Iso 85023 Dust Level Chart Pdf Updated

The current version of the standard is ISO 8502-3:2017 , which replaced previous editions like the 1992 version. This standard provides a qualitative, pressure-sensitive tape method to assess the quantity and size of dust remaining on blast-cleaned steel surfaces before painting. iTeh Standards ISO 8502-3 Dust Level Classifications The assessment is divided into two primary metrics: Quantity Rating Size Class iTeh Standards Particle Size Description Particle Diameter No particles visible under 10x magnification Visible under 10x magnification, not by naked eye Just visible with normal/corrected vision Clearly visible with normal/corrected vision Large particles clearly visible Very large particles clearly visible Quantity Rating (1–5):

Determined by comparing the tape sample to pictorial references that show the density of dust coverage. Common Acceptance Criteria: Many painting specifications require a maximum Quantity Rating 2 Size Class 2 for high-performance coatings. Rösler Group The Critical Role of ISO 8502-3 in Surface Preparation Introduction

Surface preparation is widely regarded as the most critical stage in any industrial coating project. While visible contaminants like rust and mill scale are often the primary focus, microscopic "invisible" threats like residual dust can be equally devastating to a coating's lifespan. ISO 8502-3 provides the standardized framework necessary to detect and quantify these particles using a simple yet effective pressure-sensitive tape method. ISO - International Organization for Standardization The Impact of Dust on Coating Integrity

Residual dust on blast-cleaned steel acts as a "bond-breaker" between the substrate and the protective coating. Even a thin layer of microscopic particles can reduce adhesive strength, leading to premature delamination or blistering. Furthermore, dust is often hygroscopic; it can trap moisture against the steel, accelerating corrosion under the paint film, often before the asset even enters service.

Important Clarification: There is no official document named "ISO 85023." The correct standard is ISO 8502-3. This is part of the ISO 8502 series, which deals with surface cleanliness tests. iso 85023 dust level chart pdf updated

As of the latest revision (ISO 8502-3:2017), the official chart is not freely redistributable due to copyright by ISO. However, you can legally obtain the updated PDF via:

  1. ISO.org: Official store (approx. 120–200 CHF).
  2. National Standards Bodies: ANSI (USA), BSI (UK), DIN (Germany), JSA (Japan).
  3. Coating Inspection Manufacturers: Elcometer, DeFelsko, TQC Sheen often provide summarized reference charts free with their products.

⚠️ Warning: Always ensure you download the 2017 revision or later. Older pre-2010 versions lacked the refined particle size classification and adhesive transparency specifications.

If you need a free quick-reference PDF for field use, many NACE (now AMPP) and SSPC guides offer condensed versions. Search for: "ISO 8502-3:2017 free reference card" or check your coating manufacturer’s technical data sheet (TDS) appendix. Notes on compliance and liability
