Chicago, IL Phone: Analytical Testing Includes analytical test papers, solutions, reagents, indicators, plating test sets, and specialized measurements View All. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

For a given basis metal, the higher the measuring frequency, the smaller the critical thickness of the basis metal. The characteristics of this secondary? This eddy-current method is nondestructive and is suitable for measuring the thickness of anodic coatings on aluminum, as well as the thickness of most nonconductive coatings on nonmagnetic basis metals.

With name recognition that is ranked first in the metal finishing industry, Kocour enjoys a worldwide reputation for high quality products and services. Precision and Bias Because of this, and despite the use of special probes or? Made of 16 and 18 gauge CRS and powdercoated, our rectifiers are the “tanks” of the industry.

Electroplating Includes agitators, hull cells, timers, anodes and cathodes, rectifiers, plater’s tape, and other plating accessories. Local variations in coating thickness may also require that a number of measurements be made in any given area; this applies particularly to a rough surface see 8.

A probe is placed directly on the coated surface in a perpendicular position and electronic circuitry is used to convert a reference signal into a coating thickness measurement.

Hull Cells The Kocour Hull Cell is unmatched for its sturdy construction, durability sstm ease of use. Foils are subject to indentation and should, therefore, be replaced frequently. When possible, back up atsm basis metal of the standard or of the test specimen with a sufficient thickness of similar material to make the readings independent of the basis metal thickness.

If there is no difference between the readings, the critical thickness is exceeded. A number in parentheses indicates the year of last reapproval.

A way to determine if the basis metal thickness exceeds the critical thickness is to make measurements before and after backing up the basis metal with similar metal at least 3 mm mils thick.

An adjustment will affect the outcome of subsequent readings. Thickness Testing Includes coulometric modules and testers, calibration standards, repair services, and replacement parts.

Attention shall be given to the factors listed in Section 8 and to the procedures described in Section 9.
