Cone Calorimeter: Shorter Fire Test Times & ISO 5660 Compliance
In the race for global product certification, time is the most critical variable. For fire testing laboratories, shorter process times mean getting safer products to market faster.
As international safety standards for rail vehicles (BS 6873), shipping (IMO), and construction (ISO 5660) become increasingly complex, leading laboratories are expanding their capacity to handle lengthy special tests independently of regular measurements. The heart of this expansion is the Cone Calorimeter, the single most important laboratory measuring instrument for modern fire performance evaluation.
As a professional manufacturer of fire safety and laboratory testing instruments, Baoruitong Automation Equipment Co., Ltd. (BRT) presents the ZXLR Cone Calorimeter — engineered to deliver rapid, certification-grade data through precision oxygen consumption calorimetry.
The Science of Certainty: How Cone Calorimeters Work
The cone calorimeter determines the Heat Release Rate (HRR) of combustible materials using the “oxygen consumption method.” This principle states that the amount of heat released is proportional to the amount of oxygen consumed during combustion.
Unlike simple small-scale tests, a cone calorimeter tracks a material’s behavior across multiple fire scenarios, providing critical data on:
- Time to Ignition & Critical Heat Flux
- Mass Loss Rate & Total Mass Loss
- Smoke Release Rate & Total Smoke Output
- Toxic Gas Emission (CO/CO₂)
This data is used not only for fire simulations but for the essential normative evaluation of materials used in high-risk sectors like rail transport, shipping, and high-rise construction.
BRT ZXLR: Precision and Automation for Shorter Lead Times
The BRT ZXLR Cone Calorimeter is designed to meet the rigorous demands of GB/T 16172-2026 and ISO 5660-1, delivering repeatable results with minimal manual intervention.
Product Highlights:
High-Uniformity Radiant Cone Heater: Equipped with a 5000W imported heating tube, providing adjustable radiant heat flux from 0–100 kW/m² with center deviation ≤ ±2%. This ensures consistent thermal radiation across every test specimen.
Thermally Isolated Precision Weighing: A double thermal barrier design protects the 0.1g precision weighing sensor from high-temperature radiation, ensuring stable mass loss tracking over hundreds of hours of testing.
Fully Automated Workflow: Features an automatic radiation shield and computer-controlled ignition monitoring. Once the test starts, the system handles gas sampling, smoke analysis, and data logging automatically.
Integrated Gas & Smoke Analysis: Built-in drying and filtering modules coupled with real-time CO/CO₂ and smoke density sensors evaluate secondary fire hazards from toxic fumes.
Dual Control System: Combines a 7-inch touch screen for on-site operation with PC software for real-time HRR curve plotting and one-click report generation for certification filings.
Global Standards Compliance for International Markets
Whether you are serving the European and American rail vehicle market or material manufacturers in the shipping sector, the ZXLR is a versatile investment that maps onto a wide set of global standards:
- ISO 5660-1 & 5660-2 (Heat and smoke release)
- ASTM E1354 (Oxygen consumption calorimeter)
- BS 6873 (Railway vehicle fire test)
- IMO International Maritime Organization fire safety test specifications
- GB/T 16172-2026 (National standard for building materials)
FAQ
What is the “oxygen consumption method” in fire testing? It is the principle used by cone calorimeters to calculate heat release by measuring how much oxygen is consumed from the air during the combustion of a specimen, generally accepted as 13.1 MJ of heat released per 1 kg of oxygen consumed.
Which materials can the ZXLR Cone Calorimeter test? It is ideal for plastics, rail vehicle seat structures, metal/rubber components, textiles, upholstered furniture, and all surface materials required for building fire simulations.
Why is FIGRA and SMOGRA important? These indices, calculated during cone calorimeter and SBI tests, track the speed of fire growth and smoke production, respectively. They are critical for determining the fire hazard grade of materials used in public spaces.
What power supply does the equipment require? The system typically runs on AC 220V 50Hz/60Hz with a rated power of 5kW to support the radiant cone heater.
