FIRE TESTING
CLASS C
What is a Class C fire?
Fire class is a term used to denote the type of fire in relation to the combustion material which has ignited. A Class C fire is the burning of flammable gases. This includes gases like butane, propane and petroleum gases that are stored in commercial premises.
All Firexo Fire Class ratings have been achieved through the EN fire tests.
Class C fire rating explained.
Using the Australia & New Zealand guidelines for the test, the test apparatus consists of using a minimum 33kg propane tank, shut-off valve, 7mm orifice plate, and 2m straight tube with a pressure of no less than 5 bar. The apparatus is connected via a hose and setup on a stand or table in a horizontal position. Once the shut-off valve is open, the pipe-end can be ignited.
The fire fighter is then sent in with a single extinguisher and allowed to extinguish the fire at their discretion. In order to pass the test, there must be no flames left and the gas completely extinguished.
For extinguishers of more than 6KG, the extinguisher must extinguish 2 tests with a single extinguisher. For extinguishers of less that 6KG then a single extinguisher is allowed for each test.
You are allowed 3 tests and the extinguisher must pass two of the three to be deemed successful for Class C rating.
