iMist helps FPA laboratory acquire UKAS accreditation and undertakes testing into further system applications

iMist, one of the UK’s foremost suppliers of high-pressure water-mist fire-suppression methods, has labored with main industry body the Fire Protection Association (FPA), to assist it acquire UKAS accreditation for considered one of its fire-testing laboratory services – becoming the first and solely test facility in the UK to carry 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 amongst the most comprehensive hearth test and research operations within the UK. IMist offered the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the support of iMist’s skilled team.
The UKAS accreditation of the FPA’s BS 8458 Annex C fire testing marks another necessary milestone in the growth of water-mist systems in the UK.
Alex Pollard, operations director of iMist, comments: ‘For over seventy five years, the FPA has been on the forefront of fireside security and we’re proud to have assisted them in reaching this revered third-party accreditation. It is an extra demonstration of the rising significance of high-pressure water-mist systems in tackling the current challenges dealing with the fire-suppression sector. Not only do they use considerably less water than traditional sprinkler systems, they are also easier and faster to install and, thereby, more economical.’
As a half of its ongoing R&D product testing programme, iMist has additionally undertaken a collection of stay hearth testing on the FPA’s UKAS accredited laboratory, which has increased the system’s purposes, demonstrating that along with being put in within the cavity above the ceiling, the iMist system pipework can safely and successfully be put in below a plasterboard ceiling.
For the reside fire exams, the iMist nozzle was fed by both flexible and strong pipework working below a regular plasterboard ceiling. In each of the tests, the gasoline load was ignited and the heat from the fireplace caused the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fantastic water-mist particles at excessive pressure for 30 minutes. During this time, the temperatures at predetermined heights within the take a look at cell have been measured by thermocouples. At เกจวัดแรงดันถังออกซิเจน during any of the exams were any of the Annex C temperature limits breached and all the fires have been successfully suppressed.
Timothy Andrews, iMist enterprise improvement director, added: ‘While fireplace system pipework is normally put in within the cavity above a ceiling, in some properties, particularly in older tower blocks, there are frequent issues around the possible break-up of asbestos hidden in ceiling materials. Our latest indicative exams show that the housing industry can now explore one other much less disruptive and extremely efficient option by installing a water-mist system beneath the existing ceiling. Given the growing have to retrospectively fit fire-suppression techniques in order to meet the newest regulatory necessities and bring older housing inventory as much as present requirements, this is great information for both landlords and builders.’
