Testex Kit

Measurement of surface profile of blasted steel is necessary to ensure adequate blast profile for coatings adhesion. The Testex Kit contains everything required for testing surface profile, in a plastic case. Testex Replica Tape is compressed against the blasted surface using the included burnishing tool, taking on the impression or replica of the blast profile, which is then measured using the Testex Gauge, which is specifically designed for this application. Testex Tape provides a permanent record of surface profile, making it possible to ensure conformance to specifications for steel preparation prior to coatings application.

The following standards apply to the measurement of surface profile using Testex Tape:

ASTM D 4417:    Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel

NACE RP0287:    Standard Recommended Practice: Field Measurement of Surface Profile of Abrasive Blast Cleaned Steel Surfaces Using a Replica Tape

SSPC - the Society for Protective Coating

ISO 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

Each Testex Kit includes:

  • Testex Tape: 1 roll ea. coarse & extra-coarse Press-O-Film Replica Tape
  • 1 dial thickness gauge
  • 1 burnishing tool
  • 1 training surface
  • complete instructions for use

Contained in a convenient plastic carrying case.
