Surface Cleanliness Tape Test

Assessment of Surface Cleanliness

Art. No.: 12704

Cleanliness Test Tape 1" X 72 Yds

The Assessment of Surface Cleanliness is a dust on steel assessment equipment & test for cleanliness. It meets ISO 8502-3. Dust on blast cleaned steel surfaces may reduce the adhesion of applied coatings and by absorbing moisture, it may promote the corrosion of the blast cleaned steel.

  • The Adhesive Tape is a virtually colorless, transparent, self-adhesive, pressure sensitive tape with adhesion strength of at least 190 N/m.
  • The hand lens capable of magnification x 10
  • The Cleanliness Tape Roller helps apply the tape with even pressure

Cleanliness Test Tape 1" X 72 Yds

  1. First discard the first three turns of tape from the roll.
  2. Remove a piece about 8" long.
  3. Touching the adhesive side only at the ends, press about 6" of freshly exposed tape firmly into surface to be tested.
  4. Press by placing the thumb across one end of the tape and moving the thumb along the tape at a constant speed and pressure. Do this three times in each direction making each stroke take approximately 5 to 6 seconds.
    • NOTE: While a test procedure in which pressure is applied to a tape using the thumb is subjective, it is usually adequate, especially for use in situations where surfaces free from dust are required. In disputed cases, except when a rust grade C or D is involved, pressure may be applied to the back of the adhesive tape using a spring-loaded roller. Please refer to ISO F502.
  5. Remove the tape from the test surface.
  6. Display results on an appropriate contrasting background card, tile or paper by rubbing with thumb to adhere.
  7. Determine the QUANTITY OF DUST on the tape by comparing visually an area of the tape equal to an area of reference shown in FIGURE 1 below.
  8. Determine the predominant DUST PARTICLE SIZE on the tape by referencing TABLE 1, which defines six dust particle size classes, designated 0, 1, 2, 3, 4 and 5.
  9. Complete a significant number of tests to properly identify the characteristic of the surface tested. Complete at least three separate tests for each surface of a particular type of aspect. Complete at least two additional tests for each result that has a one or less quantity rating.
    • NOTE: Please refer to the ISO 8502-3 Standard for the exact procedure
