It is within the remit of the responsible technical committee for materials to check at each occasion of the revision work whether related

46、 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 the

47、 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.

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 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 materia
