IEC60695-11-5 Needle flame Tester
1. Introduction
Needle flame tester is designed according to IEC60695-11-5(IEC60695-2-2). It is applicable to ignition hazard test, combustibility test of electronic industry and home electronic appliance. The equipment specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess product and material’s ignition risk and fire resistance by a simulation technique the fire.
The Needle Flame Tester consists of a dia.0.9mm needle burner that tilts to 45 degree from the vertical and is fueled with butane gas. The fire hazard of the specimen is assessed by measuring the burning duration of the specimen, and any ignition of the wrapping tissue and white pine board below the specimen.
The needle flame test apparatus is controlled by single chips and push buttons, the shell is made of coating metal sheet. The test apparatus is built-in air exhaust. The front panel is transparent for easy observation of the experimental process. Avoid gas leakage explosion caused by circuit leakage or short circuit, the equipment has self-contained gas flow size alarm device.
