Short introduction.

My first presentation held about watermist was done in Norway back in 2006 while participating in a theme day about mobile life-safety control and

suppression systems arranged by Vestfold Interkommunale Brannvesen.

2014-2017 May 25 - Aug 17, 2017 2017-18 2018-19

Estimate

• used in more than one European country• more than one approval, based on such test procedure, by different manufacturers• time-proven (period of at least 2 years since first approval)• no proven concerns about failure• it shall not be in contradiction to the main body of the standard

The “2017” format of CEN 14972 EN 14972, Fixed firefighting systems — Water mist systems, consists of the following parts:

— Part 1: Design, installation, inspection and maintenance;

— Part 2: Test protocol for shopping areas for automatic nozzle systems;

— Part 3: Test protocol for office, school class rooms and hotel for automatic nozzle systems ;

— Part 4: Test protocol for non-storage occupancies for automatic nozzle systems;

— Part 5: Test protocol for car garages for automatic nozzle systems;

— Part 6: Test protocol for false floors and false ceilings for automatic nozzle systems ;

— Part 7: Test protocol for commercial low hazard occupancies for automatic nozzle systems ;

— Part 8: Test protocol for machinery in enclosures exceeding 260 m3 for open nozzle systems;

— Part 9: Test protocol for machinery in enclosures not exceeding 260 m3 for open nozzle systems;

— Part 10: Test protocol for atrium protection with sidewall nozzles for open nozzle systems ;

— Part 11: Test protocol for cable tunnels for open nozzle systems;

— Part 12: Test protocol for commercial deep fat cooking fryers for open nozzle systems ;

— Part 13: Test protocol for wet benches and other similar processing equipment for open nozzle systems;

— Part 14: Test protocol for combustion turbines in enclosures exceeding 260 m³ for open nozzle systems;

— Part 15: Test protocol for combustion turbines in enclosures not exceeding 260 m³ for open nozzle systems;

— Part 16: Test protocol for industrial oil cookers for open nozzle systems.

Same quality level as sprinklers. Main difference is each system design specifics is found through successful testing (to part 2-X). Commonly used components references to EN12259+12845 (low pressure ) and EN12094 (high pressure). Specific WM component standards will be sent out as TS and later EN (>2018-19).

- Part 17: Test protocol for residential and domestic areas for automatic nozzle systems.

Sufficient system documentation

Successful testing conducted in ISO 17025 accredited test lab to a fire test method found in CEN/EN 14972 part 2-X + component test method for nozzles found in CEN/EN 14972 part 1.

Manufacturer makes DIOM manual based on results found in tests including all system specific details.

3. party to witness fire tests / approve test report, and approve DIOM manual.

OK documentation:Certificate

Product + datasheet sent to fire and component test lab.

OK documentation:Witness letter + fire-and component test report

CEN/TS14972 in a real project

All information to work with an appropriate watermist solution can be found in manufacturers “verified” DIOM manual + CEN/EN 14972 part 1.

Installer/Consultant define the application and applications specific details such as ceiling heights, room sizes, etc.

The Installer/Consultant looks into CEN/EN 14972 part 1 and verifies if there is a test method scope that match the application and the application specific details. If yes, then the installer can find suppliers that offer products 3. party verified to the specific test method (CEN/EN 14972 part 2-X) and chose the one that suits them best.

Local AHJ checks manufacturers documentation + that general requirements from CEN/EN 14972 part 1 is fulfilledSuccessful watermist project

How to work with WM until 14972 becomes EN?

Sweden: “SBF 503-1” (Available from end 2017).

Denmark: “DBI 254-1/2” (Available).Norway: “FG-950:3” (Available).

Follow the CEN/TS 14972:2011 version or national guidelines / standards until May 25th 2017. Thereafter follow the prEN14972 part 1-X or the national guidelines / standards until the EN 14972 is released (hopefully in year 2018-19). Below are examples of nations guidelines / standards:

3. Updates on the “FG-950:3 - veiledning for Vanntåkesystemer”

FG-950:3 updateUtgave 3 av vanntåke veiledningen utgis med gyldighet fra 1.12.2016.

Veiledningen har gjennomgått en omfattende revisjon (AP: rev 2 from 2009) hvor en bred sammensatt gruppe fra bransjen, forsikring og myndigheter har deltatt.

Det er viktig å merke seg at en veiledning ikke er et regelverk.

Hensikten er å beskrive anbefalinger, henvisninger til standarder og angi føringer i forhold til realisering av et prosjekt

Reference to prEN 14972 part 1 + DIOM Reference to CEN prEN14972, NFPA 750, VdS 3188 and BS 8489+BS8458+ certain additional requirements is set in FG-950, chapter 9 and 10.

In any case minimum same QC level as defined in EN12845 (INSTA 900-1 for domestic and residential systems).

Commissioning and Maintenance requirements.

EN 12845 / EN15004-1 where relevant + DIOM

FG-950: - Is a guideline.- Recognizes mainly system approvals for all components in the system.- Minimum QC level referenced to EN12845 (INSTA900 for residential and domestic

projects), but with some additional requirements for watermist compared to sprinklers.

prEN14972:- Is a standard.- Recognizes successful testing in ISO 17025 accredited labs to its own test procedures

(prEN14972 part 2-X)- Minimum QC level referenced to EN12259+EN12845 for low pressure systems and

EN14847 + EN12094 for high pressure systems.

Comparison summery

4. The future of watermist

Watermist “growth” problems▪ Fights between manufacturers instead of “working together” pushing the technology.

▪ Fights between the watermist community and the sprinkler community.

▪ To many different standards, codes, guidelines covering the same areas (confusion = > easier to do what has always been done).

▪ The watermist sales method (systems vs components => mistrust and high costs).

▪ Investment protection due to high approval costs (very little transparency => very little knowledge).
