It supersedes BS ISO 15490:2000 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee RPI/13,Advancedtechnical ceramics. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract.

Each member body interested in a subject for which a technical committee has been 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.
