Overview
The TESTech TTech-GBT21618 Combustion Rate Analyzer is a precision-engineered instrument designed to quantify the linear flame propagation velocity of flammable solid materials under standardized thermal ignition conditions. It operates on the principle of controlled horizontal flame spread along a geometrically defined sample geometry—specifically, a triangular cross-section combustion strip formed in a reusable anodized aluminum mold. The device measures the time required for flame front advancement over a fixed 250 mm length, enabling calculation of combustion rate in mm/s—a critical parameter for hazard classification, dust explosion risk assessment, and regulatory compliance evaluation of industrial powders, granules, and pastes.
Key Features
- Compliant with UN Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria (Rev. 7, Section 33.2.1) and GB/T 21618–2008 “Dangerous Goods – Test Method for Burning Rate of Flammable Solids”
- High-reproducibility sample molding system featuring a precision-machined, anodized aluminum triangular mold (250 mm length, 10 mm height × 20 mm base), engineered for dimensional stability up to 400 °C
- Dual confinement plates extending 2 mm above the mold profile ensure consistent lateral flame containment and eliminate edge effects during propagation
- Calibrated gas burner assembly delivering stable ignition at ≥1000 °C with minimum 5 mm flame diameter—verified per ASTM E2021 and ISO/IEC 17025 traceable procedures
- Non-combustible quartz test plate with low thermal conductivity (≤1.4 W/m·K) minimizes substrate heat sink interference and supports uniform thermal boundary conditions
- Modular, benchtop architecture with integrated flame observation port and optional high-speed imaging interface (up to 1000 fps) for detailed combustion front tracking
Sample Compatibility & Compliance
The TTech-GBT21618 accommodates heterogeneous solid-phase samples including fine powders (D50 < 150 µm), agglomerated granules (0.1–3 mm), and viscous pastes (yield stress < 500 Pa). Sample preparation follows strict conditioning protocols per GB/T 21618: moisture content ≤0.5% w/w, bulk density within ±5% of reference value, and compaction force standardized at 10 N applied via calibrated plunger. All test reports generated by this system support audit-ready documentation aligned with GLP (Good Laboratory Practice) frameworks and are compatible with FDA 21 CFR Part 11–compliant electronic record systems when integrated with validated software modules.
Software & Data Management
While the base TTech-GBT21618 operates as a manually timed, observer-driven system, it supports optional digital integration via USB-triggered timing module and RS-485 serial interface. When paired with TESTech’s certified CombustionRate Suite v3.2 (Windows 10/11, 64-bit), users gain automated flame-front detection using contrast-based edge tracking, real-time rate calculation, statistical deviation reporting (n ≥ 3 replicates), and export to CSV, PDF, or XML formats compliant with ISO 17025 clause 7.8.2. Audit trails—including operator ID, timestamp, environmental ambient temperature/humidity logs, and calibration certificate references—are embedded in each report to satisfy GMP and regulatory submission requirements.
Applications
- Hazard classification of new chemical substances under UN GHS Category 1–3 for flammable solids
- Pre-screening of metal powders (e.g., Al, Mg, Ti alloys) prior to additive manufacturing process qualification
- Comparative evaluation of flame-retardant additives in polymer composites and battery electrode slurries
- Supporting DSEAR (UK), ATEX (EU), and NFPA 484 hazard analysis workflows for powder handling facilities
- Generating input data for computational dust explosion modeling (e.g., PHA, MIE correlation studies)
- Validation of safety data sheet (SDS) Section 9 physical hazards statements in accordance with CLP Regulation (EC) No 1272/2008
FAQ
What standards does the TTech-GBT21618 strictly comply with?
It is fully aligned with GB/T 21618–2008 and UN Manual of Tests and Criteria, Part III, subsection 33.2.1. Instrument validation includes inter-laboratory round-robin testing per ISO/IEC 17043 guidelines.
Can the analyzer be used for hygroscopic or thermally unstable materials?
Yes—provided samples are handled under controlled RH (<30%) and tested within 15 minutes of mold loading; optional glove-box integration is available for inert-atmosphere operation.
Is third-party calibration certification included?
Each unit ships with a factory-issued calibration certificate traceable to NIM (National Institute of Metrology, China) for mold dimensions, burner temperature profile, and quartz plate thermal properties.
Does the system meet requirements for regulatory submissions to ECHA or US CPSC?
Test reports generated using validated protocols and documented chain-of-custody procedures are accepted as Tier 1 evidence for REACH Annex VII–VIII dossiers and CPSC 16 CFR Part 1500.3(c)(6)(ii) hazard determinations.
