Summary:

Standard: UL1581 sect 1080.1~1080.14, and has get recognition of guangzhou meihua UL. VW-1 (Vertical-specimen) burning Flame Test.

Features:

(1) It’s Economy applicable and has been widely used in wire and cable industry.

(2) Parameters detailed: The test is done in a laboratory whose volume is 4.32 cubic meters.

Test method: Adjust the height of the flame, put the flame top under the specimens to burn for 15s, then put out for 15s. Examine the specimens’ burning situation after Repeating doing this for 5 times. You can set the burning and fire-out time freely, also repetitions, and it can be operated automatically.
