Special Standards



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.
  • B244 Measurement of thickness of anodic coatings on aluminum and of other non-conductive coatings on non-magnetic basis metals with Eddy-Current Instruments.(ISO 2360)
  • B499 Measurement of coating thicknesses by the magnetic method: Non-magnetic coatings on magnetic basis metals. (ISO 2178)
  • B504 Measurement of thickness of metallic coatings by the Coulometric method. (ISO 2177)
  • B530 Measurement of coating thicknesses by the magnetic method: Electro-deposited nickel coatings on magnetic and non-magnetic substrates. (ISO 2361)
  • B567 Measurement of coating thicknesses by the Beta-Backscatter method. (ISO 3453)
  • B568 Measurement of coating thicknesses by X-Ray Spectrometry. (ISO 3497)

Product Features:

  • ALL KOCOUR THICKNESS STANDARDS ARE TRACEABLE TO THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY.
  • STANDARDS TRACEABLE TO NIST - Standards are traceable to N.I.S.T. by the weight per unit area method.
  • CONFORMANCE TO ASTM AND ISO STANDARDS - Standards are produced to conform to applicable ASTM and ISO standards, controlled to ± 10% of the certified thickness.
  • MULTIPLE COATINGS STANDARDS - Kocour Company can provide a wide variety of multiple coating Standards to enable calibration on a single spot.
  • ALLOY STANDARDS - VERIFICATION OF ALLOY - Standards with alloy or co-deposition can be provided with verification of alloy or minor metal co-deposition content within ± 2% desired content.
