3D Analysis of the Bristle-Blasted Surface Profile
A 2015 3D optical analysis characterized the surface texture and anchor profile produced by bristle blasting, giving inspectors measured data behind the 65-85 micron Rz figure.
"65–85 µm Rz" is a number; what the surface actually looks like in three dimensions is the evidence. This page summarizes the 2015 3D optical analysis of bristle-blasted surface texture.

What does it cover?
Using 3D optical measurement, the study characterizes the texture bristle blasting produces: the crater-like impressions left by rebounding bristle tips, their distribution, and the resulting profile parameters — the same class of surface data inspectors use replica tape and profilometers to verify in the field.
Why does it matter?
Coating specifications name profile ranges, and inspectors have to verify them. Measured 3D data on what the tool produces gives inspectors reference data to verify against. For field measurement practice, see the anchor profile field guide and M-TESTCO instruments.
