General Paint Standards

General paint particle testing standards are published by ISO, ASTM, and ANSI. The ISO 9934 series includes non-destructive testing general principles, detection media, and equipment. ANSI publishes a standard for arts and crafts materials for ink and paints. ASTM publishes standard test methods, practices, and guides on chemical analysis of zinc dust, sampling for particulate contamination by tape lift, microspectrophotometry, and evaluating on-site extraction for lead. The other ISO documents cover determination of density, sample preparation, coating powders, and viscosity determination.

ISO 9934-1:2016

Non-destructive testing - Magnetic particle testing - Part 1: General principles

ISO 9934-1:2016 specifies general principles for the magnetic particle testing of ferromagnetic materials. Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities, particularly cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes rapidly with depth. ISO 9934-1:2016 specifies the surface preparation of the part to be tested, magnetization techniques, requirements and application of the detection media, and the recording and interpretation of results. Acceptance criteria are not defined. Additional requirements for the magnetic particle testing of particular items are defined in product standards (see the relevant International Standards or European standards). ISO 9934-1:2016 does not apply to the residual magnetization method.

It is not, however, suitable for textured paints which contain coarse particles.

ISO 14887:2000

Sample preparation -- Dispersing procedures for powders in liquids

This International Standard was developed to help particle size analysts make good dispersions from powder/liquid combinations with which they are not experienced. It provides procedures for wetting a powder into a liquid; deagglomerating the wetted clumps; determining if solution composition can be adjusted to prevent reagglomeration; selecting dispersing agents to prevent reagglomeration; evaluating the stability of the dispersion against reagglomeration. This International Standard is applicable to particles ranging in size from approximately 0,05 to 100 m. It provides a series of questions on the nature of the powder and liquid involved. The answers are used with charts that guide the user to generic dispersing agents that are likely to be suitable for dispersing the powder in the liquid. This International Standard applies only to the preparation of simple, dilute dispersions (less than 1 % by volume solids) for particle size analysis. It does not deal with the formulation of complex and commercial mixtures highly loaded with solids, such as paints, inks, pharmaceuticals, herbicides and composite plastics.

Coating powders - Part 10: Determination of deposition efficiency

This document specifies a method for determining the mass fraction in per cent (%) of a sprayed coating powder which is deposited on a test item under known spray gun and environmental conditions. The method is applicable to powders applied by corona or tribo charging and can be used to compare the deposition efficiency of different powders with the same or different gun with the same powder. This method is only used for comparison when powders or guns are evaluated consecutively, as the influence of the environment and the equipment can vary significantly with time and location.

ISO 8130-13:2019

Coating powders - Part 13: Particle size analysis by laser diffraction

This document specifies a method for the determination of the equivalent-sphere particle size distribution of coating powders by laser diffraction, for particles of the size range from 1 µm to 300 µm. NOTE There is a possibility that particle sizes 300 µm need the use of a different optical model. This document is specific for the measurement of coating powders and also draws attention to ISO 13320, which provides guidance on instrument qualification and particle size distribution. Laser diffraction is not suitable for determining oversize material, which can be verified by sieve analysis as described in ISO 8130 1 or by dynamic image analysis as described in ISO 13322 2.
