If you feel that your comments have bb244 received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Electroplating Includes agitators, hull cells, timers, anodes and cathodes, rectifiers, plater’s tape, and other plating accessories View All.
Attention shall be given to the factors listed in Section 8 and to the procedures described in Section 9. Kocour Company is ranked first in the metal finishing industry, Kocour enjoys a worldwide reputation for high quality products and services for the Plating Industry. Analytical Testing Includes analytical test papers, solutions, reagents, indicators, plating test sets, and specialized measurements View All. If not, either use the back-up method in 7.
Website by Distant Horizon. 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.
Proven Structure M1 – Structure
If there is no difference between the readings, the critical thickness is exceeded. Digital Rectifiers Kocour rectifiers are built to last.
Are you sure you to want to delete this row? Made of 16 and 18 gauge CRS and powdercoated, our rectifiers are the “tanks” of the industry. The values given in parentheses are for information only. A number in parentheses indicates the year of last reapproval. If the basis metal is rough it may also be necessary to check, and adjust if necessary, the zero of the instrument at several positions on a sample of the uncoated rough substrate.
Hull Cells The Kocour Hull Cell is unmatched for its sturdy construction, durability and ease of use. Foils are subject to indentation and should, therefore, be replaced frequently. The eddy currents in turn create a secondary magnetic? 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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Kocour Company appreciates the opportunity to introduce you to our company.

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? To those of you who are already Kocour customers, thank you. This standard has been approved for use by agencies of the Department of Defense. Both the test surface and instrument probe should be kept free of foreign material.
With name recognition that is ranked first in the metal finishing industry, Kocour enjoys a worldwide reputation for high quality products and services. Therefore, measurements satm too near an edge or inside corner will not be valid unless the instrument is speci?
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.
Resilient foils should be avoided if b24.
ASTM International takes no position respecting the validity of any patent rights asserted in b24 with any item mentioned in this standard. A one-year calibration interval is a typical frequency suggested asttm many instrument manufacturers. Thickness Testing Includes coulometric modules and testers, calibration standards, repair services, and replacement parts.
Minimum order 15 pcs. Because of this, and despite the use of special probes or? They are advantageous for adjustments on curved surfaces, and are more readily available than coated standards. Summary of Test Method 4. Factors Affecting the Measuring Accuracy 8.
