14、l standards bodies (ISO member bodies). 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 established has the right to be represented on that committee. Internation
15、al organizations, governmental and 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. Draft International Standards adopted by the technical committee
16、s 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. International Standard ISO 8486-1 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 5, Grinding wheels and abra

19、ISO 8486-1:1996 BSI 12-19981 1 Scope This part of ISO 8486 sets forth a method for determining or checking the size distribution of macrogrits from F4 to F220 in fused aluminium oxide and silicon carbide. It specifies the grit designation for the testing of those grits used in the manufacture of bon
20、ded abrasive products and general industrial applications and those removed from bonded products. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 8486. At the time of publication, the editions indicate
