Scope of Application

【Operating Instructions】

Designed and manufactured in accordance with GB/T 4610-2008 "Plastics — Determination of ignition temperature by the hot air furnace method", this instrument fully complies with GB 4610-2008 and ISO 871:2006. It is used to assist in testing the combustion and flame retardant properties of plastic materials.The specimen is heated to different temperatures in the heating chamber of a hot air furnace. A small flame is applied directly to the opening above the furnace to ignite the escaping gases to determine the Flash Ignition Temperature. The Spontaneous Ignition Temperature is determined using the same method but without the application of an external flame.

Scope of Application

Designed and manufactured in accordance with GB/T 4610-2008 "Plastics — Determination of ignition temperature by the hot air furnace method", this instrument fully complies with GB 4610-2008 and ISO 871:2006. It is used to assist in testing the combustion and flame retardant properties of plastic materials.

Test Principle (GB 4610-2008):
The specimen is heated to different temperatures in the heating chamber of a hot air furnace. A small flame is applied directly to the opening above the furnace to ignite the escaping gases to determine the Flash Ignition Temperature. The Spontaneous Ignition Temperature is determined using the same method but without the application of an external flame.
