24、S0 qbq3-ENGL 2000 Lb24bb9 OB8007b 3b0 W EN IS0 9693:2000 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committee
25、s. 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 non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the Inter
26、national Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodie
27、s for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 9693 was prepared by Technical Committee ISOTTC 106, Dentistry, Subcommittee SC 2, Prosthodontic materials. Attention is drawn to the possibility
28、that some of the elements of this International Standard may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. This second edition cancels and replaces the first edition (IS0 9693:1991), which has been technically revised. Significant d
29、ifferences between this second edition and the first edition are: - the scope includes metallic materials (not only alloys) processed by casting or machining; - a requirement (4.3.3) and a test (6.3.3) on the debondingkrack-initiation strength for the metal-ceramic system have been added, replacing
30、the previous requirement and test related to metal-ceramic bond characterization. iv Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- STD=BSI BS EN IS0 9693-ENGL 2000 M 1624669 0
31、880077 2T7 = EN IS0 9693:2000 Introduction Dental metallic materials and ceramics are suitable for use in fabrication of metal-ceramic dental restorations. Specific qualitative and quantitative requirements for freedom from biological hazards are not included in this International Standard, but it i
32、s recommended that, in assessing possible biological hazards, reference be made to IS0 10993-1 and IS0 7405. Requirements and test methods for tarnish and corrosion resistance for the components and for the metal-ceramic system will be included in the future when they are available. V Copyright Euro

34、 specifies requirements and test methods for dental metallic materials processed by casting or machining, and for ceramics suitable for use in the fabrication of metal-ceramic dental restorations, together with requirements and test methods for the composite structure. The requirements of this Inter
35、national Standard apply to the metallic materials and ceramics when used in combination, and compliance may not be claimed for either metallic materials or for ceramics alone. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitut
