Dustiness tape also known as dust evaluation tape or dust evaluation kit is recommended tape and magnifier to be used for assessing the amount of dust on blasted steel surfaces or dust rating, which have been prepared for painting. It is also known as test for assessment of surface cleanliness.
Dustiness tapes provide pictorial ratings for the assessment of the average quantity of dust as well as descriptive classes for the assessment of the average size of the dust particles.
The method is based on pressing a pressure-sensitive adhesive tape on to the steel surface to be tested. Dust evaluation tapes are used to carry as a pass/fail test by comparison with specific limits or by permanently recording the dust present on a surface by mounting the tapes.
