Flammability Test Chamber UL1581 Flame and Tests FTI And VW-1
Standard:
UL1581 ‘Reference Standard for Electrical Wires, Cables, and Flexible Cords’ flame test.
The UL 1581 is an internationally recognised standard test for evaluating fire safety for electric cables. The FTT UL 1581 test for flammability of cable materials gives a preliminary indication of their suitability for a particular application. The apparatus is supplied as a complete system incorporating all the features necessary for ease of use and safety. It conforms to UL 1581 vertical specimen Bunsen Burner tests and associated international standards. These are:
1060. Vertical Flame and FT1 Tests
1061. Cable Flame Test
1080. VW-1 (Vertical Specimen) Flame Test
1090. Horizontal-Specimen Appliance-Wire Flame Test
1100. Horizontal-Specimen / FT2 Flame Test
UL 1581 VW-1This was the first flame test developed for studying how flames spread on wire and cable. The test is performed with a 24′ wire and a Tirrill burner. Two clamps hold the single sample vertically. The burner is mounted at a 20° angle and applied for 15 seconds, then reapplied four more times each time the wire stops burning. If the sample doesn’t burn more than 60 seconds after any of these burning sessions, or if less than 25% of the indicator flag burns, or the cotton batting is ignited during the test, the wire passes. A “tray rated” cable must pass this test as well. Flammability Testing Equipment
