Scope of application: It is applicable to the test method for judging whether the building material has flammability under the specified conditions.

Standards: GB/T8626 "Test Methods for Flammability of Building Materials" and ISO 11925-2:2002 "Reaction to fire tests -- Ignitability of building products subjected to direct impingement of flame -- Part 2: Single-flame source test"

Main parameters:

The whole set of configuration: the testing machine is composed of a control box, a combustion chamber body, a burner, a solenoid valve, a high-pressure igniter, a signal control line and a sample support;

Power supply voltage: AC220V±10%, 50Hz;

Gas pressure: 10kpa~50kpa;

Flue air velocity: under the condition of only igniting the burner and opening the exhaust hood, the flue flow velocity of the box is 0.7m/s, measured by anemometer, and the accuracy is ±0.1m/s;
