Testex Tape
Article No. 14425
Testex X-Coarse Tape 1.5 - 4.5 Mils
Features
- The Testex replica tape can be used with the 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).
- Each roll of tape is labeled with a manufacturing code and date for tracking purposes.
- The tape does not expire and will last for years if kept in a relatively clean, dry environment.
- Temperatures above 120°F (50°C) will degrade the sticky tapes that hold the Press-O-Film. Temperatures above 140°F (60°C) will degrade the actual Press-O-Film.
- Petroleum products will degrade the Press-O-Film and should be kept away from the tape.
- Each roll is 50 impressions.
- 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.
- Always confirm measurements near the ends of a given grade’s range using the next higher or lower grade of tape.
- Press-O-Film Tape is also used with the Positector RTR - Replica Tape Reader
