Metal Particle Testing Standards
Metal Particle Testing covers metallic powders, metal surface inspection, and magnetic particles. Aluminium oxide (alumina) also gets special mention, as does the preparation of steel substrates before the application of paints and related products. The analysis of metal surfaces for particles provides a range of useful information, and many standards have been developed to cover the various industrial procedures that take advantage of this.
