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 of 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 www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 10, Quality management in the field of welding, in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 3834-2:2005), of which it constitutes a
minor revision.
The main changes compared to the previous edition are as follows:
— editorial revisions;
— update of references to the latest edition of ISO 3834-5;
— rewrite of Clause 16 on calibration and validation of measuring, inspection and test equipment.
A list of all parts in the ISO 3834 series can be found on the ISO website.

5 Review of requirements and technical review
5.1 General
The manufacturer shall review the contractual requirements and any other requirements, together
with any technical data provided by the purchaser or in-house data when the construction is designed
by the manufacturer. The manufacturer shall establish that all information necessary to carry out
the manufacturing operations is complete and available prior to the commencement of the work. The
manufacturer shall affirm its capability to meet all requirements and shall ensure adequate planning of
all quality-related activities.
The review of requirements is carried out by the manufacturer to verify that:
— the work content is within its capability to perform,
— sufficient resources are available to achieve delivery schedules and
— documentation is clear and unambiguous.
The manufacturer shall ensure that any variations between the contract and any previous quotation are
identified and the purchaser notified of any programme, cost or engineering changes that can result.
Items in 5.2 are typically considered at or before the time of the review of requirements. Items in 5.3
usually form part of the technical review and are considered during the initial planning stage.
When a contract does not exist, e.g. items made for stock, the manufacturer is required to take into
consideration the requirements of 5.2 while carrying out the technical review (see 5.3).
5.2 Review of requirements
The following aspects shall be considered:
a) the product standard to be used, togeth
