ISO 15461:2018 鋼鍛造品—機械的試験の試験頻度、サンプリング条件、および試験方法 | ページ 2

Foreword

ISO (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 subject 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 (IEC) 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, 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 editorial rules of the ISO/IEC Directives, 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 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.

This document was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 10 Steel for pressure purposes.

This first edition of ISO 15461 is based on Technical Report ISO/TR 15461:1997, which has been withdrawn. The main changes are as follows:

• Figures 3 a) and b) have been revised;
• Table 3 has been revised;
• Table 5 has been extended to steels for pressure purposes;
• the text of the document has been generally revised.

1 Scope

This document gives guidelines for the simplification and harmonization of the specifications for mechanical testing of open die and closed die forgings in International Standards and other technical delivery conditions for forgings of steel.

This document

• a) offers various options for
  • 1) the frequency of testing, and
  • 2) sampling conditions,

• b) introduces a designation system for the options, mentioned under (a), and

• c) specifies the test methods for

  • 1) room temperature tensile tests,
  • 2) elevated temperature tensile tests,
  • 3) impact tests, and
  • 4) uniformity checks by hardness tests.
