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 3834-3:2005), 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.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

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 previ
