Minimum order 15 pcs. The characteristics of this secondary? Digital Rectifiers Kocour rectifiers are built to last. To those of you who are already Kocour customers, thank you. They are advantageous for adjustments on curved surfaces, b424 are more readily available than coated standards.
Allow weeks delivery.
If the roughness of the substrate surface is small, astj to the coating thickness, its effect will probably be negligible. NF6M Stand Versatile and simple with connecting cable and air agitation system. Thickness Testing Includes coulometric modules and testers, calibration standards, repair services, and replacement parts View All.

There is no standard time interval for re-calibration, nor is one absolutely required, but a calibration interval can be established based on experience and the work asm. 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.
Material Safety Data Sheets. Made of 16 and 18 gauge CRS and powdercoated, our rectifiers are the “tanks” of the industry. NOTE 1—Although, theoretically, this test h244 can be used for measuring nonconductive coatings on a magnetic basis metal, its use for coatings below 25?
Chemical conversion coatings are too thin to be measured by this test method. Both the test surface and instrument probe should be kept free of foreign material. 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. Resilient foils should be avoided if possible.
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. 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.
Originally approved in This standard has been approved for use by agencies of the Department of Defense. Last previous edition approved in as B — 97 atm Factors Affecting the Measuring Accuracy 8. General Laboratory General Laboratory. Summary of Test Method 4. An adjustment will affect the outcome of subsequent readings. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

If not, either use the back-up method in 7. With name recognition that is ranked first in the metal finishing industry, Kocour xstm a worldwide reputation for high quality products and services.
A probe is placed directly on the coated b44 in a perpendicular position and electronic circuitry is used to convert a reference signal into a coating thickness measurement. Therefore, measurements made too near an edge or inside corner will not be valid unless the instrument is speci?
