Steel and steel products -- General technical delivery requirements
ISO 404:2013 specifies the general technical delivery requirements for all steel products covered by ISO 6929, with the exception of steel castings and powder metallurgical products. ISO 10474 describes the inspection documents to be used. 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 ISO 404:2013, then it is the requirements agreed for ordering or specified in the appropriate product or material standard that apply.

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/directivesAttention 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/patentsAny 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.This third edition cancels and replaces the second edition (ISO 404:1992), which has been technically revised.

requirements
1 Scope
This International Standard specifies the general technical delivery requirements for all steel products
covered by ISO 6929, with the exception of steel castings and powder metallurgical products.
ISO 10474 describes the inspection documents to be used.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.2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.ISO 377, Steel and steel products — Location and preparation of samples and test pieces for mechanical testing

for submission to a given testNote 1 to entry: See Figure 1.

3.12
product analysis
chemical analysis carried out on the product
3.13

them without further processing or after processing without changing the properties specified in the
purchase order and referenced product specificationNote 1 to entry: Examples of intermediaries can be steel service centres and stockists.
4 Information to be supplied by the purchaser4.1 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 asa) 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
inspection and testing requirements (see Clause 8);i) where applicable, the application of the quality management systems given in ISO 9001;
j) requirements for marking, packaging and loading;k) any optional (supplementary) requirements provided for by the product standard.

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.
5 Manufacturing processThe manufacturing process shall be left to the discretion of the manufacturer, unless otherwise agreed

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 quality7.4.1 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.
