450 and 900 Tilted 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 7-inch color touch screen and PLC, the system comes with a flame calibration system. The shell is made of painted coating metal sheet and built-in air exhaust. The front panel is transparent for easy observation of the experimental process.
