iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression methods, has labored with leading industry physique the Fire Protection Association (FPA), to help it acquire UKAS accreditation for certainly one of its fire-testing laboratory amenities – changing into the first 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 vary of high-pressure water-mist fire-suppression techniques, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fireplace testing in Blockley, Gloucestershire, which is doubtless one of the most comprehensive hearth check and analysis operations in the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the support of iMist’s experienced staff.
The UKAS accreditation of the FPA’s BS 8458 Annex C fireplace testing marks another essential milestone in the improvement of water-mist systems in the UK.
Alex Pollard, operations director of iMist, feedback: ‘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 importance of high-pressure water-mist systems in tackling the current challenges facing the fire-suppression sector. Not only do they use considerably less water than conventional sprinkler techniques, they are additionally simpler and quicker to put in and, thereby, more economical.’

As part of its ongoing R&D product testing programme, iMist has also undertaken a series of live hearth testing on the FPA’s UKAS accredited laboratory, which has elevated the system’s applications, demonstrating that in addition to being installed within the cavity above the ceiling, the iMist system pipework can safely and successfully be installed under a plasterboard ceiling.
For the reside fireplace exams, the iMist nozzle was fed by each flexible and solid pipework operating beneath a standard plasterboard ceiling. In every of the tests, the gasoline load was ignited and the warmth from the fireplace brought on 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 half-hour. During this time, the temperatures at predetermined heights within the check cell were measured by thermocouples. At ไดอะแฟรม throughout any of the tests had been any of the Annex C temperature limits breached and all the fires were successfully suppressed.
Timothy Andrews, iMist business improvement director, added: ‘While hearth system pipework is normally installed in the cavity above a ceiling, in some properties, particularly in older tower blocks, there are frequent points across the attainable break-up of asbestos hidden in ceiling supplies. Our newest indicative tests show that the housing business can now discover one other much less disruptive and extremely efficient option by installing a water-mist system beneath the present ceiling. Given the rising must retrospectively match fire-suppression systems to have the ability to meet the newest regulatory requirements and bring older housing inventory up to present standards, that is great news for each landlords and builders.’
