Foreword
This document (CR 12953-14:2002) has been prepared by Technical Committee CEN /TC 269, "Shell and water-
tube boilers" the secretariat of which is held by DIN.
The European Standard EN 12953 concerning shell boilers 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.

Part 4: Workmanship and construction of pressure parts of the boiler.

Part 5: Inspection during construction, documentation and marking of pressure parts of the boiler.

Part 6: Requirements for equipment for the boiler.

Part 7: Requirements for firing systems for liquid and gaseous fuels for the boiler.

Part 8: Requirements for safeguards against excessive pressure.

Part 9: Requirements for limiting devices of the boiler and accessories.

Part 10: Requirements for boiler feedwater and boiler water quality.

Part 11: Acceptance tests.

Part 12: Requirements for firing systems for solid fuels for the boiler.

Part 13: Operating instructions.
CR 12953-14: Guidelines for the involvement of an inspection body independent of the manufacturer.
Although these Parts can be obtained separately, it should be recognized that the Parts are inter-dependent. As
such, the design and manufacture of shell boilers requires the application of more than one Part in order for the
requirements of the standard to be satisfactorily fulfilled.

EN 12953-1, Shell boilers — Part 1: General.
EN 12953-5, Shell boilers — Part 5: Inspection during construction, documentation and marking of pressure parts
of the boiler.
3 Modules
3.1 General
Each shell boiler should be designed and manufactured under the surveillance of an inspection body (RA)
independent of the manufacturer. For the purposes of EN 12953, the inspection body is called a Responsible
Authority (RA) as defined in EN 12953-1. The extent of the inspections performed by the RA is dependent on the on
the particular module chosen by the manufacturer.
Whilst the majority of shell boilers manufactured to this European Standard fall under the modules G or H1, other
modules can be chosen by the manufacturer (see EN 12953-1:2002, clause B.2).
For the purpose of EN 12953, the general requirements of the Pressure Equipment Directive (PED) have been
specifically interpreted for both modules G or H1 as given in 3.2 and 3.3.
When the shell boiler is designed and manufactured under the requirements of the PED, then the documents in
clause 4 should be supplied to the purchaser.
3.2 Module G
The manufacturer should ensure and declare the shell boiler conforms to EN 12953, and if manufactured under the
requirements of the PED, the RA should affix the CE mark and produce a Declaration of Conformity (see Figure 1).
A RA should be involved in the design, manufacturing and inspection stages in accordance with Table 1. If
manufactured under the requirements of the PED, issue a Certificate of Conformity (see Figure 2) for the tests
undertaken, affix or cause to be affixed its (their) identification number(s) on the approved equipment.

This assessment is included in the formal assessment of the boiler manufacturer's quality system.

It is not intended that these inspection operations will be undertaken on a regular basis. The RA can decide which
operations it requires to inspect, and these may be reduced as experience is gained between the RA and the
manufacturer. These operations should be completed prior to the review of the Data Dossier.

The RA will decide on the number of radiographs it will examine.
d
The identification number of the RA who assesses the manufacturer's quality system and, if different, that of the
RA involved during the design, fabrication and final inspection stages of the boiler.
3.3 Module H1
The manufacturer should operate a full quality assurance system for the design, manufacture and inspection. This
system should be approved and subjected to regular surveillance by a RA.
During the design and construction of a specific shell boiler contract, the manufacturer should ensure and declare the
shell boiler conforms to EN 12953, and if manufactured under the requirements of the PED affix the CE mark and the
identification number of the RA responsible for the quality surveillance and produce a Declaration of Conformity (see
Figure 1).
A RA should approve the design. If manufactured under the requirements of the PED, the RA should produce a
Design Examination Certificate (see Figure 3).
A RA should be involved in the manufacturing and inspection stages in accordance with Table 1. If manufactured
under the requirements of the PED, the RA should affix or cause to be affixed its identification number on the
approved equipment, and issue a Test report (see Figure 4) for the inspection stages with which it has been involved.
The RA involved in the approval of the design, the manufacture and inspection of a specific shell boiler contract need
not necessarily by the same RA as that involved in the approval and surveillance of the manufacturer's quality system.
4 Documentation required under the Pressure Equipment Directive
4.1 General
If the boiler is manufactured and supplied under the requirements of the Pressure Equipment Directive, then the RA
is a Notified Body (NB) and the recommendations in 4.2 and 4.3 apply.
4.2 Documents to be prepared
The following documents should be prepared:
a) a Declaration of conformity (see Figure 1) by the manufacturer stating that the boiler has been designed,
constructed and tested in accordance with the requirements of the Pressure Equipment Directive.
b) a certificate of conformity for tests (see Figure 2) by a NB for Module G, if required;
c) a EC design examinati
