Marta minimized the PDF and opened her field notes. She remembered that turbine. The steel had looked clean, but there had been a faint, shadowy haze in one corner. Under the old rules, it was a Size 2.5—acceptable. Under the new updated chart, with its stricter clustering definition, it was a clear Size 3. Reject.

For field inspectors, quality control managers, and blasting contractors, having a high-resolution, updated reference chart is essential for accurate assessments.

The procedure for using the chart is standardized to ensure reliable results:

Instead, professional inspectors utilize verified field kits from established coating instrument manufacturers. Dust Test After Blast Cleaning IOGS Official Video iso 85023 dust level chart pdf updated

The standard uses a scale from to denote the density of particles:

The table below provides a clear breakdown of the dust particle size classes as defined by the standard.

“Better than a coating failure five years from now,” Marta replied. “The chart doesn’t lie, Jan. It’s been updated for a reason. Someone, somewhere, had a delamination because of old Size 3 dust. We’re not going to be that someone.”

Advanced inspection kits now utilize digital optical scanners. The inspector takes the tape sample, places it into a portable scanning device, and the software automatically calculates the percentage of dust coverage, matching it perfectly to the ISO 8502-3 rating scale.

The ISO 8502-3 method is a qualitative pressure-sensitive tape test used to measure the amount and size of dust particles remaining on a cleaned surface, typically before coating application. It is particularly crucial for steel surfaces that have been abrasive blast-cleaned. Key Components of the Standard

. Dust particles left on a steel substrate act as a barrier, preventing proper coating adhesion and trapping moisture that leads to catastrophic, premature coating failures like blistering, peeling, and under-film corrosion.

Low density; small, distinct groups of particles are visible.
