This document specifies a method for the determination of the particle size distribution of coating powders by sieve analysis. Particle size distributions with a maximum of less than 100 µm is determined by laser diffraction, ISO 8130‑13. This method is used especially for determining the oversize material or for the presence of contamination and can be used as a quality control procedure ("go"/"no go" test) by checking the amount retained on a single sieve. The following particle sizes are typical for coating powders, however the particle size can deviate depending on the application: — thin-film technology: 1 µm to 63 µm; — electrostatic coating: 10 µm to 200 µm; — fluidizing-bed method: 100 µm and above. NOTE Sieves with a mesh size smaller than 32 µm are not practical and are likely to become blind during use.
Abstract
Overview
ISO 8130-1:2019 - Coating powders: Determination of particle size distribution by sieving specifies a standardized sieve-analysis method to determine particle size distribution of coating powders. The method is primarily used to detect oversize material or contamination and to perform simple quality‑control (“go”/“no‑go”) checks by measuring mass retained on a sieve. For powders with maximum particle sizes below 100 µm, laser‑diffraction (ISO 8130‑13) is recommended instead.
Key topics and technical requirements
- Scope & purpose
- Sieve analysis for coating powders to identify oversize particles/contamination and support QC decisions.
- Typical particle size ranges (application-dependent): thin‑film 1–63 µm; electrostatic 10–200 µm; fluidized‑bed ≥100 µm.
- Note: sieves <32 µm are impractical (likely to blind).
- Apparatus
- Procedure essentials
- Representative sampling per ISO 15528.
- Determinations carried out in duplicate using fresh powder for each run.
- Typical test portion: 10 g (to be agreed between parties).
- For air‑jet sieving: standard operation ~300 ±15 s (shorter 180 ±15 s permitted if complete by observation); controlled pressure and nozzle rotation; avoid sieve blinding.
- Manual and vibratory sieving options described with guidance to avoid particle attrition and mesh blocking.
- Sieve selectivity factors
- Apparatus/method (sieve type, mesh geometry, movement, sieving aid), test material properties (particle shape, agglomeration, humidity, static), and test settings (duration, air flow, vibration).
Applications and who uses it
- Primary users
- Powder coating manufacturers, paint and varnish producers, QC laboratories, material suppliers, test labs and equipment manufacturers.
- Practical uses
- Quality control (go/no‑go checks), production monitoring, incoming inspection for contamination/oversize particles, R&D when evaluating powder processing or sieving performance.
