Class 2 (Moderate – For Industrial Environments C3/C4)

• Quantity: Visible dust particles covering 1% to 5% of tape area.
• Particle Size: Some particles between 50–100 µm.
• Acceptance: Acceptable for standard systems (e.g., alkyds, epoxies).

1. What the standard actually is

• ISO 8502-3:2017 (current version) – Preparation of steel substrates before application of paints and related products – Tests for the assessment of surface cleanliness – Part 3: Assessment of dust on steel surfaces prepared for painting (pressure-sensitive tape method)
• There is no ISO standard numbered “85023” – the correct reference is ISO 8502-3.

Class 1 (Excellent – Typically Required for C5-M / Offshore)

• Quantity: No visible dust on tape without magnification. Under 4–10× magnification, isolated particles (<1% coverage).
• Particle Size: Only particles <50 µm visible.
• Acceptance: Yes for high-durability coatings.

Sampling plan & frequency

• Guidance table by surface area (e.g., <10 m² → 3 samples; 10–100 m² → 5–10 samples; >100 m² → 10+).
• When to sample: immediately before coating application, after overnight exposure, after weather events.
