Overview
The JB-Brookfield JB-6065B Touchscreen Needle Flame Test Apparatus is a precision-engineered instrument designed for evaluating the ignition resistance of non-metallic materials under controlled flame exposure conditions. It operates in strict accordance with the thermal ignition hazard assessment methodology defined in IEC 60695-2-2, IEC 60695-11-5, IEC 60695-11-10, and GB 5169.5–2008. The apparatus simulates the effect of a small, localized flame source—such as that produced by a glowing component or overheated wire—on plastic housings, insulating components, and other polymeric parts used in electrical and electronic equipment. Its core principle relies on standardized needle flame application: a precisely dimensioned burner delivers a stable, calibrated hydrocarbon flame at defined temperature gradients and spatial positioning relative to the test specimen. This enables reproducible determination of whether a material self-extinguishes within specified time limits after flame removal, or propagates fire under sustained thermal stress.
Key Features
- Integrated PLC-based control system paired with a 7-inch high-resolution color touchscreen (Weinview, Taiwan), providing intuitive navigation, real-time parameter monitoring, and secure data logging.
- Wireless electronic remote control for operator safety during flame initiation and test sequence execution—eliminating proximity hazards during ignition phases.
- High-precision needle burner assembly: stainless steel construction with nominal inner diameter of 0.5 mm ± 0.1 mm, outer diameter ≤ 0.9 mm, and minimum length of 35 mm—ensuring consistent fuel flow dynamics and flame geometry.
- Factory-calibrated flame temperature gradient verification system included as standard: features an imported German Type K thermocouple (Ø0.5 mm) embedded in a traceable copper calibration block (Ø4.00 ± 0.01 mm, mass 0.58 ± 0.01 g), enabling on-site validation per IEC 60695-11-10 Annex A.
- Adjustable burner orientation mechanism supporting both vertical alignment (for accurate flame height setting at 12 mm ± 1 mm) and fixed 45° tilt (for standardized specimen exposure per test protocols).
- Blackened internal chamber (0.5 m³ volume) minimizes optical interference and enhances thermal stability; exhaust port (Ø100 mm) facilitates safe venting of combustion byproducts through external ducting.
- Digital timer with ±0.1 s accuracy and programmable exposure range (1.0–999.9 s) ensures compliance with time-critical pass/fail criteria across multiple test durations.
Sample Compatibility & Compliance
The JB-6065B accommodates flat, rigid, or semi-rigid specimens up to 150 mm × 150 mm × 13 mm, including molded plastics, laminates, circuit board substrates, and insulating films. Specimens are mounted vertically on a non-combustible holder and positioned at a fixed 200 mm ± 5 mm distance from the underlying ignition substrate—a 10 mm-thick pine board covered with standardized silk paper (12–30 g/m²). All mechanical clearances—including the critical 8 mm ± 1 mm gap between burner tip and specimen surface—are maintained via precision-machined fixtures. The apparatus conforms to the physical and procedural requirements of IEC 60695-2-2 Clause 6, IEC 60695-11-5 Annex B, and GB 5169.5–2008 Section 5. It supports full auditability for GLP and ISO/IEC 17025-accredited laboratories, with all calibration records, firmware version logs, and user access timestamps retained internally.
Software & Data Management
While the JB-6065B operates primarily via its embedded HMI interface, it supports optional RS-232/USB data export for integration into laboratory information management systems (LIMS). Test parameters—including start time, flame duration, observed afterflame/afterglow times, and pass/fail status—are stored with timestamp and operator ID. Firmware complies with IEC 62443-3-3 cybersecurity principles for industrial control devices. For regulated environments (e.g., medical device or automotive component testing), optional 21 CFR Part 11-compliant software modules are available upon request, delivering electronic signatures, audit trails, and role-based access control.
Applications
This apparatus is routinely deployed in quality assurance labs of electronics manufacturers, third-party certification bodies (e.g., UL, TÜV, SGS), and national metrology institutes for flame propagation testing of enclosures, connectors, switches, PCB edge guards, and cable management components. It supports failure mode analysis during design validation, comparative material screening (e.g., halogen-free vs. brominated flame-retardant polymers), and root cause investigation of field-reported fire incidents. Its reproducibility makes it suitable for inter-laboratory round-robin studies and proficiency testing programs administered under ISO/IEC 17043.
FAQ
What gas supply specifications are required for compliant operation?
Butane or propane gas with ≥95% purity must be supplied via an air-tight, pressure-regulated system. Compressed air contamination invalidates flame temperature profiles and violates IEC 60695-11-10 calibration prerequisites.
Is periodic recalibration of the thermocouple mandatory?
Yes. Per IEC 60695-11-10, the calibration thermocouple and copper block must be verified annually using NIST-traceable reference standards or equivalent national metrology institute certification.
Can the JB-6065B be integrated into automated test sequences?
Yes—via optional Modbus RTU communication protocol support, enabling synchronization with robotic specimen handlers and centralized test orchestration platforms.
Does the apparatus meet CE or UKCA marking requirements?
The JB-6065B complies with the EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU when installed with certified power conditioning and grounding per EN 61326-1. CE Declaration of Conformity is provided with shipment.
What maintenance intervals are recommended for long-term reliability?
Burner nozzles should be inspected weekly for carbon deposition; the exhaust duct requires quarterly cleaning; touchscreen firmware updates are issued biannually and distributed via secure vendor portal.
