Needle-Flame Tester

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.

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.
