This Standard specifies design, construction, equipment, operational and water treatment requirements drawn up with a view to ensuring the operating safety of new stationary shell boiler plants. This Standard includes the requirements for the prevention of over-heating and inadmissible over-pressurisation.

It covers areas such as:

  1. the shell boiler including all pressure parts from the feed water inlet (including the inlet valve) to the steam and/or hot-water outlet (including the outlet valve). This includes economisers, superheaters and associated connecting pipes which are heated by flue gas and are not separated from the main system by intervening shut-off devices. Also included is any piping connecting the boiler to and including the first isolating valve;
  2. isolated economisers, superheaters and associated connecting pipes;
  3. expansion vessels and/or expansion tanks for plants for hot water production;
  4. thermal insulation and/or refractory and cladding;
  5. installations for heat supply and heating;
  6. installations for processing and feeding the fuel into the boiler;
  7. installations for the air supply of the boiler including the fans;
  8. installations for the feedwater supply of the boiler;
  9. all control and safety systems.

This Standard specifies requirements for both directly fired and electrically heated boilers including low pressure boilers (LPB, see 3.7) as well as for waste-heat 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 are intended for land use for providing steam or hot water. Where a particular boiler is a combination of shell and water-tube design then the water-tube standard series BS EN 12952 is used in addition to this standard.

It applies to the boiler proper, from the feed-water inlet connection to the steam outlet connection and to all other connections, including the valves and steam and water fittings. If welded ends are used, the requirements specified begin or end at the weld where flanges, if used, would have been fitted.

It applies to boilers having a capacity of greater than 2 l, a maximum allowable pressure greater than 0,5 bar and with a maximum design temperature in excess of 110°C.

The boiler plant comprises, besides the boiler proper, all pieces of equipment necessary for the intended mode of operation, for which requirements have been laid down in the different parts of this standard.

It does not apply to water-tube boilers, to boilers for railway locomotives, or to marine boilers. It also does not cover brickwork setting and insulation.

As with BS EN 12952, these Parts may be obtained separately but they are inter-dependent. As such, the design and manufacture of boilers requires the application of more than one Part in order for the requirements of the Standard to be fulfilled.
