According to GB4610-2008 plastic hot air furnace method for determination of lighting temperature, it is designed and manufactured, which fully complies with 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. GB4610-2008 version of DW-04 lighting temperature tester Test principle: In the heating chamber of the hot air furnace, use different temperature heating patterns and use a small flame to directly ignite the escaping gas at the opening above the furnace to determine the flash ignition temperature. The spontaneous ignition temperature is determined by the same method as the flash ignition temperature, but no flame is applied. 【Relevant Standards】

【Scope of application】： According to GB4610-2008 Plastic hot air furnace method for the determination of lighting temperature, it is fully compliant with 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. GB4610-2008 version of DW-04 lighting temperature tester test principle: In the heating chamber of a hot air furnace, the flash ignition temperature is determined by heating the style at different temperatures and using a small flame to light the escaping gas directly at the opening above the furnace. The spontaneous ignition temperature is measured by the same method as the flash flame temperature, but no flame is applied.
