of the average maximum peak-to-valley
height of the surface roughness profile. The Gage automatically
subtracts the thickness of the polyester film from all measurements.

How to Measure

1. Locate a representative site for
measurement. Clean the surface to be
tested using a cleaning putty or other
suitable method (such as compressed
air or pressure-sensitive tape) to
remove dust, debris, or residual blast
