20、es). 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, governmental and

21、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 Directives, P

22、art 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 casti

23、ng 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 3107 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 1, Fil

This third edition cancels and replaces the second edition (ISO 3107:1988), which has been technically revised, including extensive revision and simplification of the classification system, and removal of the disintegration limit as a requirement for temporary cements

36、23 1) C and a relative humidity of (50 5) %. Before the start of mixing, condition the test samples and apparatus in these conditions for at least 1 h. Prepare the cement according to the manufacturers instructions. Mix sufficient cement to ensure that the preparation of each specimen is completed f

Place the metal mould (6.2.1.3), conditioned at (23 1) C, on a flat glass plate (6.2.1.5) and fill with the cement to give a level top surface. At (120 10) s after the start of mixing for Type III ceme

42、nts, or (180 10) s from the start of mixing for other cements, place the specimen on the metal block in the cabinet. As soon as possible after placing the specimens in the cabinet, carefully lower the indenter needle vertically onto the surface of the cement. Make indentations at 15 s intervals with

43、 no superimposition of indentations until the time of setting has been reached. Maintain the needle tip in a clean condition between indentations. Record the setting time, to the nearest 15 s, as the period of time which elapses from the start of mixing to the time when the needle fails to penetrate
