25、 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 i
26、n 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 mater
27、ial concerned. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、Harmonized European material standards under the regime of the PED define the technical requirements for materials frequently used in pressure equipment in Europe. It is within the remit of the responsible technical committee for materials to check at each occasion of the revision work whether relat
42、ed material grades covered by an EAM are used to an extent that justifies the incorporation of the grade into the relevant harmonized European material Standard. 4.2 European Approvals for Materials for pressure equipment (EAMs) A European approval for materials means a technical document defining t
43、he characteristics of materials intended for repeated use in the manufacture of pressure equipment, the type of which is not covered by any harmonized European material standard. According to Guiding Principles for the contents of EAM drafts, agreed by the Member States of the European Union and the
44、 European Commission, it shall i.a. describe material properties in a concise, complete and correct manner. The ways and means undertaken to achieve an EAM and a data sheet containing at least the applicable elements is given in Annex A. An EAM shall not be issued for: a) a grade of material listed
45、in a current or former national material standard that has a specification covered by a harmonized European material standard; b) a grade of material which is previously included in a European national material standard but which is not included in the harmonized European material standard which has
46、 replaced the European national material standard (ref. PED Guideline 7/26). NOTE 1 Reference of available EAMs is published in the Official Journal of the European Union (OJEU). NOTE 2 Actual EAMs are also published at the following website of the European Commission: http:/ec.europa.eu/enterprise/
47、sectors/pressure-and-gas/documents/ped/materials/index_en.htm. 4.3 Particular Material Appraisals for pressure equipment (PMAs) Particular material appraisals apply for individual cases as for example: a) a material grade or a product form or a thickness not covered by a harmonized European material
48、 standard, harmonized under the scope of the PED, or by an EAM; BS EN 764-4:2014EN 764-4:2014 (E) 9 b) a product specified in a harmonized European material standard for pressure purposes or in an EAM is intended in an exceptional case for service conditions outside its specified range of applicatio
49、n. For pressure equipment classified in category III and IV according to the PED, the PMA/PMAs, which irrespective of category (I to IV) always shall be drawn up by the equipment manufacturer, shall be appraised and confirmed by the Notified Body in charge of the conformity assessment for the actual piece of pressure equipment. Where relevant to the pressure equipment under consideration the requirements given in Annex B to Annex E together with EN 13445-2:2014, 4.1 and 4.2, may be used as guidance.
