While the full official standard must be purchased directly from the International Organization for Standardization (ISO) , summary charts and data sheets are often provided by equipment manufacturers:
Match the dust density against the updated pictorial reference chart. Inspect the particle dimensions using the 10x illuminated magnifier. Why Downloading an Updated PDF Matters Dust Tape Test - Elcometer USA
Dust particles are not visible under 10x magnification. iso 85023 dust level chart pdf updated
This rating defines the concentration or density of the dust particles captured on the tape.

All official documentation, charts, and kits will use the correct designation ISO 8502-3:2017 . While the full official standard must be purchased
Surface preparation is the most critical factor in determining the lifespan of a protective coating system. Among various surface contaminants, dust particles deposited on blast-cleaned steel surfaces can severely degrade coating adhesion, leading to premature blistering, peeling, and failure.
Very low dust level; particles are barely visible to the naked eye. This rating defines the concentration or density of
Particles just visible with normal vision (50 µm to 100 µm). Class 3: Clearly visible particles (100 µm to 500 µm). Class 4: Large particles (0.5 mm to 2.5 mm). Class 5: Very large particles (greater than 2.5 mm). Why You Need an Updated PDF Chart
