What is BS EN 12953-5 about?
BS EN 12953-5 is the fifth in a 14-part series on shell boilers. BS EN 12953-5 details inspection requirements so that the type of shell boiler covered is consistently safe.
BS EN 12953-5 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 are intended for land use for providing steam or hot water.
BS EN 12953 specifies requirements for inspection during and after construction, documentation and marking of shell boilers as defined in BS EN 12953-1:2012.
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 BS EN 12953-5, 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.
Who is BS EN 12953 for?
BS EN 12953 on shell boilers is applicable for industries that require steam or hot water such as process industries, hospitals, large buildings with heating systems and/or process steam. BS EN 12953 is also applicable where auxiliary steam is a start-up requirement for a larger plant (for example, power plant). BS EN 12953 is useful for:
- Boiler manufacturers
- Plant operators
- Plant maintenance personnel
- Inspection authorities
- Welders
Why should you use BS EN 12953?
Since shell boilers involve the use of hot water and steam, safety is of utmost importance. BS EN 12953 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. BS EN 12953 also helps manufacturers to comply with the European Union’s Pressure Equipment Directive (PED).
BS EN 12953 also specifies visual testing carried out by trained personnel in welding techniques to identify and interpret imperfections that might occur at the surface of the weld and heat-affected zone. If you use or manufacture shell boilers, then testing them will ensure the safety of your staff while they work.
