40、-09 ForewordISO (the International Organization for Standardization) is a worldwide federation of national 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
41、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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matt
42、ers of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This doc
43、ument was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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 s
44、uch patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and do

46、ationThe committee responsible for this document is ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic materials.This second edition cancels and replaces the first edition (ISO 22674:2006), which has been technically revised with the following changes: Corrosion resistance measurement was refer
47、red to the recent standard ISO 10271:2011. A second tarnish test was included, referring to provisions in ISO 10271:2011. Clarification of the term “free of“ was added to the requirements of composition and labelling; Lead was added as a hazardous element. Measurement of elasticity was revised. Besi
48、de the method of calculation of elastic modulus using an extensometer, other alternative methods were added, namely, the flexure method in three- and four-point bending and the acoustic resonance method. Informative Annex A was added, dealing with tensile testing of non-cast Type 0 metallic material
49、s intended for use in a thickness between 0,1 and 0,5 mm. Normative Annex B was added, giving information on calculation of uncertainty for elastic measurement. Informative Annex C was added, giving information for measurement of Poisson ratio.5EN ISO 22674:2016 (E)DIN EN ISO 22674:2016-09 IntroductionSpecific qualitative and quantitative requirements for freedom from biological hazard are not included in this International Standard
