Needle-Flame Tester
Product details: Model ZLT-ZY2.
The ZLT 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.
The ZLT 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 0.9mm needle burner that tilts to 45° From the vertical and is fueled with butane gas.
The test time for the temperature of the standard copper block to increase from 100° C ± 5° C to 700° C ± 3° C shall be 23, 5s ± 1.0s. Test flame height is adjusted 12mm ± 1mm. 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. It consists of a tube with a bore 0.5/font> 0.1mm and gas-flow regulating valve for adjustment of the flame height. It shall be used with a pressure regulator.
The instrument is designed to conform to the IEC60695-11-5, IEC60695-2-2 and other most commonly used standards in the market.
