The Single Wire Cable Burning Tester is a precision flammability test system designed to assess the flame-retardant performance of single wires and cables under controlled laboratory conditions. It provides stable flame generation, accurate sample positioning, and automated monitoring for repeatable and reliable results. The instrument is widely used in electrical, electronics, and appliance industries to ensure product compliance with international safety standards.
Standards
(1) IEC 60332 – Tests on electric and optical fiber cables under fire conditions.
(2) GB/T 19666-2005 – Flame retardant performance of single wires and cables.
(3) GB 12972 – Test method for burning characteristics of wires and cables.
(4) GB 13033 – Vertical flame test for insulated wires and cables.
(5) MT 818 – Military standard for electrical wire flammability.
(6) MT 386 – Standard for wire and cable flame testing.
(7) ISO 5656 – International method for flame testing of electrical cables.
Features
(1) Stable Bunsen burner flame with adjustable height (20 mm – 190 mm) for precise testing.
(2) Movable test beam with 45° inclination for accurate positioning relative to cable diameter and thickness.
(3) Programmable flame duration (0–999.9 s) for repeatable test cycles.
(4) Supports high-purity propane gas or liquefied petroleum gas as combustion source.
(5) Suitable for wires and cables of 600 ± 25 mm length.
(6) Durable electrostatic sprayed steel construction for long-term laboratory use.
(7) Easy-to-operate controls for adjusting gas and airflow rates.
(8) Compact dimensions for laboratory integration (L × W × H: 60 × 45 × 156 cm).
