: A scale from 0 to 5 based on physical dimensions measured under magnification. Deciphering the ISO 8502-3 Dust Level Chart
To apply a calibrated force (approx. 39.2 N) to ensure uniform tape adhesion. Step-by-Step Test Procedure
ISO 8502-3:2017 describes a qualitative test method for assessing dust remaining on cleaned steel surfaces prepared for painting. The method is applicable to steel surfaces that, before cleaning, corresponded to rust grades A, B, or C as defined in ISO 8501-1. The standard can be used either as a "pass/fail" test by comparison with specific limits or to provide a permanent record of the dust present on a surface by mounting the used tapes on tiles, cards, or paper.
Press the tape firmly onto the steel surface. Remove Tape: Carefully remove the tape from the surface.
The following outlines the complete procedure for conducting an ISO 8502-3 dust assessment: iso 85023 dust level chart pdf updated
Using an illuminated magnifier, inspectors must measure the average diameter of the trapped dust particles according to six predefined classes: : Particles not visible under magnification [1.19]. Class 1 : Particles visible only under magnification (typically less than in diameter) [1.19].
“This is a disaster,” she whispered. “We have a turbine blade shipment leaving Rotterdam tomorrow. I signed off on it yesterday using the old chart.”

While some sources on the internet mention an "updated chart," the ISO database indicates that the standard was last reviewed and , meaning the 2017 edition remains the current, valid version . There hasn't been a newer revision to the standard itself. What is often referred to as an "updated" version are the commercial dust test comparator charts that manufacturers produce based on this standard. This article will serve as your comprehensive guide to everything you need to know about the ISO 8502-3 dust level chart. : A scale from 0 to 5 based
Heavy dust cover; significant portions of the adhesive tape are masked. Rejected (Requires mandatory solvent/air blow-off)
ISO 8502-3 standard provides a standardized method for assessing the quantity and size of dust on steel surfaces prepared for painting using the pressure-sensitive tape method. ISO - International Organization for Standardization Current Standard Status The most current version of this standard is ISO 8502-3:2017 . While initially published in 2017, it was formally reviewed and confirmed in 2022
For assessing Class 1 and Class 2 particles and Rating 0 surfaces.
To execute a compliant test, standard kits like the or the DeFelsko PosiTest DT are used. Press the tape firmly onto the steel surface
Low density; small, distinct groups of particles are visible.
The evaluation relies on a simple, field-proven technical procedure:
Accessing the correct "iso 85023 dust level chart pdf updated" starts with understanding that the correct standard is . This is the active, definitive method for dust assessment on steel surfaces. The official chart provides a reliable, objective system for rating dust quantity and size, ensuring that surfaces are truly clean and ready for coating. The only way to obtain the official, unaltered PDF is by purchasing it from an authorized distributor. By using the official standard correctly, you can significantly improve coating adhesion and prevent costly premature failures.
