“9 Evaluation of conformity

9.1 General

The compliance of a roomheater appliance with the requirements of this standard and with the stated values
shall be demonstrated by:

- initial type testing,
- factory production control by the manufacturer, including product assessment.

For the purposes of testing, appliances may be grouped into families, where it is considered that the selected
performance characteristic or characteristics, especially in respect of those detailed in Table 11 and Table 12,
is/are common to all appliances within that family.


9.2 Type testing

9.2.1 Initial type testing

Initial type testing shall be performed to demonstrate conformity to this standard. In the case of an appliance
already in production the appliance to be tested shall be chosen at random and be representative of general
production and the manufacturer shall provide a written declaration to this effect.

In the case of a prototype the appliance tested shall be a model representative of the intended future production
and the manufacturer shall provide a written declaration that this is the case. When the appliance goes into
production a dimensional and constructional check shall be undertaken on the production appliance to confirm
it is in agreement with the originally type tested prototype model. If the dimensions of the production appliance
diverge by more than 1 % of the dimension or ± 3 mm whichever is the lesser from that of the prototype in
relation to the firebox and/or combustion chamber and any other dimension considered to be critical to the
safety or performance of the appliance (especially in respect of the characteristics of Table 11 and Table 12)
then the production appliance itself shall be subjected to further type testing as detailed in 9.2.2.

Similarly, if there is a change to the construction materials used which will adversely alter the performance
characteristics of the appliance especially as regards its safety and/or the meeting of the performance
characteristics of Table 12 then the production appliance itself shall be subject to further type testing as detailed
in 9.2.2. This requirement regarding re-testing shall be applied if during the subsequent production or at the
start of a new production run such a change is made to dimensions and/or construction materials. To ensure
that this takes place there shall be a dimensional/constructional check on a current production appliance over
an ongoing period not exceeding 3 years to demonstrate conformity to type.

Where tests have been previously performed in accordance with the provisions of this standard (same product,
same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) then the
results of these tests shall be taken into account in assessing continuing conformity to type.

For a family or range of appliance it shall be permissible to test only selected appliances across the family or
range and to only verify selected constructional and performance characteristics on the others, subject to a
clear decision being made that the appliances are part of a family or range of appliances. For the initial type test
at least a sufficient number of the appliances shall be chosen from across the family or range so as to represent
7

---------------------- Page: 8 ----------------------

EN 13240:2001/A2:2004 (E)
adequately the family or range. The chosen appliances shall be subjected to complete testing to fully verify their
compliance with all of the constructional and performance characteristics in accordance with this standard. For
the other appliances in the family or range not chosen for complete testing it shall be permissible to only verify
selected constructional and/or performance characteristics to ensure their compliance with the requirements of
this standard and/or to ensure they will perform the same as the fully type tested appliances of the family or
range.

In selecting appliances for type testing from a product range based upon their nominal heat outputs as
representing such a family then appliances having the lowest and highest claimed nominal heat outputs shall be
tested together with sufficient appliances chosen from within the range that the ratio of nominal heat output
between the appliances does not exceed the ratio of 1,6:1.

Further, in deciding that the appliances belong to a family or range due account shall be taken of the
construction and performance characteristics of each appliance especially in respect of the list of characteristics
detailed in Table 11 and Table 12. The list of characteristics in Table 11 and Table 12 is not definitive and other
aspects may need to be considered in making this judgement. Where a range of appliances of the same
firebox and output have differing canopies or external cladding both in size and materials of construction (eg
where the hot surface would be likely to be closer to combustible surfaces or there is a change from a lower to
a higher conductivity or emissivity material) then at least one appliance shall be chosen which will be the worst
scenario case and will demonstrate the safety of the range as regards surface temperature and safety of
adjacent combustible materials.

Where the manufacturer claims conformity to the standard for a family of appliances on a number of different
fuel types a selection of tests shall be made which demonstrates the conformity of the family in respect of the
safety (clause 5) and performance (clause 6) on these fuels on the appliances especially to the list of
characteristics detailed in Table 11 and Table 12.

The parameters, characteristics examined and considerations taken into acount in making the decisions in
relation to the family or range of appliances shall be recorded and a copy included in the production
documentation for each appliance of the family or range (see 4.1).

9.2.2 Further type testing

Whenever a change occurs in either the appliance design, the raw material, the supplier of the components, or
the production process, which would significantly alter the performance characteristics of the appliance
especially in respect of one or more of the list of characteristics detailed in Table 11 and Table 12, the type tests
shall be repeated for the appropriate characteristic(s).

It shall be permissible for this further type testing to verify only selected constructional and/or performance
characteristics to ensure their compliance with the requirements of this standard and/or with the fully type tested
appliances of the family or range.

For a family or range of appliance it shall be permissible to test only selected appliances across the family or
range and to verify only selected constructional and performance characteristics on the others, subject to a
clear decision being made that the appliances are part of a family or range of appliances.

In deciding the constructional and/or performance characteristics to be verified or the appliances to be tested (in
the case of a family or range of appliances) due account shall be taken of the performance characteristics
detailed in Table 12 together with the list of characteristics detailed in Table 11. The list of characteristics in
Table 11 and Table 12 is not definitive and other aspects may need to be considered in making this judgement.

Where tests have been previously performed in accordance with the provisions of this standard then these test
results shall also be taken into account in making the decision.

The parameters and characteristics considered in making either the decisions in relation to the constructional
and/or performance characteristics to be verified or the appliances to be tested (in the case of a family or range
of appliances) shall be recorded and a copy included in the production documentation for each appliance (see
4.1).

The trihedron shall consist of a hearth, a side wall and a rear wall each at right angles one to the other. For
those appliances where it is necessary to measure the temperature of the ceiling then a ceiling shall also be
fitted in accordance with the manufacturer’s installation instructions.

NOTE 1 Examples of the general arrangement and construction of the trihedron are given in Figures A.3 and A.4. An
example of an installation with walls and ceiling is given in Figure A.14.”

The trihedron hearth and walls and/or ceiling, if required, shall be constructed as illustrated in Figure A.5 or
