ASTM B568 (measurement of coating thickness by XRF)
This method is frequently used to measure gold thickness, platinum thickness, nickel thickness, or zinc thickness over metallic substrates. Standards of known thickness are required to generate a calibration curve for each plating and base material combination. Our laboratory also provides laboratory services for plastic testingmetal testingrubber testingoil testingpaint testingplating testingadhesive testingcircuit board asttmand other testing.
In all, thirteen 13 factors are highlighted and worth knowing about in case issues occur. Results are reported in a table with five or more readings per sample.
Material testing you can trust since Measuring coating thickness was one of the first applications of x-ray fluorescence spectrometry and is still one of the most common uses of the technology. Eastern Applied Research, Inc. A minimum area of 0.
It also provides an overview of calibration techniques and best practices along with standard-less fundamental parameters calibrations. An increase in plating thickness awtm in a larger peak from the plating material and a smaller peak from the base material.
This industry standard ASTM B should be reviewed by all operators of x-ray fluorescence because it offers a beneficial overview and highlights proper implementation of the technology.
ASTM B (measurement of coating thickness by XRF) | Eastern Applied Research, Inc.
Advanced Plastic and Material Testing, Inc. ASTM B X-Ray Fluorescence XRF is a non-destructive method of measuring plating thickness by using an X-ray beam to excite the surface of a sample and then calculating the intensity of the energy returned by the plating versus the base material.
Cannot measure elements with an atomic weight less than that of calcium. The benefit to operators is that it details the variations in x-ray spectrometry systems and explains how XRF works with some terminology that may be useful.
Eastern Applied associates are available to help with safety radiation related questions and training if needed.
It is important to note that ASTM B does not detail safety procedures relating to operation of x-ray spectrometry and refers the reader to the appropriate governing bodies and regulations.
Each element emits energy at a different wavelength so the plating and base material show separate peaks in the XRF spectrum. However, the ASTM B56 standard also details some axtm that an operator may not think of; such as sample curvature, substrate composition, and surface cleanliness.
So, the majority of analyzer certifications that Eastern Applied Research technicians provide are for coating thickness applications and those certifications actually reference the ASTM Standard B
