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

iMist, one of the UK’s foremost suppliers of high-pressure water-mist fire-suppression techniques, has worked with main business body the Fire Protection Association (FPA), to assist it achieve UKAS accreditation for one of its fire-testing laboratory facilities – becoming the primary and solely test facility within 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 systems, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C hearth testing in Blockley, Gloucestershire, which is one of the most complete fireplace 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 experienced team.
The UKAS accreditation of the FPA’s BS 8458 Annex C fire testing marks one other essential milestone in the growth of water-mist techniques in the UK.
Alex Pollard, operations director of iMist, comments: ‘For over 75 years, the FPA has been on the forefront of fireplace security and we’re proud to have assisted them in achieving this respected third-party accreditation. It is an additional demonstration of the rising significance of high-pressure water-mist techniques in tackling the present challenges dealing with the fire-suppression sector. Not only do they use considerably much less water than conventional sprinkler systems, they’re also simpler and faster to put in and, thereby, more economical.’

As a half of its ongoing R&D product testing programme, iMist has also undertaken a collection of reside fire testing on the FPA’s UKAS accredited laboratory, which has elevated the system’s applications, demonstrating that along with being put in within the cavity above the ceiling, the iMist system pipework can safely and effectively be put in under a plasterboard ceiling.
For the reside hearth tests, the iMist nozzle was fed by each versatile and stable pipework operating under a normal plasterboard ceiling. In every of the exams, the gas 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 fine water-mist particles at high pressure for 30 minutes. During this time, the temperatures at predetermined heights within the test cell had been measured by thermocouples. At no point during any of the tests had been any of the Annex C temperature limits breached and all the fires had been efficiently suppressed.
Timothy Andrews, iMist business development director, added: ‘While fire system pipework is usually put in in the cavity above a ceiling, in some properties, significantly in older tower blocks, there are frequent points across the attainable break-up of asbestos hidden in ceiling materials. เครื่องมือที่ใช้วัดความดันโลหิต show that the housing industry can now explore one other less disruptive and extremely efficient choice by putting in a water-mist system beneath the present ceiling. Given the growing need to retrospectively fit fire-suppression methods in order to meet the newest regulatory requirements and convey older housing inventory as much as present standards, this is great information for both landlords and builders.’
