Jiubin JB-5202B Touchscreen Glow-Wire Test Apparatus

Overview

The Jiubin JB-5202B Touchscreen Glow-Wire Test Apparatus is a precision-engineered safety compliance instrument designed to evaluate the fire hazard potential of non-metallic materials and components used in electrical and electronic equipment. It implements the standardized glow-wire ignition test (GWIT) and glow-wire flammability test (GWFI), as defined by IEC 60695-2-10 through -13 and corresponding national standards including GB/T 5169.10–13. The apparatus simulates thermal stress induced by overheated conductive parts—such as malfunctioning resistors or overloaded terminals—under controlled short-duration exposure. Its core measurement principle relies on precise thermal delivery via a calibrated Ni/Cr alloy wire heated to a predefined temperature, followed by quantitative assessment of ignition behavior, flame propagation, and self-extinguishment characteristics of test specimens. Engineered for laboratory-grade repeatability and regulatory traceability, the JB-5202B meets functional requirements for accredited testing laboratories performing routine conformance verification under ISO/IEC 17025 environments.

Key Features

• Integrated 7-inch Weintek color TFT touchscreen HMI with intuitive PLC-based control logic for seamless parameter configuration, real-time monitoring, and automated sequence execution.
• High-stability glow wire assembly using certified Ø4.00 ± 0.04 mm Ni/Cr (77/20) alloy wire—sourced to meet dimensional and compositional tolerances specified in IEC 60695-2-10.
• Temperature regulation system featuring digital PID control and a German-sourced 0.5 mm K-type mineral-insulated thermocouple, ensuring thermal accuracy within ±3 °C across the full 100–1150 °C operating range.
• Precision electromechanical force application mechanism delivering consistent 0.95 ± 0.1 N contact load during specimen penetration—fully compliant with mechanical calibration requirements of Clause 7.3 in IEC 60695-2-10.
• Micro-adjustable 7.0 ± 0.5 mm penetration depth control via solenoid-actuated linear drive, enabling reproducible thermal energy transfer at the material interface.
• DC-motor-driven specimen carriage with ball-screw transmission ensures uniform translational speed (10–25 mm/s), eliminating vibration-induced measurement artifacts during glow-wire approach and dwell phases.
• Triple high-resolution digital timers (glow time, ignition time, flame extinguishing time), each with 0.01 s resolution and independent preset capability—supporting both manual and auto-triggered event logging.
• Standardized test chamber with matte black interior surfaces (<20 lx ambient illumination), fixed 200 ± 5 mm glow-wire-to-substrate distance, and configurable internal volume (0.5/0.75/1.0 m³) to accommodate varying specimen geometries and airflow requirements.

Sample Compatibility & Compliance

The JB-5202B accommodates rigid and semi-rigid polymeric specimens up to 80 × 80 mm in planar dimension and typical thicknesses ranging from 0.5 mm to 13 mm—aligned with sample preparation guidelines in IEC 60695-2-11 and UL 746A. It supports testing of housings, insulators, connectors, printed circuit board substrates, and internal structural components. All operational parameters—including applied force, penetration depth, temperature ramp rate, and dwell duration—are fully adjustable to satisfy variant test protocols across IEC 60335-1 (household appliances), IEC 60884-1 (plugs and socket-outlets), IEC 60598-1 (luminaires), IEC 60950-1 (IT equipment), and GB 4943.1. The apparatus is compatible with GLP-compliant documentation workflows and supports audit-ready data export for regulatory submissions under FDA 21 CFR Part 11 and ISO 17025 clause 7.7.

Software & Data Management

The embedded PLC firmware enables full test sequencing—including preheating, positioning, contact initiation, dwell, retraction, and post-test cooling—with automatic timestamping of all critical events. All timer values, thermocouple readings, current draw, and system status flags are logged internally with UTC synchronization. Data export is supported via USB 2.0 to CSV or PDF report templates pre-formatted for inclusion in test certificates. Optional PC-based software (available separately) provides extended analytics, statistical process control (SPC) charts for GWFI/GWIT trend analysis, and integration with LIMS platforms via TCP/IP or RS-232. Audit trails record operator ID, parameter changes, calibration events, and firmware version history—meeting traceability mandates of ISO/IEC 17025:2017 section 8.9 and EU Decision 768/2008/EC Annex II.

Applications

The JB-5202B serves as a primary evaluation tool in product safety R&D labs, third-party certification bodies (e.g., SGS, TÜV, UL authorized labs), and in-house quality assurance departments. Typical use cases include comparative flammability screening of alternative polymer formulations, validation of flame-retardant additive efficacy, qualification of molded housing materials prior to production release, and root-cause analysis of field-reported fire incidents. Its design facilitates repeatable inter-laboratory correlation studies required for round-robin testing programs aligned with IEC TR 60695-1-30. The apparatus is routinely deployed in compliance workflows supporting CE marking (LVD Directive 2014/35/EU), UKCA, CCC, and PSE certifications.

FAQ

Does the JB-5202B support automated calibration verification per IEC 60695-2-10 Annex B?
Yes—the system includes built-in diagnostic routines for thermocouple linearity checks and force sensor zero-point validation; full calibration certificate generation requires optional traceable reference standards.

Can the chamber volume be upgraded after initial purchase?
Chamber volume is determined by structural frame dimensions; only factory-installed configurations (0.5 m³, 0.75 m³, or 1.0 m³) are available—no field retrofit kits are offered.

Is remote operation possible beyond the included wireless remote control?
The PLC interface supports Modbus RTU over RS-485, enabling integration into centralized lab automation systems; Ethernet connectivity requires optional communication module.

What maintenance intervals are recommended for sustained compliance?
Glow wire replacement every 100 test cycles or when visible deformation occurs; thermocouple verification every 3 months; mechanical alignment check before each daily test session per ISO/IEC 17025 clause 6.4.10.

Are test reports generated by the JB-5202B accepted by CB Scheme National Certification Bodies?
Yes—provided testing is performed under an ISO/IEC 17025-accredited scope, with documented equipment calibration, environmental monitoring, and personnel competency records.
