Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 2014/68/EU (PED) aimed to be covered
This European Standard has been prepared under a Commission’s standardization request M/601 to
provide one voluntary means of conforming to Essential Safety Requirements of the New Approach
Pressure Equipment Directive 2014/68/EU.
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZA.1 and application of the
edition of the normatively referenced standards as given in Table ZA.2 confers, within the limits of the
scope of this standard, a presumption of conformity with the corresponding Essential Safety
Requirements of that Directive and associated EFTA regulations.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 second edition cancels and replaces the first edition (ISO 15614-11:2002), which has been technically
revised.
The main changes are as follows:
— normative references updated and ISO 15607 moved to Bibliography;
— acceptance level changed to quality level in accordance with the ISO 13919-1 and ISO 13919-2;
— terminology aligned with that used in other parts of the ISO 15614 series, where appropriate;
— figures updated and corrected, including symbols and keys;
— Tables 1 to 4 revised;
— 6.2 reformatted and revised;
— Clause 7 revised.
A list of all parts in the ISO 15614 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

Introduction
All new welding procedure tests are intended to be carried out in accordance with this document. However,
this document does not invalidate previous welding procedure tests made to former national standards or
specifications or previous editions of this document.
Where additional tests have to be carried out to make a qualification technically equivalent, these should be
done on a test piece which is made in accordance with this document.
Specification and qualification of WPSs that were made in accordance with previous editions of this
document can be used for any application for which the current edition is specified. In this case, the ranges
of qualification of previous editions remain applicable.
It is possible to create a new welding procedure qualification record (WPQR) range of qualification
according to this edition based on an existing qualified WPQR, provided the technical intent of the testing
requirements of this document have been satisfied.

1 Scope
This document specifies requirements for qualification testing of welding procedure specifications (WPSs)
for electron or laser beam welding.
This document applies to metallic materials, irrespective of the shape of the parts, their thicknesses, the
manufacturing method (e.g. rolling, forging, casting, sintering) or their heat treatment. It covers both the
production of new parts and repair work.
