GLOSSARY
BIID
The British Institute of Interior Design is a professional organisation for commercial and residential interior designers in Britain.
BSP
British Standard Piping.
Btu/hr
British Thermal Unit per hour is the standard measurement used to state the amount of outputof any heat generating device.
CETIAT tested
A leading independent French laboratory which conducts testing and assessments.
CIBSE
The Chartered Institution of Building Services Engineers is the prime source of expertise in the Building Services industry.
∆t
Refers to the difference in temperature between the water circulating in the central heating system and that
of the ambient temperature. It is important to use the correct ∆t when selecting your radiators, as the same
radiator will have different outputs at different water temperatures.
∆t50
∆t50 is the UK standard, however Stelrad also quote at lower levels for lower water temperature systems.
EN 442 is the European standard which defines the manufacturing standards for radiators and convectors which
operate at temperatures of less than 120°C. The standard defines the type of steel which must be used, the type
of pressure testing which must be carried out and the accuracy of the heat outputs quoted in the literature.
Heat loss
Is the amount of heat a room loses, it is therefore an important calculation when determining what size
radiator is required to heat a room to the correct level.
Is the UK's independent professional customer service body.
