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. 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. 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.

The committee responsible for this document is ISO/TC 17, Steel, Subcommittee SC 20, General technical

delivery conditions, sampling and mechanical testing methods.

Where the delivery requirements agreed upon for the order or specified in the appropriate product or

material standard differ from the general technical delivery requirements defined in this International

Standard, then it is the requirements agreed for ordering or specified in the appropriate product or

material standard that apply.

4 Information to be supplied by the purchaser

4.1 The purchaser shall select the steel type, the shape of the product and the dimensions, taking the

intended processing and use into account. The purchaser may consider the manufacturer’s advice in

making the choice.

The order shall provide all the information necessary for describing the product and its characteristics,

and also details concerning delivery such as
a) mass, length, area, number of pieces to be delivered;
b) the product form (it can be a number referring to a drawing, for example);
c) the nominal dimensions;
d) the tolerances on the characteristics in items a) and c);
e) the designation of the steel;
f) delivery condition (type of heat treatment, surface treatment etc.);
g) specific requirements for surface and/or internal quality (see 7.4);

h) the type of inspection document required and, where not specified in the product standard, the

4.2 The information in 4.1 shall be specified either
a) by reference to one or more International Standards, or

b) in the absence of an International Standard, by stipulation of the characteristics and conditions required.

If, in an order, reference is made to a given International Standard without specifying its edition date,

this reference shall be interpreted as being the edition current at the date of order acknowledgement.

6 Supply by an intermediary

The intermediary shall submit to the purchaser, the manufacturer’s inspection documents in accordance

with ISO 10474.

This documentation from the manufacturer shall be accompanied by suitable means of identification

of the product, in order to ensure the traceability between the product and the documentation (see

Clause 10).

If the intermediary has changed the dimensions of the product, the intermediary shall supply an

additional document for these particular new conditions. This also applies to all special requirements

given in the order and not defined in the manufacturer’s documentation.

Any organization which during processing changes the metallurgical state of the product is considered

as a product manufacturer.
7 Requirements
7.1 General
The product shall comply with the requirements of the order.

The manufacturer shall carry out appropriate process control, inspection and testing to verify that the

delivery complies with the requirements of the order, irrespective of the type of inspection document

required (see Clause 8).
7.2 Chemical composition

Requirements concerning the chemical composition shall be considered to refer to the cast (heat)

analysis unless they refer expressly to the product analysis.
7.3 Mechanical properties
7.3.1 Effect of dimensions

Where, in the product standard, the mechanical properties are specified by dimensional categories

such as thickness, diameter etc., the dimension that shall be considered is the nominal dimension of the

product at the prescribed location for taking samples for mechanical tests.
7.3.2 Applicable material condition

In the absence of any specification in the order or the product standard, the mechanical properties

relate to the as-delivered condition of the products.
7.3.3 Assessment of impact energy value

Where an impact-energy value is specified, without any further information, it shall be taken to represent

the average value of those individual tests that shall be assessed as described in 8.3.4.2.

7.4 Surface and internal quality
7.4.1 General

All products shall have a finish appropriate to the manufacturing route. Minor surface and internal

imperfections that can occur under normal manufacturing conditions shall not be grounds for rejection.
