HAIDA HD-R807 Horizontal & Vertical Combustion Tester

Overview

The HAIDA HD-R807 Horizontal & Vertical Combustion Tester is a precision-engineered benchtop instrument designed to evaluate the flammability characteristics of solid materials—primarily plastics, textiles, foams, and composite laminates—under standardized horizontal (HB) and vertical (V-0, V-1, V-2) burning configurations. It operates in strict accordance with the fundamental principles of flame propagation assessment defined in UL 94, IEC 60695-11-10, GB/T 2408, ISO 9772, and ASTM D3801. The system employs a calibrated Bunsen-type burner delivering a reproducible 20 mm high blue flame (propane or butane fuel), precisely positioned relative to the specimen holder via micrometer-adjustable fixtures. Flame application duration, post-ignition observation time, afterflame and afterglow durations, and specimen dimensional stability are measured using integrated digital timers and high-contrast visual observation chambers with non-reflective black interior lining. Its dual-axis specimen mounting mechanism enables rapid reconfiguration between horizontal and vertical test orientations without tooling changes.

Key Features

• Compliant dual-mode operation: fully supports UL 94 HB, V-0, V-1, and V-2 classification protocols within a single platform
• Integrated flame height calibration gauge and gas flow meter for consistent 20 mm flame geometry per UL 94 Section 8.2
• Adjustable specimen holder with precision-machined stainless steel clamps accommodating specimens up to 125 mm × 13 mm × 12.5 mm (L × W × H)
• High-resolution digital timer (0.1 s resolution) with independent start/stop triggers for afterflame and afterglow measurement
• Fire-resistant observation chamber with tempered glass viewport, internal LED lighting, and forced-air ventilation exhaust interface
• Gas supply safety interlock system with manual shut-off valve, pressure regulator, and leak-tested stainless steel tubing
• CE-marked electrical architecture compliant with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards

Sample Compatibility & Compliance

The HD-R807 accommodates rigid and semi-rigid flat specimens meeting UL 94 thickness requirements (typically 3.2 mm, 1.6 mm, or 0.8 mm), including injection-molded plaques, extruded sheets, laminated composites, and coated fabrics. Specimens must be conditioned per ISO 291 (23 ± 2 °C, 50 ± 5 % RH) for minimum 48 hours prior to testing. The instrument satisfies regulatory acceptance criteria for flammability certification under RoHS-compliant material qualification workflows and is routinely deployed in third-party testing laboratories accredited to ISO/IEC 17025. It supports full traceability documentation required for GMP-aligned quality systems and meets mechanical design prerequisites outlined in EN 60695-11-4 for fire hazard testing apparatus.

Software & Data Management

While the HD-R807 operates as a manually supervised analog-digital hybrid system (no embedded firmware or touchscreen UI), it is fully compatible with external laboratory data management ecosystems. Test parameters—including ignition time, flame duration, drip behavior, and classification outcome—are recorded in standardized UL 94 test report templates. These reports integrate seamlessly into LIMS platforms such as LabWare LIMS, Thermo Fisher SampleManager, or custom SQL-based QA databases via CSV export. All timing events are logged with timestamped audit trails, supporting compliance with FDA 21 CFR Part 11 when paired with validated electronic signature modules and controlled document revision workflows.

Applications

• Pre-certification screening of polymer formulations for UL 94 V-0/V-1/V-2 rating eligibility
• Quality control verification of incoming raw materials in automotive interior component manufacturing
• Comparative flame retardancy evaluation during R&D of halogen-free flame-retardant additives
• Regulatory submission support for medical device housing materials (IEC 60601-1 Clause 11.1)
• Fire safety validation of printed circuit board substrates (e.g., FR-4, polyimide) per IPC-4101
• Testing of packaging materials subject to UN/DOT 4G/4H1 hazardous goods transport regulations

FAQ

Does the HD-R807 comply with UL 94 Edition 6 (2022)?
Yes—the mechanical configuration, burner specification, specimen dimensions, and timing logic align with all mandatory clauses of UL 94-2022, including Annex A (test report requirements) and Clause 8 (apparatus verification).
Can the instrument be used for ISO 9773 (thin material testing)?
No—ISO 9773 requires a modified specimen support fixture and different flame impingement geometry; the HD-R807 is optimized exclusively for ISO 9772 and UL 94 geometries.
Is calibration certification included with delivery?
Each unit ships with a factory-issued calibration verification report covering burner flame height, gas flow rate, and timer accuracy, traceable to NIM (China National Institute of Metrology) standards.
What safety certifications does the electrical enclosure hold?
The control panel complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking under the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU.
Are spare parts and consumables available globally?
Yes—HAIDA maintains an international distributor network supplying certified burner nozzles, specimen clamps, quartz viewing windows, and UL 94 reference materials (e.g., ABS control sample) with documented lot traceability.
