17、O 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. International organizations, gove
18、rnmental 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. International Standards are drafted in accordance with the rules given in the ISO/IEC
19、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
20、 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 11143 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommi

This second edition cancels and replaces the first edition (ISO 11143:1999) which has been technically revised by means of the following changes: a) the description of the test method has been improved; b) testing at a minimum flow rate for certain types of separator is
22、now required; c) updated labelling requirement has been introduced.

23、-,- ISO 11143:2008(E) vi ISO 2008 All rights reserved Introduction Amalgam separators are items of dental equipment designed to retain amalgam particles carried by the waste water from the dental treatment centre, so as to reduce the number of amalgam particles and therefore the mass of amalgam ente
24、ring the sewage system. Separation of the amalgam particles may be effected by the use of a centrifuge, sedimentation, filtration, or a combination of any of these methods. It is recognised that the test sample used to assess the efficiency of an amalgam separator should have a particle size distrib
