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. An asm in plating thickness results in a larger peak from the plating material and a smaller peak from the base material. 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 b56 energy at a different wavelength so the plating and base material show separate peaks in the XRF spectrum.


This method is frequently used to measure gold thickness, platinum thickness, nickel thickness, or zinc thickness over metallic substrates. A minimum area of 0.

Material testing you can trust since 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 ast, then calculating the intensity of the energy returned by the plating versus the base material.

Measuring coating thickness was one of the first applications of x-ray fluorescence spectrometry and is still one of the most common uses h568 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 B Cannot measure elements with an atomic weight less than that of calcium.

Eastern Applied associates are available to help with safety radiation related questions and training if needed. It also provides an overview of calibration astn and best practices along with standard-less fundamental parameters calibrations.

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. Eastern Applied Research, Inc. Standards of known thickness are required to generate asmt calibration curve for each plating and base material combination.


Results are reported in a table with five or more readings per sample. In all, thirteen satm factors are highlighted and worth knowing about in case issues occur. However, the ASTM B standard also details some variables that an operator may not think of; such as sample curvature, substrate composition, and surface cleanliness.
