iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression systems, has labored with main trade physique the Fire Protection Association (FPA), to assist it acquire UKAS accreditation for considered one of its fire-testing laboratory facilities – turning into the primary and only take a look at facility in the UK to carry this accreditation.
The fast-growing Hull-headquartered business, which has developed its own vary 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 one of the most complete fireplace check and analysis operations in the UK. IMist offered the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the assist of iMist’s skilled staff.
The UKAS accreditation of the FPA’s BS 8458 Annex C fireplace testing marks one other important milestone within the development of water-mist methods in the UK.
Alex Pollard, operations director of iMist, feedback: ‘For over seventy five years, the FPA has been at the forefront of fireplace safety and we’re proud to have assisted them in achieving this revered third-party accreditation. It is an extra demonstration of the growing significance of high-pressure water-mist systems in tackling the current challenges dealing with the fire-suppression sector. Not solely do they use considerably much less water than conventional sprinkler systems, they are also easier and quicker to put in and, thereby, less expensive.’
As a part of its ongoing R&D product testing programme, iMist has also undertaken a sequence of reside hearth testing at the FPA’s UKAS accredited laboratory, which has increased the system’s applications, demonstrating that in addition to being put in within the cavity above the ceiling, the iMist system pipework can safely and effectively be put in beneath a plasterboard ceiling.
For the live hearth tests, the iMist nozzle was fed by both versatile and solid pipework working under a standard plasterboard ceiling. In each of the tests, the fuel load was ignited and the heat from the hearth triggered the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the nice water-mist particles at excessive pressure for half-hour. During เครื่องมือวัดความดันคือ , the temperatures at predetermined heights within the take a look at cell were measured by thermocouples. At no point throughout any of the tests had been any of the Annex C temperature limits breached and all the fires have been efficiently suppressed.
Timothy Andrews, iMist business improvement director, added: ‘While fireplace system pipework is usually installed within the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent issues across the potential break-up of asbestos hidden in ceiling materials. Our newest indicative tests show that the housing trade can now discover another less disruptive and extremely effective option by installing a water-mist system below the present ceiling. Given the rising must retrospectively fit fire-suppression systems to find a way to meet the most recent regulatory necessities and convey older housing inventory as a lot as current standards, this is nice information for each landlords and builders.’
