Differences in Surface Profile Measurements: ASTM D4417- Method B vs. Method C

What is Surface Profile and Why is it Necessary? Surface profile is defined as a measurement of the maximum peak-to-valley depth created by abrasive impingement against a surface during abrasive blast cleaning operations, or by an impact-type power tool. During abrasive blast cleaning, the mass of the abrasive and the velocity of the abrasive movement created by compressed air generates kinetic energy (the abrasive can reach speeds of over 600 miles per hour as it exits the blast nozzle). When...

What is a Base Metal Reading and How Does It Effect Coating Thickness Measurements?

For many in the health care/fitness industry, BMR is an acronym for basal metabolic rate. Sorry to disappoint if you thought this would be a health science article about expending energy. Rather, this article is about a different BMR: Base Metal Reading. We’ll describe what it is, its significance, how to obtain it, and how it impacts coating thickness. Introduction to Coating Thickness Standards There are two common industry standards that govern measurement of coating dry film thickness on metal substrates,...
