for ferrous and nonferrous fasteners. The coatings shall be tested, and conform accordingly to requirements for thickness, corrosion resistance, and adhesion.
