Product Description:
Also known as: GB4610-2008 ignition temperature tester
GB/T9343-2008 plastic hot air furnace ignition temperature tester
DX8602 ignition temperature tester is designed and manufactured in
accordance with GB4610-2008 "Determination of Ignition Temperature
of Plastic Hot Air Furnace Method" and GB/T9343-2008 "Test Method
for Combustion Performance of Plastics - Determination of Flash
Ignition Temperature and Spontaneous Ignition Temperature", which
fully conforms to GB4610-2008 and meets the standard requirements
of ISO871-2006, and is used to assist in testing the combustion and
flame retardant properties of plastic materials.
Compared with the GB4610-1984 version of the standard, the 2008
version of the standard cancels the term of ignition temperature,
adds flash ignition temperature, auto-ignition temperature and
calctile combustion, and the test calculation results are changed
to flash ignition temperature and auto-ignition temperature. The
test instruments required in the 2008 version have also changed
greatly from the original standard.
Concepts related to the test results:
Flash-ignition temperature (FIT): The lowest temperature at which
enough flammable gas is ignited when a flame is applied under
specified test conditions.
Self-ignition temperature (SIT): The lowest temperature at which it
ignites by heating without any ignition source under specified test
conditions.
Glowing combustion is a material in which there is no flame in the
solid phase and the combustion area is accompanied by luminescence.
DX8602 Ignition Temperature Tester Test Principle:
In the heating chamber of a hot air furnace, the flash ignition
temperature is determined by heating the temperature at different
temperatures, and a small flame is used to ignite the escaping gas
directly at the opening above the furnace. The autoignition
temperature is determined in the same way as the flash ignition
temperature, but no flame is applied.
