Additionally to those requirements, the manufacturer shall ensure that: a) the organisation for the control of manufacturing operations which includes special processes such as welding, forming and heat treatment shall be clearly defined by the manufacturer; b) the manufacturing procedures such as welding, forming and heat treatment are adequate for the purpose and the pressure vessel meets the requirements of this standard. Where specific requirements are associated with materials these shall be taken into account, e.g. EAMs;
c) the manufacturing equipment is adequate for fabrication; d) the staff is adequate for the assigned tasks; NOTE As far as welding co-ordination is concerned, the qualifications, tasks and responsibilities can be defined by the manufacturer in accordance with EN ISO 14731:2007 [1] in the job assignment. e) the quality requirements for welding defined in EN ISO 3834-3:2005 are met as a minimum. 3.2 Subcontracting The manufacturer may subcontract work, but shall ensure that the subcontractor carries out the work in accordance with the requirements of this European Standard. The manufacturer is responsible for the adequate definition of the subcontracted task and the need for any associated records. On all occasions that the subcontractor work includes a) welding; b) forming including associated heat treatment; c) post weld heat treatment; d) non-destructive testing of welds (see EN 13445-5:2009), the manufacturer shall obtain a subcontractor form (see Annex B). Where welding operations are subcontracted, the manufacturer shall also either obtain copies of the welding procedure and welding operator qualification records or take other action to ensure that they comply with this standard.

EN 13445-4:2009 (E) Issue 1 (2009-07) 8 In discharging his responsibility to ensure that the subcontractor carries out the work in accordance with this standard the manufacturer shall ensure that surveillance of the subcontracted work is performed. Where a manufacturer is producing equipment that requires the intervention of a responsible authority, the manufacturer should inform the responsible authority of his intention to subcontract so that the responsible authority has the opportunity to take part in the subcontractor surveillance. NOTE 1 See also EN 764-3:2002, 2.11 [2] and CR 13445-7. NOTE 2 When the manufacturer is producing equipment based on quality assurance, the controls a manufacturer applies over subcontractors should be described in his approved quality system.
4 Materials 4.1 General Materials for pressure vessels and the grouping of materials for pressure vessels shall be in accordance with EN 13445-2:2009. The grouping applies regardless of product form, i.e. plate, forging, piping. 4.2 Material traceability 4.2.1 General The vessel manufacturer shall have and maintain an identification system for materials used in fabrication, so that all material subject to stress due to pressure and those welded thereto in the completed work can be traced to its origin. This includes the use of welding consumables. 4.2.2 Identificati
