A modern, fast method of measuring surface profiles on blasted surfaces!
Thickness Gauge With Special Modified Anvil
With the digital version,
an inspector can record
time, date, measurement
sequence number
and profile height with
the push of a button.
At the end of a work
day, the measurements
can be uploaded to a
spreadsheet on the inspector’s
laptop or office
computer.
Testex replica tape can be used with a gauge to measure the surface
roughness (“profile”) of blast-cleaned steel in the roughness range
0.8 to 4.5 mils (or 20 to 115 micrometers). Because inspectors,
as a rule, have a target profile in mind, it is always best to start
measurements with the grade of tape that has the target profile closest
to the center of its range. Each grade of replica tape is most
accurate near the center of its specified range.
Dial Gauge with Anvil
Digital Gauge with Anvil
Always confirm measurements near the ends of a given grade’s range using the next higher or lower
grade of tape.
Technical Data
Grade
Range When Used With Gauge
Medium:
5 to 75 microinch / 0.1 to 2 microns
Coarse Minus:
0.5 to 1.0 mils / 12 to 25 microns
Coarse:
0.8 to 2.5 mils / 20 to 50 microns
X-Coarse:
1.5 to 4.5 mils / 40 to 115 microns
X-Coarse Plus:
4.6 to 5.8 mils / 116 to 147 microns
Instructions for using Press-O-Film® on Blasted Surfaces
Locate a representative surface site.
Select grade of Press-O-Film® – 0.8 to 2.5 mils use “Coarse”, 1.5 to 4.5 mils use “X-Coarse”.
Prepare snap gauge, clean anvils, adjust dial gauge to read a minus 2 mils (8 mils when anvils are shut.)
Peel Press-O-Film® from slide.
Check unexposed film with gauge. Film may vary in thickness and maximum limits of profiles cannot exceed thickness of film coating.
Apply film on blasted surface.
Rub burnishing tool over the round cut-out portion of Press-O-Film®. Press-O-Film® will become darker when replicated, so make sure that the entire circular area has uniformly darkened.
Remove replica and place between anvils on snap gauge, making sure replica is centered in between anvils. Gauge reading is the average maximum peak to valley heights of the blasted surface. (When snap gauge is adjusted as per Step 3).
