18、ISO 16120-2:2017(E)ForewordISO (the International Organization 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 sub
19、ject 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 the International Electrotechnical Commission (I
20、EC) 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 the different types of ISO documents should be
21、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. ISO shall not be held responsible for identi
22、fying 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).Any trade name used in this document is information given for the conven
23、ience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see th

30、tes the values to be inserted by the purchaser according to the steel names designated in Table 1, first column.The designations of comparable steel grades in national or regional standards are provided in Annex A.Steels can also be ordered according to tensile strength. The mid-point of the require
31、d ultimate tensile strength (UTS) range shall be indicated as a suffix to the grade designation, e.g. C#D 1020, where the required mid-point of the UTS is 1 020 MPa. “#” means “to be left blank” since the carbon content is at the discretion of the supplying mill, and the supplying mill indicates the
32、 exact number of # based on the grade designation until shipment. See Table 1 for the grade designation.1) Under preparation. Stage at the time of publication: ISO/FDIS 16120-1:2016.
