7、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 a technical committee has been established has the r

8、ight 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 matters of electrotechnical standardization. Internation

9、al Standards are drafted in accordance with the rules given 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

10、 an International Standard requires approval by at least 75 % of the member bodies casting 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.

14、ed refractory products of the alumina-silica series, with the following exceptions: a) products containing more than of any metallic oxide other than alumina, silica, iron oxide; b) products containing more than carbon, carbides, nitrides, oxynitrides or any associated materials. 2 Classification 2.

15、1 Basis of classification Dense shaped refractory products of the alumina-silica series shall be classified according to the following five criteria: a) the type of product; b) the group determined by its alumina and/or silica contents; c) the principal raw material(s); d) the state of the raw mater

16、ial(s); e) the nature of the bond (including any post treatment). 2.2 Type of product The types of dense shaped refractory products of the alumina-silica series included in this classification are: a) high alumina (HA), b) fireclay (FC), c) low alumina fireclay (LF), d) siliceous (SS), and e) silica

17、 (SL). NOTE The abbreviations used in the above list are from the English names for the refractory products. These product types shall be classified in accordance with Table 1, by their chemical analysis carried out on the calcined test products. 1) 1) A chemical analysis standard is under developme

19、n in Ta b l e 1 . 2.4 Nature of raw materials Dense shaped refractory products of the alumina-silica series shall be classified by their principal raw material when the content is greater than or equal to , or by their two principal raw materials when the content is less than . EXAMPLES Some example

20、s of raw materials are as follows: corundum; bauxite; mullite; sillimanite and associated minerals (andalusite, kyanite); fireclay; quartzites and associated products (silica sand, fused silica). 2.5 State of raw materials The raw materials shall be classified by using one of the three designations,

21、 as follows: a) naturally occurring (raw or calcined); b) synthetic calcined; c) fused.

24、, formed by chemical reaction at ambient temperature or at a temperature below ; c) fusion cast, formed by total fusion of the product. NOTE 1 The ceramic bond may be either with or without impregnation after firing. NOTE 2 The inorganic chemical bond may be either with or without tempering at a tem

25、perature below . 3 Designation The designation of dense shaped refractory products of the alumina-silica series shall comprise the listing of the five classification criteria given in Clause 2: product type, group, nature of raw materials, state of raw materials, nature of the bond. EXAMPLES Some ex

26、amples of designations are as follows: high alumina product of the group HA 98, based on synthetic calcined corundum, with a ceramic bond; high alumina product of the group HA 75, based on naturally occurring calcined bauxite and sillimanite, with an inorganic chemical bond, tempered; high alumina product of the group HA 75, based on fused mullite, with a ceramic bond; fireclay product of the group FC 40, based on naturally occurring calcined fireclay, with a ceramic bond. 800 C 800 C 800 CISO 10081-1:2003(E) ICS 81.080 Price based on 3 pages ISO 2003 All rights reserved
