Foreword
This document (EN 764-4:2014) has been prepared by Technical Committee CEN/TC 54 “Unfired pressure
vessels”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the latest by
June 2015.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 764-4:2002.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive.
For relationship with EU Directive 97/23/EC (PED), see informative Annex ZA, which is an integral part of this
document.
Regarding the most significant technical changes that have been implemented in this new edition of EN 764-4,

1 Scope
This European Standard specifies the requirements, under the regime of the EU Directive 97/23/EC on Pressure
Equipment (PED), for the establishment of the technical delivery conditions in the form of:
— harmonized European Standards for material;
— European Approval for Materials (EAM);
— Particular Material Appraisal (PMA)
for metallic materials for pressure equipment in all product forms. Welding consumables are not covered by this
standard.
This European Standard was developed predominantly on the basis of steel, nickel and nickel-based materials.
However, application to other materials is not restricted but should consider specific aspects relevant to the
material concerned.
