Currently, there are no fire tests carried out on sprinklers in Europe. The only fire testing of standard sprinklers is the ISO 6182-1 wood crib fire test used mainly in the US.

The Actual Delivered Density (ADD) equipment is a low running-cost apparatus specifically developed to fire test ESFR sprinklers. This first LPC ADD research project set out to extend this use by developing a methodology for using the ADD apparatus for testing spray and conventional sprinklers with k-factors of 80 and 115.
This project established a methodology that yielded similar results to the established wood crib fire test (found to be prohibitively expensive in Europe) used for evaluating standard K80 and K115 sprinklers. In this way the first steps were taken to developing a low running-cost alternative for fire testing standard sprinklers.

It is expected that the results and findings from the subsequent research carried out by LPC and FRS will be made available in the coming months.


This work was managed and carried out on behalf of the Association of British Insurers (ABI) who wholly funded the work.
