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, 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

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 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.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

URL: www .iso .org/ iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 17,Steels, Subcommittee SC 3, Steels for

structural purposes.

This second edition cancels and replaces the first edition (ISO 630-1:2011), which has been technically

revised. The main changes compared to the previous edition are as follows:
― List of normative references has been updated.

― In Tables, the designations concerning thickness have been changed to “nominal thickness”.

― ISO 657-16 has been deleted from Normative references and the text in 6.7.1.

― Terms and definitions of “non-specific inspection” and “specific inspection” have been deleted,

because ISO 404 and ISO 10474 have been added in Normative references.
― Designation of qualities has been added.
― List of options has been updated.
― Content of Table A.1 has been updated.
― The bibliography has been updated

― The content of the document has been updated to harmonize with all parts of ISO 630.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 630-1:2020(E)
Structural steels —
Part 1:
General technical delivery conditions for hot-rolled
products
1 Scope

This document specifies the general technical delivery conditions for steel flat and long products

(plates/ sections/wide flats and bars) used principally for general-purpose structural steels. The steels

specified in this document are intended for use in welded or bolted structures.

The specific requirements for structural steels are given in the individual parts of ISO 630.

This document does not include the following structural steels, some of which are covered by other

International Standards:

— sheet and strip: refer to ISO TC 17/SC 12 “Continuous mill flat rolled products”;

— tubular products: refer to ISO TC 5/SC 1 “Steel tubes”.

NOTE 1 Lists of standards covered by ISO/TC 17/SC 12 and ISO/TC 5/SC 1 are available on the ISO Web site.

NOTE 2 In all parts of ISO 630, the term of "thickness" is considered as "nominal thickness", unless

otherwise stated.
