27、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 a technical committee has been established has the right to be represented on that committee. International

28、 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 matters of electrotechnical standardization.International Standards are drafted in accordance with the rules gi

29、ven in the ISO/IEC 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

33、. The methods described in this part do not yield the true mean grain diameter, but a somewhat smaller parameter depending on the method applied to analyse a two-dimensional section. The relationship to true grain dimensions depends on the grain shape and the degree of microstructural anisotropy. Th

34、is part contains two principal methods, A and B.Method A is the mean linear intercept technique. Method A1 applies to single-phase ceramics, and to ceramics with a principal crystalline phase and a glassy grain-boundary phase of less than about 5 % by volume for which intercept counting suffices. Me

35、thod A2 applies to ceramics with more than about 5 % by volume of pores or secondary phases, or ceramics with more than one major crystalline phase where individual intercept lengths are measured, which can optionally be used to create a size distribution. This latter method allows the pores or phas

36、es to be distinguished and the mean linear intercept size for each to be calculated separately.NOTE A method of determining volume fraction(s) of secondary phase(s) can be found in ISO 13383:2; this will provide a means of determining whether Method A1 or Method A2 should be applied in borderline ca

37、ses.Method B is the mean equivalent circle diameter method, which applies to any type of ceramic with or without a secondary phase. This method may also be employed for determining grain aspect ratio and a size distribution.Some users of this part of ISO 13383 may wish to apply automatic or semiauto

38、matic image analysis to micrographs or directly captured microstructural images. This is permitted by this part provided that the technique employed simulates the manual methods (see Clause 4 and 8.4).2 Normative referencesThe following referenced documents are indispensable for the application of t

45、ain size characterization is an important tool for ensuring consistency of manufacture. There are many measures of grain size and/or shape, and these are usually of different numerical values for a given microstructure.NOTE The Bibliography contains sources dealing with stereology and methods of siz

46、ing three-dimensional objects.The principal purpose of this part of ISO 13383 is to permit characterization of the major phases. However, in materials which contain more than one phase, the phases may be continuous or as isolated grains. It may be necessary to characterize the different phases separ

47、ately. The same intercept principle as for single-phase materials can be used, but the individual intercept lengths across each phase must be measured, rather than just counted. The characterization of minor phases may require different treatment, which is outside the scope of this part of ISO 13383

48、.Method A, the linear intercept method, provides the simplest possible method from a two-dimensional section through the material. However, it must be recognized that the numerical value obtained for the mean linear intercept size is somewhat smaller than most other measures of grain size because intercepts can cross grains at any position, and not necessarily along the largest axis. The relationship between mean linear intercept size and a t
