Heat Release Rate and Smoke Production Testing
The heat release rate (HRR) and smoke production testing are critical components of fire safety evaluation, especially in the context of building materials, furniture, textiles, and other combustible products. These tests are designed to assess how quickly a material will ignite and produce heat, as well as the amount of smoke generated during combustion.
This type of testing is essential for ensuring compliance with national and international fire safety regulations such as ISO 5630-1:2017, ASTM E648-21, and EN 13823. The tests are conducted in a standard environment where the specimen material is subjected to a controlled heat source until it ignites. The rate at which the sample releases heat energy (measured in kW) is recorded as the HRR. Simultaneously, smoke production is measured using optical sensors that detect the light scatter caused by particulates.
The results of these tests are used to classify materials according to their fire hazard potential. This information is crucial for specifying appropriate fire protection measures and selecting suitable products for use in environments where fires could pose a significant risk, such as public buildings, offices, and homes.
In the context of fire safety testing, understanding the behavior of a material under controlled combustion conditions helps to predict its potential contribution to fire growth. This is particularly important for materials that may be used extensively in interior design or construction. By conducting HRR and smoke production tests, we can identify the most hazardous materials and recommend safer alternatives.

Applied Standards
The tests we conduct adhere to several international standards that ensure accuracy and consistency. These include:
- ISO 5630-1:2017 - This standard provides a method for determining the heat release rate of materials.
- ASTM E648-21 - It specifies test methods to determine the heat release and smoke production rates of building products under fire exposure conditions.
- EN 13823 - This European standard outlines procedures for determining the heat release rate and smoke production of materials.
These standards provide a framework that ensures our testing is conducted in a manner consistent with industry best practices, thereby enhancing confidence in the results obtained.
Quality and Reliability Assurance
To ensure high-quality test results, we employ rigorous quality control measures. These include:
- Regular calibration of all test equipment to manufacturer specifications.
- Training of all personnel in the latest testing methodologies and best practices.
- Conducting internal audits at regular intervals to verify adherence to standards.
- Performing duplicate tests on a subset of samples to check for consistency.
We also maintain detailed records of all test procedures, results, and equipment calibration. This documentation is essential for demonstrating compliance with regulatory requirements and for traceability purposes.
