EN ISO 1182 Non-Combustibility Test Apparatus

Non-Combustibility Test (EN ISO 1182)

The EN ISO 1182 Non-Combustibility Test Apparatus evaluates the combustibility of building materials by placing a specimen in a vertical tube furnace preheated to 750°C. The test observes whether the material sustains flaming and records any temperature rise to determine its non-combustibility performance.

This non-combustibility test furnace is essential for classifying construction products into fire performance categories such as A1 and A2. It helps manufacturers, testing laboratories, and certification bodies assess the fire safety of materials used in walls, ceilings, insulation, and other building applications under standardized high-temperature conditions.

Technical Parameters

Professional Construction & Technical Precision

The EN ISO 1182 Non-Combustibility Test Apparatus features a vertical tube furnace designed to maintain a stable temperature of 750°C. The furnace construction, combined with precise thermocouple placement, ensures accurate monitoring of both the furnace environment and the specimen temperature throughout the test.

The equipment includes a standardized specimen holder and a stable power supply system with voltage regulation. These features help laboratories achieve consistent and repeatable test conditions, which are critical for reliable non-combustibility evaluation of building materials.

Testing Principle

In the EN ISO 1182 test, a specimen is placed into a vertical tube furnace preheated to 750°C. The test observes whether the material exhibits sustained flaming and records any temperature rise above the furnace temperature using thermocouples. Materials that do not sustain flaming and show limited temperature rise are classified as non-combustible.

This method provides a standardized way to assess the inherent combustibility of building materials, independent of their thickness or density.

Common Error Mitigation

To obtain accurate and consistent non-combustibility test results, the following practices are recommended:

• Ensure the furnace reaches and maintains a stable temperature of 750°C before inserting the specimen.
• Use properly prepared and conditioned specimens according to the standard requirements.
• Correctly position the thermocouples to accurately monitor both furnace and specimen temperatures.
• Avoid drafts or airflow disturbances around the furnace during testing.
• Regularly calibrate the temperature measurement system and timer to maintain accuracy.

Applications & Use Cases

The EN ISO 1182 Non-Combustibility Test Apparatus helps building material manufacturers and testing laboratories determine the non-combustibility of construction products. It supports fire safety classification, product development, and regulatory compliance for materials used in walls, ceilings, insulation, and other building applications.

• Building material manufacturers — Conducting non-combustibility testing of construction products such as insulation, wall panels, and ceiling boards to support A1 and A2 fire classification in accordance with EN ISO 1182.
• Testing laboratories — Performing EN ISO 1182 compliance testing and issuing formal reports on the non-combustibility performance of building materials under 750°C furnace conditions.
• Certification bodies — Assessing and verifying the non-combustibility of building materials as part of A1 and A2 fire classification, supporting regulatory approval for construction products.
• Research institutions and material developers — Studying the combustion behavior of new building materials, composites, and coatings under the standardized 750°C conditions of the EN ISO 1182 vertical tube furnace.
• Quality control departments — Carrying out routine non-combustibility verification during production to ensure batch consistency and maintain compliance with fire performance requirements.
