BS 845-2:1987

This standard BS 845-2:1987 Methods for assessing thermal performance of boilers for steam, hot water and high temperature heat transfer fluids. is classified in these ICS categories:

• 27.060.30 Boilers and heat exchangers

This Part of BS 845 describes a comprehensive procedure for conducting thermal performance tests on steam, hot water or high temperature heat transfer fluid boilers to give results within a tolerance of ± 2 percentage points¹⁾ and for presenting the results in tabular form. This Part makes use of both the direct and the indirect methods of test. Test results are based on either the gross or the net calorific value of the fuel.

This comprehensive procedure is suitable for all boilers, including those with multiple thermal flows to and from the boiler.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

A comprehensive test method, for assessing the thermal performance of any boiler, generally of output greater than 44 kW, including those with multiple thermal flows to and from the boiler and fired by solid, liquid or gaseous fuels.
