**Final report documenting the MPS and the results of Halon 1301 testing on the four required fire scenarios is in final review within the FAA and will be published shortly.**

## Bulk Load Scenario

**Cargo Compartment = 2000 ft****3**

**Leak Rate = 50 CFM**

**Fire Load = 178 card board boxes (30% of Vol.) containing 2.5 lbs of shredded paper**

**Instrumentation = Type K Thermocouple, Gas Analyzer**

**Ignition = Nichrome wire wrapped around folded paper towels**** **

**System Activation = 1 min. after one of the ceiling T/C reaches 200 ****o****F**

**Test Duration = Five tests @ 30 minutes each.**

**Bulk Load Scenario**

## Containerized Load Fire Scenario

**Cargo Compartment = 2000 ft****3**

**Leak Rate = 50 CFM**

**Fire Load = 33 card board boxes **
**inside an LD3. Three LD3 in Cargo**

**Instrumentation = Type K Thermocouple, Gas Analyzer**

**Ignition = Nichrome wire wrapped around folded paper towels **

**System Activation = 1 min. after one of the ceiling T/C reaches 200 ****o****F**

**Test Duration = Five tests @ 30 minutes each.**

**Containerized Load Fire Scenario**

## Surface Burning Fire Scenario

**Cargo Compartment = 2000 ft****3**

**Leak Rate = 50 CFM**

**Fire Load = 0.5 U.S. Gallon of Jet A **
**fuel (with 13 oz of gasoline)**

**Instrumentation = Type K Thermocouple, Gas Analyzer**

**Ignition = Arc created by sparking electrodes**

**System Activation = 1 min. after one of the ceiling T/C reaches 200****o ****F.**

**Test Duration = 5 minutes**

**Surface Burning Fire Scenario**

## Exploding Aerosol Can Fire Scenario

**Cargo Compartment = 2000 ft****3**

**Leak Rate = 50 CFM**

**Fire Load = 0.2 lb. Propane, 0.6 lb. of**
**Denatured Alcohol, 0.2 lb of water**

**Instrumentation = Type K Thermocouple, Gas Analyzer**

**Ignition = Arc created by sparking electrodes**

**Simulator Activation = When the agent, at 2 feet from the floor, is at the minimum vol. design concentration**

**Test Duration = 15 seconds after the activation of the simulator**

**Exploding Aerosol Can Fire Scenario**

## Acceptance Criteria for Gaseous Agents

**Acceptance Criteria for Gaseous Agents**

## Non-gaseous agents or systems

**Bulk load, containerized load and surface burning fire scenarios are identical to the requirements for gaseous agents. **

**Water mist testing by FAA and FIREDASS using various systems has shown significantly lower ceiling temperatures than those achieved using Halon 1301.**

**Additional FAA water mist testing is planned to determine the ability of the system to prevent the rupture and ignition of actual aerosol cans.**

**Imposing the aerosol can scenario on a water mist system will eliminate the possibility of certifying that type of system to the MPS.**

## Future Activities

**Complete MPS testing with 8 Yulian acoustic water mist nozzles. Conduct aerosol can testing. May 2000.**

**Conduct all required MPS testing using FE-25 (HFC125) agent. June 2000.**

**Finalize and publish MPS requirements for non-gaseous agents or systems.**
