ISO 11127‑3 is the third part of the ISO 11127 multi-series, and discusses steel substrates. ISO 11127‑3 specifies a method for the determination of the apparent density of non-metallic blast-cleaning abrasives. These abrasives are used for steel substrate preparation before it is painted.
ISO 11127‑3 deals with the sampling and testing of non-metallic abrasives for blast cleaning steel substrates so that they are ready to be painted.
Note 1: The types of non-metallic abrasives and requirements for each are contained in the ISO 11126 series.
Note 2: The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives.
ISO 11127‑3 on steel substrate preparation before application of paints is useful for:
Apparent density is one method of calculating the particle sizes of abrasives. If the apparent density is low, it means that the abrasive consists of finer/small particles. If the apparent density is high, it means that the abrasive consists of large-sized particles.
ISO 11127‑3 provides you with a pycnometer method for the determination of the apparent density of non-metallic blast-cleaning abrasives. ISO 11127‑3 guides you through the test procedure to ensure the classification and segregation of non-metallic abrasives based on their apparent density.
