The Key Stroke UL94 Horizontal Vertical Combustion Testing Equipment is a user-friendly, cost-effective solution for testing plastic flammability, tailored for small-to-medium enterprises (SMEs) and laboratories. It uses a key stroke control system (instead of touchscreen) for simple, reliable operation—ideal for users who prefer tactile buttons over touch interfaces. Compliant with UL94, GB/T2408-2008, and IEC60695-11-10 standards, it performs horizontal (20°, 45° angles) and vertical (90° angle) combustion tests, automatically recording critical data (flame time, after-flame time) to determine material ratings (V-0 to HB). Key features include a ≥0.5m³ test chamber (adequate for most plastic samples), automatic ignition, and burner auto-return—balancing functionality with ease of use for daily quality checks.
• Reliable Key Stroke Operation: Tactile buttons (instead of touchscreen) reduce failure risks in dusty or high-humidity environments. Clear LED indicators show test status (e.g., "Flame Applied," "Test Complete"), simplifying operation for new users.
• Stable Combustion System: Burner with adjustable flame height (20~175mm) and fixed Ø9.5mm nozzle ensures consistent flame intensity. Gas pressure regulating valve and U-shaped pressure gauge prevent flame fluctuations.
• Durable & Compact Design: 110650125CM appearance size fits small laboratory spaces. Steel plate outer casing (anti-rust) and heat-resistant sample fixtures (supports various plastic shapes) ensure long-term use.
This equipment is perfect for:
• SMEs & Small Labs: Conducting in-house quality control for plastic parts (e.g., toy components, small electronic casings) without relying on external testing services.
• Educational Institutions: Teaching materials science and fire safety in universities, with simple operation suitable for student experiments.
• Plastic Fabricators: Testing raw plastic materials (e.g., pellets, sheets) before production to ensure compliance with customer flammability requirements.
• Local Inspection Offices: Performing on-site tests for small batches of plastic products (e.g., household goods) to verify safety compliance.
