ASTM B568 (measurement of coating thickness by XRF)

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. 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 B568. This standard is titled Standard Test Method for Measurement of Coating Thickness with X-Ray Spectrometry, and operators of ED-XRF systems (especially those new to the technology) may find it beneficial to take a few moments to read the standard.
