iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression methods, has labored with main trade physique the Fire Protection Association (FPA), to assist it achieve UKAS accreditation for one of its fire-testing laboratory facilities – turning into the primary and solely take a look at facility in the UK to carry this accreditation.
The fast-growing Hull-headquartered enterprise, which has developed its personal range of high-pressure water-mist fire-suppression systems, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C hearth testing in Blockley, Gloucestershire, which is likely one of the most comprehensive fireplace test and analysis operations within the UK. IMist provided the FPA with its proprietary pumps, pipework, hoses, clips and nozzles as properly as the help of iMist’s skilled group.
The UKAS accreditation of the FPA’s BS 8458 Annex C hearth testing marks another essential milestone in the growth of water-mist techniques in the UK.
Alex Pollard, operations director of iMist, comments: ‘For over 75 years, the FPA has been at the forefront of fireplace safety and we’re proud to have assisted them in reaching this respected third-party accreditation. It is an additional demonstration of the growing significance of high-pressure water-mist methods in tackling the present challenges going through the fire-suppression sector. เกจวัดแรงดันลม do they use considerably much less water than traditional sprinkler methods, they are additionally simpler and sooner to install and, thereby, more cost effective.’
As part of its ongoing R&D product testing programme, iMist has also undertaken a series of live fire testing at the FPA’s UKAS accredited laboratory, which has increased the system’s functions, demonstrating that in addition to being installed in the cavity above the ceiling, the iMist system pipework can safely and effectively be installed under a plasterboard ceiling.
For the reside hearth checks, the iMist nozzle was fed by each flexible and solid pipework operating under a normal plasterboard ceiling. In every of the checks, the gas load was ignited and the warmth from the fire brought on the bulb within the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fine water-mist particles at high stress for half-hour. During this time, the temperatures at predetermined heights within the check cell were measured by thermocouples. At no point throughout any of the checks had been any of the Annex C temperature limits breached and all the fires were successfully suppressed.
Timothy Andrews, iMist enterprise improvement director, added: ‘While fire system pipework is often put in in the cavity above a ceiling, in some properties, particularly in older tower blocks, there are frequent issues across the potential break-up of asbestos hidden in ceiling supplies. Our newest indicative exams present that the housing industry can now explore another less disruptive and extremely efficient possibility by putting in a water-mist system below the present ceiling. Given the rising have to retrospectively fit fire-suppression techniques in order to meet the newest regulatory requirements and produce older housing inventory as a lot as present requirements, this is nice news for both landlords and developers.’
