Overview - EN ISO 8130-1:2019 (Coating powders, sieve analysis)

EN ISO 8130-1:2019 specifies a standardized method to determine the particle size distribution of coating powders by sieving. The method is intended primarily to detect oversize material or contamination and can be used as a simple quality control (“go”/“no go”) check by measuring the mass retained on a single sieve. For powders with a maximum particle size below 100 µm, laser diffraction (ISO 8130‑13) is the preferred method.

Key topics and technical requirements

• Scope and purpose: Sieve analysis for coating powders to identify oversize particles, contamination and for QC.
• Typical particle size ranges:
  • Thin-film technology: 1 µm to 63 µm
  • Electrostatic coating: 10 µm to 200 µm
  • Fluidizing‑bed method: 100 µm and above
• Limits: Sieves with mesh sizes smaller than 32 µm are not practical and tend to blind.
• Principle: A weighed sample is separated into fractions by sieves; the mass of material retained on each sieve is determined.
• Sieving methods:
  • Manual sieving (gravity / hand)
  • Machine sieving with air‑jet sieve apparatus (prevents blinding by a rotating jet)
  • Vibratory sieve machines (single or stacked sieves)
• Apparatus and accessories: circular metal test sieves (200 mm or 300 mm dia.), balance (0.01 g), mallet, magnifying glass (≥×5), ultrasonic cleaning bath, soft brush.
• Sampling and procedure: Sampling per ISO 15528; choice of sieve mesh sizes per ISO 565/ISO 3310; procedures cover sample prep, sieving selection, number of determinations, result expression, precision and test reporting.

Practical applications and users

• Who uses this standard:
  • Paint, varnish and powder coating manufacturers
  • Quality control and testing laboratories
  • Raw materials suppliers and R&D teams developing powder coatings
  • Procurement/specification engineers and regulatory bodies
• Typical uses:
  • Routine QC to pass/fail batches by amount retained on one sieve
  • Investigation of contamination or oversized particles
  • Characterization of powder batches for process selection (electrostatic, fluidized bed, thin-film)
  • Comparing production lots and supplier qualification
