Needle-Flame Tester
Standard:IEC60695-11-5 Test flames-Needle-flame test
method-Apparatus,confirmatory test arrangement and guidance
Application:This part of IEC60695 specifies a needle-flame test to simulate the
effect of a samll flame which may result from fault condition, in
order to assess by a simulation technique the fire hazard.
Test sample:Lighting, low-voltage electrical appliances, household appliances,
machine tool electric appliance, electric motor, electric tools,
electronic instruments, electrical instruments, electrical
connector, such as electrical and electronic equipment and parts,
components, including insulation materials, engineering plastic or
other solid combustible materials.
Feature:The Needle Flame Tester consists of a Ф0.9mm needle-shaped burner
that tilts with the angel of 45°and provide it with butane gas. The
fire hazard of the equipment when there is flammule inside the
equipment that caused due to the fault condition is assessed by
whether the specimen can be ignited or the combustion time and
length.
