A complete dust assessment evaluation yields two metrics: (how much dust is present) and Dust Particle Size Class (how large the particles are). 1. Dust Quantity Ratings (0 to 5)

: Particles clearly visible with normal vision, ranging from in diameter [1.19]. Class 4 : Particles ranging between in diameter [1.19]. Class 5 : Large debris particles greater than in diameter [1.19]. Step-by-Step ISO 8502-3 Test Procedure

To accurately classify the size of the dust, inspectors use a illuminated magnifier with a graduated scale (graticule). Size Class Particle Description / Dimension Inspection Visibility Particles less than in diameter Particles only visible under magnification. Not visible to the naked eye. Class 1 Particles between Particles just visible with normal or corrected vision. Class 2 Particles between Particles clearly visible with normal or corrected vision. Class 3 Particles between iso 85023 dust level chart pdf updated

Trace amounts; particles visible only under magnification. Rating 2: Dust barely visible to the naked eye. Rating 3: Particles clearly visible. Rating 4: Significant dust accumulation; easily noticeable. Rating 5: Heavy contamination. 2. Dust Size Classes (0–5)

Always perform a high-pressure air blow-down after blasting. Ensure the compressed air used for blowing down is strictly oil-free and dry (compliant with ASTM D4285).

ISO 8502-3 describes a method for assessing the quantity and size of dust particles on blast-cleaned steel surfaces. The procedure uses a specific type of pressure-sensitive adhesive tape to lift dust from the surface. This tape is then applied to a white or black display board to be evaluated visually against a comparator chart. The ISO 8502-3 Dust Level Chart (Pictorial Rating) To future-proof your coating inspections, do this today:

The updated ISO 8502-3 PDF offers several benefits to industries that rely on coating applications, including:

Evaluating a surface using the tape method yields two specific data points: and Dust Particle Size Class . 1. Dust Quantity Ratings (1 to 5)

The new chart emphasizes that even if quantity is Class 2, if any particle exceeds 100 µm, the overall rating drops to Class 3. Class 4 : Particles ranging between in diameter [1
