Evaluating flame retardancy of plastics (UL-94) | PLASTIC FLAMMABILITY TESTER / No.252-UL-94 | Evaluating flammability of wires, cables, and cords (UL-1581) | ELECTRIC WIRE FLAMMABILITY TESTER / No.252-UL-1581

• No.252-UL-94 PLASTIC FLAMMABILITY TESTER
• No.252-UL-1581 ELECTRIC WIRE FLAMMABILITY TESTER

Overview of PLASTIC FLAMMABILITY TESTER

This tester is used to evaluate the burn-resistance of plastic according to the vertical flaming test (V) and horizontal flaming test (HB).
The tester has been improved so that the operator can conduct the test easily by using the jog dial type controller and the touch panel display also equipped with voice guidance.
With these functions, the operator can concentrate in watching the condition of the test specimen while controlling the burner to adjust the distance between the flame and the test specimen.
Adding the option jigs, the tester will enable to carry out other test methods (5V, VTM, HBF, HF).
