R107

FIRE SUPPRESSION SYSTEM APPROVED AND IN ACCORDANCE WITH NEW INTERNATIONAL STANDARD R107 IN BUSES AND COACHES

Fogmaker approved in accordance with new international standard R107 for fire suppression systems in buses and coaches.

Fogmaker fire suppression system 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 type approval

UNECE 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 the Fogmaker system for the R107 fire test:

Gross volume “engine compartment”: 4m³
Extinguishant volume: 6,1 litres
Number of spray nozzles: 11
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 min 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.

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)
