R107

First fire suppression system approved in accordance with R107

Fogmaker approved in accordance with latest international standard for fire suppression systems in buses

Fogmaker became the first manufacturer to implement the official tests with successful results in October 2016. Fogmaker has also made the first fire suppression system available that has the type approval –                                                                             UNECE Regulation No.107 Cert. No. 06001 (2017-01-18).

Fire testing procedure follows four tests from SP method 4912, see results below:

*Test was performed with the suppression system container cooled to -30°C

Specifics for a R107-approved Fogmaker system*:

*Depending on the risk assessment for each specific engine, upscaling of extinguishant volume and number of nozzles will occur – the data below is the minimum requirement for the stated engine compartment gross volume.

– Gross volume “engine compartment”: 4 m³
– Extinguishant volume: 6.1 litres
– Number of spray nozzles: 11 pcs
– Type of nozzle: “Hollow cone nozzle” 1.2 l/min
– Distance most remote nozzle: 8 m

 

“Up and down” scaling (Sx ) depending on volume of the engine compartment:

Minimum volume of extinguishant is equal to:

  • If your engine compartment (x) > 4 m³ :   Sx = ([0,1 * X] + 0,6 ) * 6,1
  • If your engine compartment (x) < 4 m³ :   Sx = ([0,15 * X] + 0,4 ) * 6,1

Minimum number of nozzles is equal to:

  • If your engine compartment (x) > 4 m³ :   Sx = ([0,1 * X] + 0,6 ) * 11
  • If your engine compartment (x) < 4 m³ :   Sx = ([0,15 * X] + 0,4 ) * 11

For example, your engine compartment is 3 m³ then your minimum volume of extinguishant is =
=  ([0,15 * 3] + 0,4 ) * 6,1= 5.19 litres.

The minimum quantity of nozzles for that system is =
= ([0,15 * 3] + 0,4 ) * 11 = 9 nozzles.

 

More information about UNECE Regulation 107:

    • Legislation towards improved fire safety in buses and coaches in Europe (47 contracting parties applying)
    • Fixed installed FSS (Fire suppression system) will be a part of the bus manufacture´s vehicle approval
    • The requirement of installation of FSS applies to the vehicle
    • FSS systems can be approved as a “component” by test in a defined test rig or installed in a specific engine compartment
    • R107 covers the following vehicles exceeding 22 passengers:
      – Class I (standing passengers)
      – Class II (seated and standing passengers. City buses)
      – Class III (seated passengers. Coaches)
    • Time frame of implementation:
Vehicle Class FSS according to R107 becomes compulsory Vehicle types Final date
Class III 11th of July 2018 New vehicle types 11th of July 2019
Class I and II 1st of September 2020 New vehicle types 1st of September 2021

Class III – Coaches

Class I and II – City buses
