The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with Iso, also take part in the work. Iso collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the IsO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 9136-1 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 5, Grinding wheels and abrasives. This first edition of IsO 9136-1 cancels and replaces IsO 9136:1989, the contents of which have been technically revised. density: Part 1: Macrogrits Part 2: Microgrits ii Copvriaht International Oraanization for Standardizatior INTERNATIONAL STANDARD ISO 9136-1:2004(E) Abrasive grains Determination of bulk density - Part 1: Macrogrits 1 Scope This part of IsO 9136 specifies a test method for the determination of the bulk density of bonded and coated abrasive macrogrits.
