TECHNICAL STANDARD
ISO 11127-2
Preparation of steel substrates before application of paints and related products — Test methods for non-metallic blast-cleaning abrasives — Part 2: Determination of particle size distribution
ISO
Edition 3 / 2020
Current
WHAT DOES THIS STANDARD COVER?
Specifies determination of particle-size distribution of non-metallic blast-cleaning abrasives by sieving.
WHY IS IT RELEVANT?
Relevant when checking abrasive characteristics against specification requirements as part of surface-preparation quality control.
KEY INSPECTION CONSIDERATIONS
The standard provides a method for determining the particle size distribution of non-metallic blast-cleaning abrasives by sieving. Particle size distribution can influence blasting behaviour and the surface produced. The method forms part of the wider ISO 11127 series for sampling and testing non-metallic abrasives. Results should be interpreted against the applicable abrasive specification rather than as a prepared-surface acceptance result.
WHAT THE STANDARD SHOULD NOT BE USED TO ASSUME
Particle size distribution does not independently establish visual surface cleanliness, surface profile or contamination condition. It represents one characteristic of the abrasive and should not be treated as demonstrating complete abrasive suitability or prepared-surface compliance.
PRACTICAL INSPECTION APPLICATION
The method can support abrasive qualification, receipt inspection or investigation where verification of particle size distribution is required. Inspectors should identify the abrasive sample and applicable specification and retain the result. Changes in abrasive grading can also be considered when investigating unexpected blasting performance, while the prepared surface should be assessed separately.
