Why Non-Combustibility Testing Matters for Building Products

Building products used in walls, roofs, floors, and other construction applications can have different reactions to fire. A non-combustibility test helps laboratories examine how a material behaves when exposed to a controlled high-temperature furnace environment.

For manufacturers, this type of fire reaction testing can support:

• Building material research and development
• Fire-performance comparison between formulations
• Incoming material inspection
• Production quality control
• Product classification preparation
• Laboratory testing and technical documentation
• Evaluation of homogeneous and non-homogeneous building products

The JBR20 Building Material Non-Combustibility Tester is designed to make this evaluation more controlled and more efficient by combining a high-temperature furnace, Type K thermocouples, computer-controlled operation, automatic timing, and test-result management.

Key Features of the JBR20 Non-Combustibility Tester

Designed for Building Material Non-Combustibility Testing

The JBR20 is purpose-built for non-combustibility tests of building products and their substantial components. Its design supports testing procedures associated with ISO 1182:2020 and the building-material standards listed in the product documentation.

The system can be used by building-material manufacturers, fire-testing laboratories, construction-material research centers, and quality-control departments that require a dedicated non-combustibility test apparatus.

Wide Heating Temperature Range up to 1000°C

The JBR20 provides a heating temperature range from ambient temperature to 1000°C, with a furnace power range of 0–1500 W and a heating voltage range of 0–100 V. This configuration supports controlled heating conditions for high-temperature building material fire testing.

Four-Thermocouple Temperature Measurement

The apparatus is equipped with four Type K thermocouples:

• Two furnace-temperature thermocouples
• One specimen-surface thermocouple
• One specimen-center thermocouple

The thermocouples use a 0.3 mm wire diameter, 1.5 mm outer diameter, and Class 1 accuracy. This multi-point arrangement provides temperature information from the furnace and specimen, supporting more complete observation of the test condition.

The stated temperature measurement accuracy is Class 1, with an accuracy of ±1.5°C or 0.4% of the measured temperature, whichever is greater.

Computer-Controlled Testing and Automatic Data Management

Computer-controlled operation enables high-frequency data sampling, fast system response, and automated data calculation. The JBR20 can automatically determine flame duration, eliminating the need for manual timing and helping prevent missed events during testing.

After testing, results are recorded automatically and can be queried and exported. This function helps laboratories organize test records, review material performance, and prepare internal quality-control documentation.

RS-485 Communication and Interference Resistance

The JBR20 uses a controller with RS-485 communication. The product documentation identifies strong interference immunity as one of the controller’s features, supporting stable communication between the control system and the testing equipment in laboratory environments.

All-Stainless-Steel Furnace Body

The furnace body is made of stainless steel. This design provides resistance to rust, corrosion, and high temperatures while giving the equipment a clean appearance for laboratory and industrial use.

Accurate Specimen Positioning

A height-positioning block is supplied as standard. It enables accurate and rapid positioning of the specimen holder’s lowering height, helping improve the consistency of specimen placement during non-combustibility testing.

Auxiliary thermocouples for specimen-center and specimen-surface measurements are also available according to the product documentation.

Continuous Testing Capability

The JBR20 supports continuous testing of multiple specimen sets. This feature can reduce reheating wait time between tests and improve laboratory throughput when repeated material evaluations are required.

For laboratories conducting comparative fire-performance testing, continuous operation can help increase equipment utilization and shorten the time between test batches.

Rapid Heating and Precise Temperature Control

The apparatus typically reaches a constant-temperature condition within 40–50 minutes and is then ready for testing. The stated temperature stabilization time from ambient temperature to stable operation at 750°C is 40–60 minutes.

The temperature-control algorithm has been optimized through multiple iterations and improved based on a British non-combustibility test furnace. The system can switch from constant-temperature mode to constant-power mode without manual intervention, making the test operation more convenient.

Dual-Loop Temperature and Power Control

The JBR20 uses dual-loop temperature and power control to improve voltage adaptability. During constant-power operation, power fluctuation is less than 1%, while the temperature deviation during empty-furnace operation is less than 2°C, according to the product documentation.

A power-compensation function automatically adjusts heating power when the mains voltage deviates. The soft-start function allows the software to control the heating rate automatically and regulate furnace temperature in stages, which can help extend the service life of the furnace core.

A More Efficient Workflow for Material Fire-Performance Evaluation

The JBR20 combines hardware control and software functions in a single testing workflow:

1. Prepare the specimen according to the applicable test standard.
2. Condition the specimen in the required laboratory environment.
3. Position the specimen holder using the standard height-positioning block.
4. Heat the furnace and allow the system to reach stable operating conditions.
5. Monitor furnace and specimen temperatures using the four thermocouples.
6. Use computer-controlled sampling, automatic flame-duration determination, and data calculation.
7. Record, query, and export the test results for quality control and technical review.

This integrated process helps reduce manual timing, supports repeatable specimen positioning, and provides organized records for product development and building-material fire testing.
