Water-tube boilers

BSI British Standards published all parts of the BS EN 12952 series. You may obtain all parts of BS EN 12952 separately but they are inter-dependent. As such, the design and manufacture of water-tube boilers requires the application of more than one part in order for the requirements of the standard to be fulfilled.

Key standards:

BS EN 12952-1:2001
Water-tube boilers and auxiliary installations.  General

BS EN 12952-1:2001 applies to water-tube boilers with volumes in excess of 2 litres for the generation of steam and/or hot water at an allowable pressure greater than 0,5 bar and with a temperature in excess of 110 °C as well as auxiliary installations (other plant equipment).

The purpose of this European Standard is to ensure that the hazards associated with the operation of water-tube boilers are reduced to a minimum and that adequate protection is provided to contain the hazards that still prevail when the water-tube 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 prEN 12952-8, prEN 12952-9 and prEN 12952-16).
