Horizontal Vertical Specimen Flame Tester

TESTech Instrument (Suzhou) Technologies is one of the leading manufacturers and suppliers of horizontal vertical specimen flame tester in China. Welcome to wholesale premium test equipment at competitive price from our factory. If you have any enquiry about quotation, please feel free to email us.

The TESTech cable horizontal and vertical flame tester is a large combustion cabinet produced strictly in accordance with UL 1581 Sect. 1080.1 to 1080.14 and meets the requirements of the VW-1 vertical-specimen flame test.

It is used for 1060 finished wire and cable FT1 and vertical flame tests, 1061 cable flame tests, 1080 VW-1 vertical-specimen flame tests, 1090 horizontal wire flame tests, and 1100 horizontal specimen or FT2 flame tests, in order to assess the ability of wires, cables, or flexible cords to propagate flame to nearby combustible materials when ignited.

The instrument is economical, widely used in the wire and cable industry, and suitable for evaluating the flame-retardant performance of cable insulation under abnormal conditions such as overheating or overcurrent. The complete test is conducted in a sealed chamber with a volume of 4.54 m3.

Test method: adjust the flame height, place the specimen at the top of the flame, burn for 15 seconds, extinguish for 15 seconds, repeat 5 times, and then inspect the burned condition of the specimen. Burning time, extinguishing time, and repetition count can be set and controlled automatically.
