Description (English):

ISO 8502-3:2017 describes a method for the assessment of dust remaining on cleaned steel surfaces prepared for painting. It provides pictorial ratings for the assessment of the average quantity of dust. It also provides descriptive classes for the assessment of the average size of the dust particles. The method described is a qualitative test useful for a steel surface, before cleaning, corresponding to rust grade A, B or C as defined in ISO 8501‑1. It can be used as a "pass/fail" test or to provide a permanent record of the dust present on a surface.

Abstract

Overview

ISO 8502-3:2017 - Preparation of steel substrates before application of paints and related products - Part 3 - describes a qualitative, pressure-sensitive tape method for assessing dust on steel surfaces prepared for painting. The standard provides pictorial quantity ratings and descriptive dust size classes to evaluate the average quantity and particle size of dust remaining after cleaning. The method can be used as a pass/fail inspection or to create a permanent record of surface dust prior to coating.

Key topics and technical requirements

Principle: Press a piece of pressure-sensitive adhesive tape onto the steel surface, remove it, mount on a contrasting display board and visually assess dust coverage and particle size.
Apparatus & materials
- Adhesive tape: transparent, 25 mm width, peel strength ≥ 190 N/m (IEC 60454-2 test).
- Display board: contrasting colour (e.g., black or white glazed tile, card or paper).
- Spring-loaded roller: calibrated to apply ~39.2 N or 49.0 N (Annex A) or manual thumb application.
- Hand lens: ×10 magnification.
Procedure highlights
- Discard first three turns of tape; use ≈200 mm tape length and press ≈150 mm onto surface.
- Apply pressure by thumb or calibrated roller, moving three strokes each direction, each stroke taking 5–6 s.
- Compare tape to pictorial references to assign a quantity rating (1–5); use Table 1 to assign a size class (0–5) (class 1:
