What is BS EN 12953-5:2020 about?
This European standard is the fifth in a 14-part series on shell boilers. BS EN 12953-5:2020 details inspection requirements so that the type of shell boiler covered is consistently safe.
Who is BS EN 12953-5:2020 for?
Industries that require steam or hot water such as process industries, hospitals, large buildings with heating systems and/or process steam; also where auxiliary steam is a start-up requirement for a larger plant (e.g. power plant). The standard will be used by:
- Boiler manufacturers
- Plant operators
- Plant maintenance personnel
- Inspection authorities
Why should you use BS EN 12953-5:2020?
This European standard ensures 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. Its use will also help manufacturers comply with the European Union’s Pressure Equipment Directive (PED).
The standard specifies requirements for inspection during and after construction, documentation and marking of shell boilers as defined in BS EN 12953-1:2012.
It 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 boilers covered by BS EN 12953-5:2020 are intended for land use for providing steam or hot water.
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 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 BS EN 12953-7 and BS EN 12953-8).
NOTE 1: 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 PED.
NOTE 2: For other components, such as water tube walls, reference will be made to the BS EN 12952 series.
