    19、on 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 a technical committee has been established ha

    20、s 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 matters of electrotechnical standardization. The

    21、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 document was drafted in accordance with the edi

    22、torial 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 such patent rights. Details of any patent

    23、 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 does not constitute an endorsement. Fo

This second edition cancels and replaces the first edition (ISO 683-5:2014), of which it constitutes a minor revision. The main changes compared to

    26、the previous edition are as follows: in the Scope, “see 5.2” has been added as a cross reference; in 3.1, note 1 to entry has been revised; in 5.2, the ordering example has been moved into a new subclause, as 5.3; in 7.7.3, the surface class given has been changed from A to 1z2; in 9.2.3, the option

    27、 for retesting has been revised; Figure 3 has been renamed as Table 9; in A.2.1, the cross references have been corrected to A.2.2 to A.2.4.

    29、 manufactured from the nitriding steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1, rows 2 to 5, and in one of the surface conditions given in Table 2. The steels are generally intended for the fabrication of quenched a

    30、nd tempered and, subsequently, nitriding machine parts. The requirements for mechanical properties given in this document are restricted to the sizes given in Table 6. NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are in the

    31、following covered under semi-finished products or bars and not under the term “hammer and drop forgings”. NOTE 2 The term “plate” includes in the following also wide flats unless otherwise stated. In special cases, variations in these technical delivery requirements or additions to these requirement

    32、s can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B). In addition to this document, the general technical delivery requirements of ISO 404 are applicable. 2 Normative references The following documents are referred to in the text in such a way that some or al
