Grip Handle Weights Class F Cast Iron Painted, Density 7.2 Designed for scale calibration, our solid cast iron test weights are available in the following: NIST Class F 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. All weights are traceable to the National Institute of Standards and Technology (NIST).
