BS EN ISO 11126-8:2018

This standard BS EN ISO 11126-8:2018 Preparation of steel substrates before application of paints and related products. Specifications for non-metallic blast-cleaning abrasives is classified in these ICS categories:

• 25.220.10 Surface preparation

This document specifies requirements for olivine abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides.

The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use.

Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127.

NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504‑2.
