6. Responsibilities

   1. Purchaser

The purchaser shall be responsible for furnishing the manufacturer with a specification of the normal working conditions of the boiler plant (see also guides of procurement EN 45510-3-1 and EN 45510-3-3 where applicable), together with details of any transient and/or adverse conditions under which the boiler plant is required to operate and of any special requirements to facilitate in-service inspection.

The manufacturer shall be responsible for the completeness and accuracy of all design calculations and for compliance with all applicable requirements of this standard for the boiler assembly.

Manufacturers shall ensure that the execution of the provisions of this European Standard is entrusted to appropriately qualified and experienced personnel.

Duties carried out by other responsible authorities shall not absolve the manufacturer from his responsibility for compliance with the applicable requirements of this standard.

The offices, workshops and sites associated with the design and construction of water-tube boilers shall be properly equipped and shall have appropriate provisions for all the inspection and testing specified in EN 12952-6:2011. Manufacturing and other procedures shall be adequate and manufacturing personnel shall be competent and properly qualified for their assigned tasks.

The manufacturer shall be competent to manufacture the boiler in accordance with this standard (see EN 12952-5:2011, Annex F).

7. Design/type appraisal of pressure parts

The manufacturer is required to declare that the technical design specification and supporting documentation is in compliance with the requirements of this standard.

Because of the wide range of types of water-tube boiler plant that can be designed and manufactured in accordance with this standard, it has been recognized that it is not possible to cover all the combinations of situations that might arise. This might be due to the normal lag in time scale which naturally exists between standardization and advancing technology. In order not to inhibit progress in these circumstances, general guidance has been given within this European Standard to cover such situations. The specific requirements shall be determined by the manufacturer on a case-by-case basis according to the particular design and manufacturing details involved, ensuring, in all cases, the safety of the boiler will not be impaired.

It has also been recognized that during the manufacturing stages, unexpected factors might arise which require the introduction of design modifications and/or manufacturing concessions resulting in deviations from the specified requirements included at the initial design/type appraisal stage. Such deviations are permitted by this standard where it can be established that the safety and required function of the component are not impaired. Any such deviations shall be included in the technical documentation and form part of the manufacturer's data dossier.

Annex A

Significant technical changes between this European Standard and the
previous edition

Annex ZA
(informative)

Relationship between this European Standard and the Essential
Requirements of EU Directive 2014/68/EU

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential 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 and has been implemented as a national standard in at least one Member State, compliance with the clauses of this standard given in Table ZA.l confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations.
