IEC60695-11-5 test flames-needle-flame test method-apparatus
Application
This part of the IEC60695 specifies a needle-flame test to simulate the effect of a samll flame which may result from faulty conditions, in order to assess the fire hazard by a simulation technique.
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 angle of 45°and provides it with butane gas. The equipment assesses whether the specimen can be ignited by measuring the possible combustion time and length.
