Однопроводный / кабельный прибор для испытания вертикального сгорания

Применимые критерии

The tester adheres to global and domestic regulations, including:

• IEC 60332 Series: Evaluates flame propagation in single wires (IEC 60332-1/2) and bunched cables (IEC 60332-3).
• UL 2556/94: Assesses flame retardance for VW-1 and 5VA/B ratings.
• GB/T 18380: Chinese standards for single-wire flame spread tests.
• GB 17761-2024: Mandates fire resistance for e-bike wiring.

Основные параметры

Принцип работы

The tester employs a 1 kW propane-air flame applied to vertically mounted cables. Sensors monitor flame spread, smoke generation, and temperature changes in real time. The system automatically adjusts flame height and angle (45°) to simulate worst-case fire scenarios. Safety features include emergency stop buttons and explosion-proof enclosures.

Принцип испытания

1. Подготовка образцов: Condition cables at 23±10℃ and 50±20% humidity for 16 hours.
2. Ignition: Apply flame to the cable’s midpoint for a predefined duration.
3. Combustion Monitoring: Track flame propagation distance and self-extinguishing time.
4. Критерии соответствия / несоответствия: Damage must not exceed 50 mm from the upper clamp for compliance.

Key Advantages

• Соблюдение: Meets IEC, UL, and GB standards for global market access.
• Точность: Adjustable flame parameters ensure repeatable results.
• Эффективность: Automated controls reduce testing time by 40%.
• Safety: Dual-layer protection prevents operator exposure to hazards.

This tester empowers manufacturers to design safer cables, minimizing fire risks and accelerating product certification. By identifying weaknesses early, it supports cost-effective quality control and innovation.
