Yanei DG10-D Plus Solid Combustion Rate Tester (Image-Based Method)

Overview

The Yanei DG10-D Plus Solid Combustion Rate Tester is an image-based, fully automated instrument engineered for precise determination of combustion propagation capability in solid materials—specifically powders, granules, and pastes. It operates on the principle of high-resolution visual flame morphology tracking combined with near-infrared (NIR) thermal signature detection to quantify linear flame front velocity across standardized test beds. Designed in strict alignment with UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Section 33.2.4, Test N.1), GB/T 21618–2008, GB 5085.4, GA/T 536, and NY/T 1860 Part 15, the system delivers repeatable, auditable, and regulation-compliant data for flammability classification under hazardous goods transport, waste characterization, agrochemical safety assessment, and industrial process hazard analysis.

Key Features

• Integrated dual-mode ignition system: electrically heated silicon nitride rod (≥1000 °C surface temperature) and compressed gas spark ignition—both fully embedded and auto-validated prior to test initiation
• Real-time combustion monitoring via industrial-grade CCD camera (1280×960 resolution, 60 fps) synchronized with NIR array sensor (750–1400 nm spectral range) for robust flame localization under variable ambient lighting
• Automated sample compaction using a calibrated lifting jig with ergonomic dual-handled mold carriage—ensuring consistent packing density per UN and GB/T requirements
• Dedicated quartz combustion substrate (high-purity fused silica, continuous service up to 1100 °C) with engraved 0–250 mm metric scale for sub-millimeter spatial referencing
• Embedded industrial PC (Intel Core i5, 8 GB RAM, 128 GB SSD) running real-time Linux-based firmware with 10.1″ capacitive touchscreen HMI—no external computer required for operation
• Red emergency stop button with hardware-level power cutoff (IEC 60204-1 compliant), plus optional remote start via IR remote or IEEE 802.11n wireless command interface
• Full test automation: auto-triggered timing upon flame onset detection, continuous frame-by-frame flame centroid tracking, real-time velocity calculation (mm/s), and pass/fail classification per selected standard

Sample Compatibility & Compliance

The DG10-D Plus accommodates heterogeneous solid forms including metallic powders (e.g., aluminum, magnesium), organic crystals (e.g., sulfur, nitrates), polymer granules, pharmaceutical intermediates, and pesticide formulations. Its modular sample holder and adjustable mold geometry conform to stacking dimensions specified in UN Test N.1 (100 mm × 10 mm × 3 mm cross-section) and GB/T 21618 (250 mm length bed). All measurement outputs—including raw video streams, thermal intensity profiles, time-stamped flame position coordinates, and calculated propagation rate—are timestamped, digitally signed, and stored with full audit trail metadata. The system supports GLP/GMP-aligned workflows through optional 21 CFR Part 11-compliant software modules (electronic signatures, user access tiers, change control logs).

Software & Data Management

Pre-installed YaneiCombust v3.2 software provides intuitive workflow navigation, real-time visualization of flame progression overlays, and export of structured CSV/Excel reports compliant with regulatory submission templates. Video archives are encoded in H.264 (MP4) with embedded EXIF metadata (camera model, exposure time, lens focal length, ambient RH/temperature). Network deployment enables centralized management: one administrator workstation can monitor, schedule, and retrieve data from up to 16 instruments via secure Wi-Fi mesh (WPA3-Enterprise). Data integrity is enforced through SHA-256 hash verification on all exported files and automatic backup to NAS or cloud storage (SFTP/HTTPS endpoints supported).

Applications

• Hazardous materials classification for UN/DOT/ADR/IATA shipping documentation
• Regulatory compliance testing for hazardous waste disposal under EPA and China MEE frameworks
• Formulation screening of energetic materials, battery cathode precursors, and pyrotechnic compositions
• Quality control of industrial powders (e.g., food additives, catalysts, pigments) where unintended exothermic reactivity poses handling risks
• Research into flame inhibition mechanisms and fire-retardant additive efficacy in polymeric matrices
• Validation of safety data sheets (SDS) Section 9 physical and chemical properties for REACH and GHS classification

FAQ

What standards does the DG10-D Plus directly support?
It natively implements UN Manual of Tests and Criteria Test N.1, GB/T 21618–2008, GB 5085.4, GA/T 536, and NY/T 1860 Part 15—with configurable pass/fail thresholds and report templates aligned to each.
Is calibration traceable to national metrology institutes?
Yes—spatial calibration uses NIST-traceable reticle targets; timing accuracy is verified against GPS-synchronized atomic clock references; temperature validation follows ISO/IEC 17025 procedures using calibrated thermocouples.
Can the system integrate with LIMS or enterprise QA platforms?
Yes—via RESTful API (JSON/XML) and OPC UA protocol support for bidirectional data exchange with LabWare, Thermo Fisher SampleManager, and Siemens Opcenter Quality.
What maintenance is required for long-term operational reliability?
Annual verification of optical path alignment, NIR sensor responsivity, and quartz substrate integrity is recommended; no consumables beyond standard cleaning reagents and optional replacement ignition rods.
Does the instrument meet electromagnetic compatibility (EMC) requirements for laboratory environments?
Yes—it complies with IEC 61326-1 (industrial EMC) and IEC 61000-4 series immunity testing, certified for CE marking and CCC certification in China.
