Overview
The Jiubin Instruments JB-6065 Needle Flame Test Apparatus is a precision-engineered benchtop testing system designed to evaluate the flammability resistance of non-metallic materials and components used in electrical and electronic equipment. It operates in strict accordance with the thermal ignition hazard assessment methodology defined in IEC 60695-11-5, GB 4706.1 (equivalent to IEC 60335-1), and GB/T 5169.5–1997 (identical to IEC 60695-11-5:1999). The apparatus employs a standardized butane-fueled micro-flame generated by a vertically oriented stainless-steel needle burner, delivering controlled thermal energy to simulate fault-induced ignition sources such as glowing wires or small arcs. Its core function is to determine whether a material self-extinguishes within a specified time after flame removal—or propagates fire—under defined thermal stress conditions. This makes it indispensable for product safety certification under CCC, CE (LVD), UL recognition pathways, and internal R&D validation in compliance with GLP-aligned laboratory practices.
Key Features
- Stainless-steel needle burner with precise dimensional tolerances: 0.5 mm inner diameter, 0.9 mm outer diameter, and 35 mm effective length—ensuring repeatable flame geometry per IEC 60695-11-5 Annex A.
- High-stability thermocouple-based temperature monitoring system capable of detecting and verifying flame tip temperatures exceeding 1050 °C, with traceable calibration to NIST-traceable reference standards.
- Integrated 6 mm-diameter nickel-chromium temperature conduction rod for accurate thermal response verification; meets the 100 °C → 700 °C ramp requirement of 23.5 ±1.0 s as specified in Clause 7.2.2 of GB/T 5169.5–1997.
- Microprocessor-controlled timing module offering 0.01 s resolution for flame application duration, post-ignition observation period, and inter-test cooldown intervals—fully programmable and logged with timestamped audit trail.
- Adjustable flame height mechanism calibrated to maintain 12 ±1 mm vertical distance between flame tip and test surface, verified using supplied height gauge and ISO 17025-accredited procedure.
- Automatic piezoelectric ignition and flame stabilization circuitry eliminating manual lighting variability and improving operator safety and test reproducibility.
- Flame visualization and measurement support via integrated optical alignment aids and included calibrated height gauge, facilitating consistent setup across operators and laboratories.
Sample Compatibility & Compliance
The JB-6065 accommodates flat, rigid specimens up to 150 mm × 150 mm × 13 mm, including insulating housings, terminal blocks, PCB substrates, and polymer enclosures. Specimen mounting follows IEC 60695-11-5 Clause 8: horizontal or vertical orientation with defined clamping force and edge clearance. All test procedures comply with mandatory requirements for household appliance certification (GB 4706.1), IT equipment (GB 4943.1), and industrial control panels (GB/T 16935.1). The apparatus supports full traceability documentation required for ISO/IEC 17025 accreditation, including calibration certificates for thermocouples, timing modules, and dimensional gauges. It is compatible with standard reference materials such as white pine board (ASTM D143 Grade 2, moisture content 12 ±2%) and filter paper (ISO 6588-1, 12.5 g/m²), both supplied with each unit.
Software & Data Management
While the JB-6065 operates as a standalone hardware platform without embedded software, its timing and event log functions generate ASCII-formatted timestamped records (YYYY-MM-DD HH:MM:SS) stored in non-volatile memory. These logs—exportable via USB-C interface—contain flame-on duration, observed afterflame time, afterglow duration, pass/fail status, and operator ID. The data structure conforms to ASTM E2500-18 Annex A for raw instrument output and supports import into LIMS platforms compliant with FDA 21 CFR Part 11 (electronic signatures enabled via external authentication server). Optional RS-232 or Ethernet modules allow integration with enterprise QA systems for automated report generation aligned with ISO 9001 clause 8.2.4 and IEC 61000-4-29 test record retention policies.
Applications
- Pre-certification screening of polymeric housing materials for Class II appliances and medical device enclosures.
- Root cause analysis of ignition failures during HALT/HASS testing of power supply modules and relay assemblies.
- Comparative evaluation of halogen-free flame-retardant (HFFR) compounds versus brominated formulations under identical thermal insult conditions.
- Verification of material substitution impact following engineering change notices (ECNs) in automotive ECUs and industrial sensors.
- Supporting technical documentation for Declaration of Conformity (DoC) submissions to Chinese CCC and EU NB bodies under Directive 2014/35/EU.
FAQ
What fuel gas is required, and what purity specifications must it meet?
Butane gas with minimum purity of 99.5% (per ISO 8573-1:2010 Class 2) is mandatory. Impurities such as hydrogen sulfide or mercaptans must be below 1 ppm to prevent thermocouple poisoning and burner clogging.
Is the JB-6065 suitable for testing curved or irregularly shaped components?
Only flat, planar surfaces meeting the dimensional constraints of IEC 60695-11-5 Clause 8.1 may be tested. Curved parts require sectioning or fixture-based flattening validated per ISO/IEC 17025 method validation protocol.
How often must the temperature verification test (100 °C → 700 °C) be performed?
Per GB/T 5169.5–1997 Section 10.2, this calibration check shall be conducted before each test series, after any maintenance involving the burner or thermocouple, and at least once per 8-hour shift in continuous operation.
Does the apparatus include test report templates compliant with IEC 60695-11-5 reporting requirements?
Yes—preformatted PDF and Excel templates are provided, covering all mandatory fields: specimen identification, orientation, flame duration, afterflame/afterglow times, failure mode classification (dripping, charring, flaming droplets), and observer signature with date/time stamp.
