iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression techniques, has labored with leading industry physique the Fire Protection Association (FPA), to help it acquire UKAS accreditation for one of its fire-testing laboratory services – changing into the first and only test facility in the UK to hold this accreditation.
เพรสเชอร์เกจ -growing Hull-headquartered business, which has developed its own vary of high-pressure water-mist fire-suppression systems, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fire testing in Blockley, Gloucestershire, which is among the most comprehensive fire check and research operations within the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the assist of iMist’s experienced group.
The UKAS accreditation of the FPA’s BS 8458 Annex C hearth testing marks another important milestone within the growth of water-mist systems within the UK.
diaphragm seal , operations director of iMist, comments: ‘For over 75 years, the FPA has been on the forefront of fire security and we’re proud to have assisted them in achieving this respected third-party accreditation. It is an extra demonstration of the rising importance of high-pressure water-mist methods in tackling the present challenges going through the fire-suppression sector. Not only do they use significantly much less water than traditional sprinkler systems, they’re also simpler and sooner to put in and, thereby, more cost effective.’

As part of its ongoing R&D product testing programme, iMist has also undertaken a series of stay hearth testing at the FPA’s UKAS accredited laboratory, which has elevated the system’s purposes, demonstrating that in addition to being installed in the cavity above the ceiling, the iMist system pipework can safely and successfully be installed under a plasterboard ceiling.
For the stay fire checks, the iMist nozzle was fed by both flexible and solid pipework operating below a normal plasterboard ceiling. In every of the checks, the gas load was ignited and the warmth from the hearth caused the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fine water-mist particles at high stress for 30 minutes. During this time, the temperatures at predetermined heights within the test cell had been measured by thermocouples. At no point during any of the checks were any of the Annex C temperature limits breached and all the fires had been successfully suppressed.
Timothy Andrews, iMist enterprise growth director, added: ‘While fire system pipework is usually put in in the cavity above a ceiling, in some properties, significantly in older tower blocks, there are frequent issues across the possible break-up of asbestos hidden in ceiling materials. Our latest indicative exams present that the housing business can now explore one other much less disruptive and extremely effective option by putting in a water-mist system below the prevailing ceiling. Given the growing have to retrospectively fit fire-suppression systems so as to meet the newest regulatory necessities and convey older housing stock up to present requirements, that is great news for each landlords and developers.’
