Paints and varnishes - Determination of pigment content - Part 1: Centrifuge method (ISO 14680-1:2000)

This part of ISO 14680 specifies a test  method for determining the pigment content  of paints in which the solids are sedimented  by centrifugation. It is primarily intended for  checking the composition during the  production of coating materials and as an  acceptance check for the coating material  user. It cannot be applied to coating  materials containing dyestuffs, carbon black  or very finely divided silicon dioxide and very  finely divided titanium dioxide, nor to  emulsion paints. The pigment content of  coating materials can also be determined  by an ashing method (see EN ISO  14680-2) and by a filtration method (see EN ISO 14680-3).

Peintures et vernis - Détermination de la teneur en pigment - Partie 1: Méthode par centrifugation (ISO 14680-1:2000)

L'ISO 14680-1:2000 fait partie d'une série de normes traitant de l'échantillonnage et des essais des peintures, vernis et produits assimilés.
Elle spécifie une méthode pour déterminer la teneur en pigments des peintures, dans laquelle les solides sont sédimentés par centrifugation.
Elle est tout d'abord destinée à vérifier la composition pendant la production des matériaux de revêtement, et à faciliter le contrôle réception pour l'utilisateur du matériau de revêtement. Des difficultés peuvent apparaître lorsque la méthode est appliquée à des matériaux de revêtement contenant des colorants, du noir de carbone, du dioxyde de silicium très finement fractionné ou du dioxyde de titane très finement fractionné. Elle peut ne pas être appropriée pour les peintures émulsions.
La teneur en pigments des matériaux de revêtement peut également être déterminée au moyen d'une méthode par calcination (voir l'ISO 14680-2) ou d'une méthode par filtration (voir l'ISO 14680-3).

Overview

EN ISO 14680-1:2006 - Paints and varnishes: Determination of pigment content - Part 1: Centrifuge method specifies a laboratory test method to determine the pigment (and extender) content of coating materials by sedimenting the solids with a centrifuge. Published by CEN as an endorsed version of ISO 14680-1:2000, this standard is intended primarily for production control and acceptance testing of solvent- and some water‑dilutable paints (it may be unsuitable for emulsion paints and certain finely divided or coloured materials).

Key topics and requirements

  • Scope and principle: Dilute a representative test portion with a suitable solvent, separate insoluble solids by centrifugation, dry the sediment and calculate pigment content by mass.
  • Apparatus: laboratory centrifuge (balanced swivelling buckets) capable of 250 000 RPM-equivalent centrifugal acceleration (25 000 g), centrifuge tubes (e.g., 50 ml), polished-ball stirrer, forced‑air drying oven at (125 ± 2) °C, analytical balance (0.001 g) and desiccator.
  • Test portions and solvent volumes: Example table entries - 50 ml tube: 10 ± 0.2 g sample + ~20 ml solvent; 100 ml tube: 15 ± 0.3 g sample + ~40 ml solvent.
  • Procedure highlights:
    • Prepare representative samples per ISO 15528 and ISO 1513.
    • Dissolve binder with appropriate solvent (e.g., xylene for solvent‑soluble, butylglycol for water‑dilutable).
    • Centrifuge until supernatant is nearly clear (typically ~20 min), decant, resuspend and repeat 2–4 times.
    • Dry to constant mass at 125 °C, cool in a desiccator and weigh.
  • Calculation: Pigment content (%) = (m2 − m0) / (m1 − m0) × 100, where m0 = mass of empty tube, m1 = mass of tube + test portion, m2 = mass of tube + dried residue.
  • Precision: For ~30% pigment content - repeatability r = 2% (95% probability, same lab/operator); reproducibility R = 4% (different labs).
  • Test report must include product identification, reference to EN ISO 14680-1, solvent used, individual and mean results, deviations from the method and test date.

Applications

  • Quality control during paint and varnish production to monitor pigment/load levels.
  • Incoming inspection and acceptance testing by paint formulators, converters, and specifiers.
  • Laboratory verification when comparing formulations or troubleshooting pigment dispersion and solids content.
  • Note: exercise caution with samples containing dyestuffs, carbon black, very finely divided SiO2 or TiO2.

Related standards

  • ISO 14680-2 - Ashing method for pigment content.
  • ISO 14680-3 - Filtration method for pigment content.
  • Normative references used: ISO 1513 (sample preparation) and ISO 15528 (sampling).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
