Описание (английский):

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

EN ISO 8502-3:2017 (ISO 8502-3:2017) specifies a simple, qualitative method for the assessment of dust on steel surfaces prepared for painting using a pressure-sensitive tape. The procedure produces pictorial ratings for the average quantity of dust and descriptive classes for the average particle size, enabling use as a pass/fail inspection or to create a permanent record of surface dust contamination prior to coating application.

Key topics and requirements

Method principle: press a pressure-sensitive adhesive tape onto the steel surface, remove it, mount the tape on a contrasting display board and visually assess the deposited dust.
Assessment outputs:
- Pictorial ratings for average dust quantity (qualitative scale).
- Descriptive classes for average dust particle size.
Scope and applicability:
- Intended for dust remaining on cleaned steel substrates prepared for painting.
- The document states the method is useful for steel surfaces corresponding to rust grades A, B or C (per ISO 8501‑1).
Materials and references:
- Uses pressure-sensitive tapes conforming to relevant test methods (see IEC 60454-2).
- Terminology aligned with ISO 4618.
Documentation: test reports should record location, date/time, number of tests, pictorial rating/class and any reference specimens used. Annex A provides guidance on a spring-loaded roller for tape application.

Practical applications

Quality control and inspection on blasting, fabrication and construction sites to check residual dust prior to painting.
Coating acceptance testing for contractors, inspectors and owners (shipbuilding, offshore structures, bridges, pipelines, industrial steelwork).
Comparative evaluations of cleaning methods or environmental contamination by using standard specimens to benchmark results.
Useful where dust can affect coating adhesion or trap moisture and salts that promote corrosion.

Who uses this standard

Coating inspectors and QA/QC teams
Surface preparation engineers and specifiers
Paint manufacturers and applicators
Asset owners and project managers responsible for protective coatings
