: A scale of 0 to 5 based on measured particle diameters. The ISO 8502-3 Dust Level Chart Breakdown

These charts are updated by manufacturers to ensure perfect print quality, accurate color contrast, and durability for use in harsh industrial environments. The chart is an essential tool that allows an inspector to visually compare the dust particles collected on tape with standardized pictorial references.

The ISO 85023 dust level chart is a visual and descriptive reference table that classifies the amount of dust remaining on a blasted steel surface. It works in conjunction with the (also known as the "tape test").

A specialized adhesive tape is applied to the surface, pressed down, and then removed to collect dust particles. iso 85023 dust level chart pdf updated

Many coating specifications mandate a Class 2 or lower rating, making this test critical for inspection reports.

Below is a that includes the updated dust level chart, interpretation guide, and practical application. You can copy this directly.

What is the specified for your project? What type of coating/primer are you applying? What abrasive media was used for blasting?

The specification for the coating project will typically state the maximum permissible dust quantity grade and size rating. For example, a project specification may state, "Maximum dust quantity: Grade 2 per ISO 8502-3." The ISO 85023 dust level chart is a

The primary version in active use globally is , which was reviewed and reconfirmed as the current version. This standard is widely deployed across marine, oil and gas, infrastructure, and structural steel manufacturing fields where defensive industrial coatings are mandatory. The Core Classifications: Quantity and Size

Moderate accumulation of dust particles. Clearly populated surface.

While quantity impacts adhesion, particle size determines the "smoothness" and integrity of the first coating layer. INTERNATIONAL STANDARD ISO 8502-3
