The work of preparing International Standards is normally carried out through ISO technical
9、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 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with
10、the International Electrotechnical Commission (IEC) on all matters 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
11、 the different types of ISO documents should be noted. This document 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
12、. ISO shall not be held responsible for identifying any or all such 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).

15、014Fine ceramics (advanced ceramics, advanced technical ceramics) Vocabulary1 ScopeThis International Standard is a vocabulary, which provides a list of terms and associated definitions typically used for fine ceramic (advanced ceramic, advanced technical ceramic) materials, products, applications,
16、properties, and processes. This International Standard contains, in separate lists, those abbreviations which have found general acceptance in the scientific and technical literature; they are given together with the corresponding terms and definitions or descriptions.In this International Standard,
17、 the terms are defined using the term “fine ceramic”. The definitions apply equally to “advanced ceramics” and “advanced technical ceramics”, which are considered to be equivalent.This International Standard does not include terms which, though used in the field of fine ceramics, are of a more gener
18、al nature and are also well known in other fields of technology.NOTE Terms and definitions of a more general nature are available in ASTM C 1145,1EN 14232,2and JIS R 1600.3A list of some International Standards and draft International Standards of ISO/TC 206 “Fine ceramics” containing terms defined
