iMist helps FPA laboratory achieve UKAS accreditation and undertakes testing into additional system functions

iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression methods, has labored with leading trade body the Fire Protection Association (FPA), to assist it achieve UKAS accreditation for one of its fire-testing laboratory services – changing into the primary and solely take a look at facility in the UK to hold this accreditation.
The fast-growing Hull-headquartered business, which has developed its own range of high-pressure water-mist fire-suppression methods, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fireplace testing in Blockley, Gloucestershire, which is doubtless certainly one of the most complete fire test and analysis operations within the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles as well as the help of iMist’s skilled staff.
The UKAS accreditation of the FPA’s BS 8458 Annex C fire testing marks one other essential milestone within the improvement of water-mist methods within the UK.

It is a further demonstration of the rising importance of high-pressure water-mist methods in tackling the current challenges going through the fire-suppression sector. Not solely do they use considerably less water than conventional sprinkler systems, they are additionally easier and quicker to put in and, thereby, more economical.’
As a part of its ongoing R&D product testing programme, iMist has also undertaken a series of reside fire testing on the FPA’s UKAS accredited laboratory, which has elevated the system’s purposes, demonstrating that along with being put in within the cavity above the ceiling, the iMist system pipework can safely and effectively be installed below a plasterboard ceiling.
For the stay fireplace tests, the iMist nozzle was fed by each flexible and solid pipework operating below a regular plasterboard ceiling. In each of the tests, the gasoline load was ignited and the warmth from the fireplace triggered the bulb within the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the nice water-mist particles at excessive stress for 30 minutes. During this time, the temperatures at predetermined heights within the check cell were measured by thermocouples. At no level during any of the tests have been any of the Annex C temperature limits breached and all of the fires were efficiently suppressed.
Timothy Andrews, iMist enterprise improvement director, added: ‘While hearth system pipework is usually put in in the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent issues around the potential break-up of asbestos hidden in ceiling materials. Our latest indicative exams present that the housing trade can now discover one other less disruptive and extremely effective choice by putting in a water-mist system below the present ceiling. Given Final growing have to retrospectively match fire-suppression methods so as to meet the most recent regulatory requirements and bring older housing inventory as a lot as present requirements, that is nice information for each landlords and builders.’
