Our cast iron weights undergo a special phosphatizing process in which the metal is thoroughly cleaned and mildly etched to allow exceptional finish adhesion. The weights are then coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards. This two-step process ensures a long-lasting finish that greatly reduces the possibility of corrosion.

Classes Available:

ASTM Class 7

Applications:

Field standards for testing industrial devices Class III, Class IIlL or IIII
Testing for non-marked scales without Class designation
