Overview of Facilities

Inflammability Test System:

Tests 1, 4, 8 and 18

Ignites the standard flame source.

Used in Tests 4 and 8, overload tests.

Power supply for Test 18.

Measures temperature of electric wires in Test 4.

Heats the inside of the chamber.

For substituting a gas inside the chamber.

Supplies a standard gas into the chamber.

Holds samples. Holders for various test types are available.

Record pressure and temperature inside the chamber.

Monitors oxygen density inside the chamber.
