9、S ISO 525:2013ISO 525:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intereste

10、d in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Com

11、mission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents

12、should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

15、ows:a) clarification has been included in the Scope to explicitly exclude coated abrasive products;b) a note has been included in Clause 4 on the relationship with the ISO 603 series and the dimensional requirements given there;c) in Clause 4, Table 2, the description of some existing types of bonde

16、d abrasives products has been changed and type numbers 17, 17R, 19R, 29 and 40 have been included;d) all specific requirements on dimensions (outside diameter, thickness and bore diameter) have been removed from Clause 5 and reference is now made to the ISO 603 series;e) in Clause 5, requirements fo

17、r maximum operating speeds have been deleted;f) Clause 6 on designation has been reworded and included in Clause 5;g) additional marking requirements have been included.iv ISO 2013 All rights reservedBS ISO 525:2013INTERNATIONAL STANDARD ISO 525:2013(E)Bonded abrasive products General requirements1

18、ScopeThis International Standard is applicable to bonded abrasive products (e.g. grinding wheels, segments, sticks and stones) in general, excluding superabrasive products and coated abrasive products.This International Standard specifies:a) the ISO type number and shape;b) dimensional symbols;c) st

19、andard profiles;d) requirements for dimensions, limit deviations and tolerances as well as permissible unbalance;e) the specification mark; f) the marking requirements.NOTE This International Standard is general and is complemented by the ISO 603 series, ISO 6103 and ISO 13942.2 Normative references
