ISO 11126-9:1999

Preparation of steel substrates before application of paints and related products. Specifications for non-metallic blast-cleaning abrasives. Part 9 : staurolite.

This part of ISO 11126 specifies requirements for staurolite 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 part of ISO 11126 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 1 Information on commonly referenced national standards for non-metallic abrasives is given in annex A.

NOTE 2 Although this part of ISO 11126 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 8504-2:1992. Preparation of steel substrates before

application of paints and related products — Surface preparation methods — Part 2: Abrasive blast-cleaning.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
