Made of 16 and 18 gauge CRS and powdercoated, our rectifiers are the “tanks” of the industry. Originally approved in They are advantageous for adjustments on curved surfaces, and are more readily available than coated standards. Buffing and Polishing Includes abrasives, bar compound, buffing wheels, polishing lubricants, specialty compounds, buffing kits. Resilient foils should be avoided if possible. Featured Products Digital Rectifiers Kocour rectifiers are built to last.
The effects of properties of the substrate composition, shape, roughness, edge effects, electrical properties and coating composition, mass, surface roughnessas well as ambient and surface temperatures, may require adjustments to be made to the instrument. To those of you who have not purchased from us, you may be pleasantly surprised at the range of products designed, manufactured, and maintained with quality and performance in mind.
Chemical conversion coatings are too thin to be measured by this test method. Chicago, IL Phone: NOTE 1—Although, theoretically, this test method can be used for measuring nonconductive coatings on a magnetic basis metal, its use for coatings below 25?
Foils are subject to indentation and should, therefore, be replaced frequently. Its value should be determined experimentally, if not supplied by the manufacturer of the measuring instrument, since it depends on both the measuring frequency of the probe system and the electrical conductivity of the basis metal. Thickness Testing Includes coulometric modules and testers, calibration standards, repair services, and replacement parts. 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.
If there is no difference between the readings, the critical thickness is exceeded. Precision and Bias 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.

To those of you who are already Kocour customers, thank you. Are you sure you to want to delete this row?
There is no standard time interval for re-calibration, nor is one absolutely v244, but a calibration interval can be established based on experience and the work environment. Therefore, measurements made too near an edge or inside corner will not be valid unless the instrument is speci?
Allow weeks delivery. 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.
Analytical Testing Includes analytical test papers, solutions, reagents, indicators, plating test sets, and specialized measurements. Last previous edition approved in as B — 97 It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
If not, either use the back-up method in 7. They may be coated aluminum plates, or may be foils or shims of?
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. Electroplating Includes agitators, hull cells, timers, anodes and cathodes, rectifiers, plater’s tape, and other plating accessories.
For a given basis metal, the higher the measuring frequency, the smaller the critical thickness of the basis metal.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. When possible, back up the 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.
