Special Standards, Metallic coatings on metallic substrates, 2.5" diameter hard standards.
Kocour Company has manufactured thickness standards since 1952 to satisfy the need for a reasonably priced consumable standard for its line of coulometric test instruments. Since then, a system has been developed for producing standards with an overall diameter of 2.5" and a usable plated area of at least a 2.125" diameter. The area plated is closely controlled so that the weight per unit area may be determined. This is then converted to thickness with the aid of commonly accepted densities for the plated metal. The distribution of metal throughout the plated area is controlled to ± 10% of the certified thickness.
Kocour Company's continuing commitment to quality is evidenced by its ISO 9001:2015 certification. In recent years, increasingly stringent quality requirements have created the need for the various thickness gauging systems to agree. This usually requires the use of standards manufactured from the same base material and plated from solutions of the same composition as the item to be tested. Kocour Company is filling this need.
The following A.S.T.M. Methods of Test recommend the calibration of thickness testing instruments with the use of thickness standards.
