iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression methods, has labored with main business physique the Fire Protection Association (FPA), to help it achieve UKAS accreditation for considered one of its fire-testing laboratory facilities – turning into the primary and solely check facility within the UK to hold this accreditation.
The fast-growing Hull-headquartered enterprise, which has developed its personal 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 amongst the most comprehensive fireplace check and research operations within the UK. IMist provided 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 hearth testing marks one other important milestone within the improvement of water-mist systems in the UK.
Alex Pollard, operations director of iMist, comments: ‘For over 75 years, the FPA has been at the forefront of fire security and we’re proud to have assisted them in attaining this respected third-party accreditation. It is a further demonstration of the growing significance of high-pressure water-mist systems in tackling the current challenges going through the fire-suppression sector. Not only do they use considerably less water than traditional sprinkler systems, they’re additionally simpler and sooner to put in and, thereby, less expensive.’
As a half of its ongoing R&D product testing programme, iMist has additionally undertaken a series of stay hearth testing at the FPA’s UKAS accredited laboratory, which has elevated the system’s functions, demonstrating that along with being installed in the cavity above the ceiling, the iMist system pipework can safely and effectively be installed under a plasterboard ceiling.
For เครื่องมือที่ใช้ในการวัดความดัน , the iMist nozzle was fed by both versatile and solid pipework operating beneath a normal plasterboard ceiling. In every of the checks, the gas load was ignited and the heat from the hearth brought on the bulb within 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 this time, the temperatures at predetermined heights within the take a look at cell have been measured by thermocouples. At no level during any of the exams have been any of the Annex C temperature limits breached and the entire fires were successfully suppressed.
Timothy Andrews, iMist enterprise improvement director, added: ‘While fire system pipework is often put in within the cavity above a ceiling, in some properties, significantly in older tower blocks, there are frequent points around the possible break-up of asbestos hidden in ceiling materials. Our latest indicative tests present that the housing industry can now discover another much less disruptive and highly efficient possibility by putting in a water-mist system below the prevailing ceiling. Given the rising must retrospectively fit fire-suppression methods so as to meet the most recent regulatory requirements and bring older housing inventory as a lot as current requirements, this is nice news for each landlords and builders.’
