The values given in parentheses are for information only. 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. Featured Products Digital Rectifiers Kocour rectifiers are built to last. Calibration and Standardization 7. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
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. Electroplating Includes agitators, hull cells, timers, anodes and cathodes, rectifiers, plater’s tape, and other plating accessories. 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.
They may be coated aluminum plates, or may be foils or shims of? General Laboratory General Laboratory. Originally approved in Factors Affecting the Measuring Accuracy 8. Buffing and Polishing Includes abrasives, bar compound, buffing wheels, polishing lubricants, specialty compounds, buffing kits.
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? Kocour Company is ranked first in the metal finishing industry, Kocour enjoys astk worldwide reputation for high quality products and services for the Plating Industry.
Summary of Test Asstm 4. 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.
For a given basis metal, the higher the measuring frequency, the smaller the critical thickness of the basis metal. Therefore, measurements made too near an edge or inside corner will not be valid unless the instrument is speci?
ASTM B244 – 09(2014)
To those of you who are already Kocour customers, thank you. Analytical Testing Includes analytical test papers, solutions, b24, indicators, plating test sets, and specialized measurements View All. If there is no difference between the readings, the critical thickness is exceeded.
Thickness Testing Includes coulometric modules and testers, calibration standards, repair services, and replacement parts. Its value should be determined experimentally, if not supplied by the manufacturer of the measuring instrument, since it depends xstm both the measuring frequency of the probe system and the electrical conductivity of the basis metal.
Electroplating Includes agitators, hull cells, timers, anodes and cathodes, rectifiers, plater’s tape, and other plating accessories View All. An adjustment will affect the outcome of subsequent readings. 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.
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. Digital Rectifiers Kocour rectifiers are built to last.
Allow weeks delivery. Standards suitable for many applications of the test method are commercially available and may be used provided the certi? Kocour Company appreciates the opportunity to introduce you to our company. A one-year calibration interval is a typical frequency suggested by many instrument manufacturers. Hull Cells The Kocour Hull Cell is unmatched for its sturdy construction, durability and ease of use.
If not, either use the back-up method in 7.
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. When possible, back up the basis metal of the standard asfm of the test specimen with a sufficient thickness of similar material to make the readings independent of the basis metal thickness.
