iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression techniques, has labored with main business body the Fire Protection Association (FPA), to help it achieve UKAS accreditation for certainly one of its fire-testing laboratory facilities – turning into the first and solely test facility within the UK to carry this accreditation.
The fast-growing Hull-headquartered enterprise, 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 fireplace testing in Blockley, Gloucestershire, which is certainly one of the most complete fire test and research operations in the UK. IMist provided the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the support of iMist’s skilled group.
The UKAS accreditation of the FPA’s BS 8458 Annex C hearth testing marks one other essential milestone within the improvement of water-mist techniques within the UK.
Alex Pollard, operations director of iMist, feedback: ‘For over 75 years, the FPA has been on the forefront of fireside security and we’re proud to have assisted them in attaining this respected third-party accreditation. It is an extra demonstration of the growing importance of high-pressure water-mist methods in tackling the present challenges going through the fire-suppression sector. Not solely do they use significantly less water than conventional sprinkler techniques, they’re also simpler and faster to put in and, thereby, more price effective.’

As เพรสเชอร์เกจ of its ongoing R&D product testing programme, iMist has additionally undertaken a sequence of live fire testing at the FPA’s UKAS accredited laboratory, which has increased the system’s functions, demonstrating that along with being put in within the cavity above the ceiling, the iMist system pipework can safely and effectively be installed under a plasterboard ceiling.
For ไดอะแฟรม ซีล , the iMist nozzle was fed by both flexible and solid pipework running beneath a normal plasterboard ceiling. In each of the exams, the gasoline 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 stress for 30 minutes. During this time, the temperatures at predetermined heights within the take a look at cell have been measured by thermocouples. At no level throughout any of the exams had been any of the Annex C temperature limits breached and all the fires had been efficiently suppressed.
Timothy Andrews, iMist enterprise growth director, added: ‘While fireplace system pipework is normally installed within the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent issues around the potential break-up of asbestos hidden in ceiling supplies. Our latest indicative tests present that the housing trade can now explore another less disruptive and highly effective option by installing a water-mist system beneath the existing ceiling. Given the growing have to retrospectively match fire-suppression systems to find a way to meet the most recent regulatory requirements and convey older housing inventory as much as current standards, that is great news for each landlords and developers.’
