Needle flame Tester (Model: NF-1)
1. Introduction
Needle flame test apparatus can meet the test requirements of 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 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.
