Water Mist Testing

On the 23rd March 2016 our custom built water mist system undertook independent third party rigorous inspection by Exova Warrington Fire, a UKAS accredited laboratory, achieving the required testing and standards criteria.

Testing is done on set criteria and also ensures systems are tested to cover fire compartments of up to 80m2 which when achieved, allows water mist system to be used on domestic and residential projects across the UK. Full transparency of test reports and certificates are available upon request for potential clients.

Exova Warrington Fire carried out two sets of performance fire tests which are detailed in the standards listed below.

BS 8458

Objective: To demonstrate the capability of a water mist system to control a fire when tested in accordance with BS 8458:2015: Annex C.

Conclusion: The water mist system suppressed the fuel packages and met all the criteria specified in Clause 6.1 (a), (b) & (c) of BS 8458:2015 for domestic and residential purposes at a maximum of 80m².

BS 9252

Objective: To demonstrate the capability of a water mist system to control a fire utilising the principles of the test procedure defined in BS 9252:2011: Annex S.

Conclusion: Where the thermocouples were positioned at 1.6m above the floor, the temperatures did not exceed 55°C for any 120 second interval.

The IPH Water Mist System is a viable alternative to traditional sprinkler systems and our designs are submitted in conjunction with the following standards as applicable:

BS 8458 – BS 9251 – BS 9252 – BS 7671

(other standards may apply)

*It should be noted that BS:9252 is a sprinkler standard not a water mist standard, therefore it is not possible for the iCO nozzle to comply to the flow requirement (or design density as it is commonly known) of the tests. Sprinklers and water mist are fundamentally different in this regard as it was determined that Water Mist Systems use less water at a higher pressure to create smaller droplets that control the fire more effectively.

**To verify the performance of our nozzle against this standard the test room, fire load and pass-fail criteria were exactly as prescribed in the standard. The only difference was the flow of water from our nozzle which was considerably less than a sprinkler system.

Validity

The specification and interpretation of fire test methods are the subject of ongoing development and refinement. Changes in associated legislation may also occur. For these reasons it is recommended the relevance of test reports over 5 years old should be considered by the user.

There are many alternative or innovative fire suppression systems available.

Where these are used it is necessary to ensure that such systems have been designed and tested for use in domestic buildings and are fit for their intended purpose.

*** We demonstrate that our systems have been designed and tested for use in domestic buildings and are fit for their intended purpose by our system performance fire tests carried out to BS8458 (Fixed fire protection systems – Residential and domestic water mist systems – Code of practice for design and installation) and BS9252:2011 (Components for residential sprinkler systems – Specification and test methods for residential sprinklers) carried out by a UKAS accredited laboratory, Exova Warrington Fire.

Note: There are no traditional sprinklers available on the market that have been successfully tested to BS9252. The sprinkler industry instead of adhering to ‘British Standard’ use an American UL test.

Our water mist suppression system can detect, suppress and control a fire at an early stage of development and activate an alarm. Operation of the system rapidly reduces the rate of production of heat and smoke, allowing more time for the occupants to escape to safety or be rescued.

It is essential that automatic fire suppression systems are properly designed, installed and maintained.

Increased Fire Safety Measures

Following recent Government Legislation change (May 2020), fire suppression systems are now regarded as a mandatory requirement for a wider range of residential and domestic properties and apartment blocks that marks the greatest change to building safety systems in a generation!

What are the 2 parts of PAS 79 2020

PAS 79, which was last revised in 2012, provided generic fire risk assessment guidance. However, the housing sector wanted more housing-specific recommendations to be developed. It was therefore decided to revise PAS 79, updating the existing PAS and renaming it as Part 1, and introducing a new, housing-specific, Part 2.
