Testex Micrometer Dial Thickness Gauge
To be used with Testex replica Press-O-Film Tape to measure the surface roughness of blast cleaned surfaces.

The Testex Micrometer Dial Thickness Gauge is to be used with Testex replica Press-O-Film Tape to measure the surface roughness of blast cleaned surfaces.

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.

Standards Governing Use of Replica Tape to Measure Profile

ASTM - (American Society for Testing and Materials) D 4417:

  • Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel

NACE - International (National Association of Corrosion Engineers) RP0287:

  • Standard Recommended Practice: Field Measurement of Surface Profile of Abrasive Blast Cleaned Steel Surfaces Using a Replica Tape

SSPC - the Society for Protective Coatings

ISO - International Organization for Standardization: Standard ISO8503-5 Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates - Part 5: Replica tape method for the determination of the profile

In cases where standards compliance is required, the full original current standard should be consulted.

Instructions
line

  1. Locate a representative surface site.
  2. Select grade of Press-O-Film® – 0.8 to 2.5 mils use “Coarse”, 1.5 to 4.5 mils use “X-Coarse”.
  3. Prepare snap gage, clean anvils, adjust dial gauge to read a minus 2 mils (8 mils when anvils are shut.)
  4. Peel Press-O-Film® from slide.
  5. Check unexposed film with gage. Film may vary in thickness and maximum limits of profiles cannot exceed thickness of film coating.
  6. Apply film on blasted surface.
  7. 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.
  8. Remove replica and place between anvils on snap gage, making sure replica is centered in between anvils. Gage reading is the average maximum peak to valley heights of the blasted surface. (When snap gage is adjusted as per Step 3).

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
