This Part of this European Standard applies to atmospheric fluidized-bed and grate firing systems of steam boilers and hot water generators. These systems commence at the fuel bunkers and end at the ash extraction plant. For combination of various firing systems, the individual requirements of each system apply, especially those included in EN 12952-8 and EN 12952-9.
If several fuels are burnt simultaneously or if a fuel quality varies considerably (e.g. moisture content), additional safety measures may be necessary, especially with respect to limitation of the fuel flow into the firing system and ensuring proper air supply to the individual fuels.
Pressurized firing systems may require enhanced safety measures, which are not given in this European Standard.

The HRC contains the heat exchangers and all necessary features and auxiliary devices for the exchange of sensible heat and (if available) air humidity between exhaust air and supply air. The HRC will be installed in casings or ducts. If fans are part of the test unit, the effect of the fan power on the measured values will be corrected.
This document specifies procedures and input criteria required for tests to determine the performance of a HRC at one or several test conditions, each of them with continuous and stationary air flows, air temperatures and humidities at both inlet sides. Three different test types are covered:

— Test type B, Laboratory testing of HRC installed in non-residential ventilation units in design configuration;
— Test type C, on-site (field) testing of HRC in non-residential ventilation units (C1) or a HRC sections (C2) in operation configuration.
This document is applicable to recuperators, regenerators, and HRC with intermediary heat transfer medium.
This document prescribes test methods for determining:
1) the temperature and humidity efficiency,
2) the pressure drop of exhaust air and supply air sides,
3) possible internal leakages; exhaust air transfer ratio (EATR) and outdoor air correction factor (OACF),
4) external leakages and
5) auxiliary energy used for the operation of the HRC.
HRC using heat pumps are not covered by this document.

This European Standard specifies, the requirements and test methods concerning, in particular the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners and are hereafter referred to as boilers.
Where the word boiler is used, this is to be read as the boiler including its connecting ducts, ducts and terminals, if any.
This European Standard covers gas-fired central heating boilers type B11, B11BS, B12, B12BS, B13, B13BS according to the classification in CEN/TR 1749:2009:
a) that have a nominal heat input (on the basis of net calorific value) not exceeding 70 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437;
c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation;
d) where the maximum operating pressure in the water circuit does not exceed 6 bar;
e) which are declared in the technical instructions to be either a low temperature boiler or a standard boiler. If no declaration is given the boiler is to be considered a standard boiler;
f) which are intended to be installed either indoors or in a partially protected place;
g) which are either not intended to produce hot water, or are intended to produce hot water either by the instantaneous or storage principle, the whole being marketed as a single unit.
h) which are designed for either sealed water systems or for open water systems.
This European Standard is to be used in conjunction with the General Requirements Standard EN 15502 1.
For applications within the scope of the PED further requirements may be necessary (e.g. situations where the maximum allowable temperature exceeds 110 °C, or where volume times maximum allowable pressure is over 50 bar x litres).
This standard provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard, the risk associated with this alternative construction shall be assessed.
An example of an assessment methodology, based upon risk assessment and which covers the essential requirements of the Gas Appliance Directive, is given in Clause 11.
This standard does not cover all the requirements for:
i) appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex DD of EN 15502 2 1:2012);

1.1 General
This European Standard applies to shell boilers with volumes in excess of 2 litres for the generation of steam and/or hot water at a maximum allowable pressure greater than 0,5 bar and with a temperature in excess of
110 °C.
The purpose of this European Standard is to ensure that the hazards associated with the operation of shell boilers are reduced to a minimum and that adequate protection is provided to contain the hazards that still prevail when the shell boiler is put into service. This protection will be achieved by the proper application of the design, manufacturing, testing and inspection methods and techniques incorporated in the various parts of this European Standard. Where appropriate, adequate warning of residual hazards and the potential for misuse are given in the training and operating instructions and local to the equipment concerned (see EN 12953-7 and EN 12953-8).
It is the manufacturer's responsibility, in addition to complying with the requirements of this standard, to take into consideration special measures which could be necessary in order to achieve by manufacturing the required level of safety in accordance with the EU Directive 97/23/EC (PED).
NOTE 1 Further requirements relating to operating instructions in prEN 12953-13 and to hazard analysis in
CEN/TS 764-6 should be taken into consideration.
This European Standard specifies requirements for both directly fired and electrically heated boilers including Low Pressure Boilers (LPB, see 3.6) as well as for heat recovery boilers with a gas-side pressure not exceeding 0,5 bar of cylindrical design, constructed from carbon or carbon manganese steels by fusion welding and a design pressure not exceeding 40 bar. The boilers covered by this European Standard are intended for land use for providing steam or hot water (typical examples are shown in Figures 1 to 6).
For Low Pressure Boilers (LPB) less stringent requirements concerning design and calculation are acceptable. Details are defined in the respective clauses.
NOTE 2 For boilers operating at a pressure on the gas-side greater than 0,5 bar the rules of this standard equally apply. However, it is generally considered that additional design analysis, inspection and testing may be necessary.
Where a particular boiler is a combination of shell and water-tube design then the water-tube standard series EN 12952 is used in addition to this European Standard. One such example of this combination is shown in Figure 3.
This European Standard applies to the generator, from the feed-water or water inlet connection to the steam or water outlet connection and to all other connections, including the valves and steam and water fittings. If welded ends are used, the requirements specified herein begin or end at the weld where flanges, if used, would have been fitted.
1.2 Exclusions
This European standard does not apply to the following types of boilers and equipments:
a) water-tube boilers;
b) non stationary boilers, e.g. locomotive boilers;
c) thermal oil boilers;
d) boilers where the main pressure housing is made of cast material.
e) pumps, gaskets, etc.
f) brickwork setting and insulation, etc.
NOTE Stainless steel boilers are covered by EN 14222.

This European Standard identifies the requirements for the manufacturer to provide operating instructions for pressure equipment supplied in accordance with EN 12953-1 when placed on the market.
NOTE Where the equipment or assembly will reach the final user in a Member State which requires translation of operating instructions, manufacturers should be aware of this requirement.
