European foreword
This document (FprCEN/TR 12952-17:2024) has been prepared by Technical Committee CEN /TC 269,
“Shell and water-tube boilers”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
EN 12952, Water-tube boilers and auxiliary installations consists of the following parts:
— Part 1: General;
— Part 2: Materials for pressure parts of boilers and accessories;
— Part 3: Design and calculation for pressure parts of the boiler;
— Part 4: In-service boiler life expectancy calculations;
— Part 5: Workmanship and construction of pressure parts of the boiler;
— Part 6: Inspection during construction; documentation and marking of pressure parts of the boiler;
— Part 7: Requirements for equipment for the boiler;
— Part 8: Requirements for firing systems for liquid and gaseous fuels for the boiler;
— Part 9: Requirements for firing systems for pulverized solid fuels for the boiler;
— Part 10: Requirements for safeguards against excessive pressure;
— Part 11: Requirements for limiting devices of the boiler and accessories;
— Part 12: Requirements for boiler feedwater and boiler water quality;
— Part 13: Requirements for flue gas cleaning systems;
— Part 14: Requirements for flue gas DENOX-systems using liquefied pressurized ammonia and ammonia
water solution;
— Part 15: Acceptance tests;
— Part 16: Requirements for grate and fluidized-bed firing systems for solid fuels for the boiler;
— Part 17: Guideline for the involvement of an inspection body independent of the manufacturer;
— Part 18: Operating instructions.
Although these parts can be obtained separately, it should be recognized that the parts are inter-
dependent. As such, the design and manufacture of water-tube boilers requires the application of more
than one part in order for the requirements of the standard to be satisfactorily fulfilled.
1 Scope
This document gives guidance for the involvement of an inspection body independent of the
manufacturer of shell boilers as defined in EN 12952-1.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

4 Guidance
4.1 General
The manufacturer ensures that this document, including inspection and testing activities, is fully applied.
If a CE marking is sought, it is a requirement of Directive 2014/68/EU that (in many cases) there is a
supplementary involvement of a responsible authority to ensure the requirements of Directive
2014/68/EU are met.
The kind and extent of responsible authority involvement in inspection and testing activities will depend
upon the conformity assessment procedure chosen by the manufacturer. For each appropriate
conformity assessment procedure the participation is described in this CEN technical report.
For the purpose of this document, a definition of Responsible Authorities is given in EN 12952-1:2022,
3.6.
The involvement of responsible authorities is recognized by this document as indicated below:
a) in connection with conformity assessment requirements;
b) arising from the complexity of the technical requirements.
4.2 Conformity assessment modules
Boilers are classified by category.
NOTE See the conformity assessment Table 5 of Directive 2014/68/EU Annex II.
Most likely, the categories III and IV apply to water tube boilers due to their size and operational
parameters in common industrial applications.
Therefore the conformity assessment modules B (production type) + D or B (design type) + F or G or H1
are applicable. The following key requirements are assigned to those modules:
A Made under the manufacturer’s own responsibility
A1 The manufacturer’s own responsibility but final assessment is monitored by the Notified
Body.
B The manufacturer establishes a EC Type Examination Certificate with the Notified Body.
B1 The manufacturer establishes a EC Design Examination Certificate with the Notified Body.
C1 Made to conform to a EC Type Examination Certificate with manufacture monitored by the
Notified Body.
D The manufacturer uses an approved Quality System and conforms to either a EC Design
Examination or EC Type Examination Certificate.
D1 The manufacturer uses an approved Quality System, and manufactures without the use of a
EC Design Examination or EC Type Examination Certificate.
E The manufacturer uses an approved Quality System and conforms to a EC Type Examination
Certificate.
E1 The manufacturer uses an approved Quality System, without a EC Type Examination
Certificate.
F Made to either a EC Type or Design Examination Certificate with each pressurized equipment
being examined by the Notified Body.
G The manufacturer selects the notified body. The Notified Body carries out the examinations
on each pressurized equipment.
H The manufacturer uses an approved Quality System for each pressurized equipment.
H1 The manufacturer uses an approved Quality System. The Notified Body issues a EC Design
Examination Certificate and takes part in the final assessment of the pressurized equipment.
4.3 Technical complexity
Where the technical requirements are complex and no clearly defined procedure is given in this
EN 12952, it is the convention within the boiler industry for the manufacturer to prepare procedures
based on his own experience proposing how the design/manufacture proceed. In such cases the
proposals are normally submitted to the RA for appraisal. Such appraisal will normally be completed at
the initial design stage, but it is recognized that similar proposals can be needed to introduce design
modifications and/or to accommodate concessions (deviations) during the manufacturing stage. These
latter proposals also form part of the design/type appraisal procedure.
5 Conformity assessment activities
The extent of RA involvement will depend upon the conformity assessment procedure adopted by the
manufacturer. The assumed involvement of the RA for each appropriate conformity assessment module,
is shown in Annex B for category IV steam boilers. For category III steam boilers appropriate modules
can be chosen. For the guidance of the manufacturer, examples for the following certificates are given in
Clause Annex B: Manufacturer's Declaration of Conformity, Responsible Authority's Certificate of
Conformity, EU-type examination certificate – production type, EU-type examination certificate – design
type, Responsi
