Each member body interested in a subject for which a technical committee has been established has the right to be repr

IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards ar

Publication as an International Standard requires approval by at least 75 % of the member bodies casting a
24、 vote. Attention is drawn to the possibility 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. International Standard IS0 3252 was prepared by Technical Committee ISOTTC 1 19,

Powder metallurgy is the branch of metallurgy which relates
32、 to the manu- facture of metallic powders, or of articles made from such powders with or without the addition of non- metallic powders, by the application of forming and sintering processes. The terms are classified under the following main headings: 1 Powders 2 Forming 3 Sintering 4 Post-sintering
33、treatments 5 Powder metallurgy materials An alphabetical index of the terms defined is also given. NOTE 1 In addition to terms and definitions used in Eng- lish and French, two of the official IS0 languages, this Inter- national Standard gives the equivalent terms and definitions in the German langu
34、age; these are published under the re- sponsibility of the member body for Germany (DIN). How- ever, only the terms and definitions given in the official languages can be considered as IS0 terms and definitions. NOTE 2 Additional information on certain of the terms de- fined can be found in the stan
35、dards given in parentheses at the end of certain definitions. These are listed in the Bibliog- raphy. l) In English, the abbreviations PM and P/M are often used for powder metallurgy, as in “PM part”, “P/M prod- uct”, “PM process”.
