GB/T 18570.3-2005 — This standard specifies the steel surface before application of paints and dust evaluation method. This method provides the assessment of the average number of levels of the icon, but also provides the average size of the dust particles assessment rating.

Optionally one of the following test methods: a) " pass/fail " test, referring to the prescribed limits, qualification test surface dust quantity and average particle size, b) by attaching a pressure-sensitive adhesive tape, lasting record of the test surface dust, pressure-sensitive adhesive tape with a contrasting color in the appropriate floppy disk, card or paper test.

This method is applicable to steel surfaces after cleaning residual dust assessed before cleaning steel surfaces shall comply with ISO 8501-1 requirements rust grades A, B or C. Because the pressure-sensitive adhesive tape elastic finite, it is impossible to clean up after a deep furrow steel surface pit, so not for the initial rust grades of D steel surfaces.

Despite bringing the thumb pressure sensitive adhesive test operation subjective, but usually this is sufficient to meet the requirements, especially useful in the case of surface dust.

Despite bringing the thumb pressure sensitive adhesive test operation subjective, but usually this is sufficient to meet the requirements, especially useful in the case of surface dust. In case of disputes, except those involving rust grade C or D, but can use a spring-loaded pressure-sensitive adhesive tape roll to the back pressure.
