ISO 11125-3 Test Methods for Metallic Spray Cleaning Abrasives - Determination of Hardness

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 11125-3 testing. This standard specifies a test method for determining the Vickers hardness of metallic blast cleaning abrasives.

This is one of a series of sections of ISO 11125 dealing with sampling and testing metallic abrasives for blast cleaning. The types of metallic abrasives and the requirements for each are contained in the various sections of ISO 11124.

The hardness of metallic blasting abrasives is an important property as it affects the quality of the surface preparation and subsequent coating application. Hardness is defined as the abrasive's resistance to deformation and is measured by determining the depth of an indentation made by a diamond drill under a given load.

ISO 11125-3 specifies equipment and procedures for performing hardness testing, including preparing test specimens, applying load, and measuring indentation. Test results are reported as the Vickers hardness number calculated based on the dimensions of the indentation.

This standard is intended for use by manufacturers and users of metallic blasting abrasives, as well as by testing laboratories and regulatory authorities. It provides a standardized method for determining the hardness of metallic abrasives that can help ensure the consistency and quality of surface preparation processes.
