IEC60695-11-5 Needle Flame Test Method Apparatus

IEC60695-11-5 Needle Flame Test Method Apparatus
 

Instrument

The Needle Flame Tester is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator. The Needle Flame Tester consists of a diameter of 0.9mm needle burner that tilts to 45degree  from the vertical and is fueled with butane gas. The test time for the temperature of the standard copper block to increase from 100 degree to 700 degree shall be 23.5s. Test flame height is adjusted 12mm.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 instrument is designed to conform to IEC60695-11-5, IEC60695-2-2 and other most commonly used standards in the market.

Application

Insulation and combustible materials used inside electrical and electronic products may propagate flames when a failed component ignites, which may develop into a fire that endangers the safety of operators and product operation. The Needle Flame Tester is used to assess the fire hazard of such component materials. The test is performed to determine that the test flame does not cause ignition of parts, or that a combustible part ignited by the test flame has a limited duration of burning or a limited extent of burning, without spreading fire by flames or burning or glowing particles falling from the test specimen.
