ISO 5660-1 Heat Release Rate Measurement
The ISO 5660 series of standards addresses the fire resistance and flammability testing of building materials. Specifically, ISO 5660-1:2018 focuses on the measurement of heat release rate (HRR) for building products under controlled laboratory conditions.
The HRR is a critical parameter in assessing the fire performance of construction materials and components. It provides valuable information about the amount of heat released by a material during combustion, which can influence the behavior of a fire within a structure. Understanding this parameter helps architects, engineers, and building contractors to select appropriate materials that contribute to safer buildings.
The test is conducted using a cone calorimeter, where the specimen is exposed to radiant heat from an electrically heated hemispherical source (cone) in a controlled environment. The cone provides a specified flux of radiation onto the sample, simulating real-world fire conditions. The HRR is measured by monitoring the increase in oxygen concentration within the combustion chamber.
The procedure involves several steps:
- Preparation and conditioning of the specimen
- Setting up the test rig with the cone calorimeter
- Heating the specimen to a specified temperature
- Monitoring HRR, mass loss rate (MLR), and smoke production rate (SPR)
- Data analysis and reporting
The results of this testing are crucial for compliance with fire safety codes such as NFPA 251 in the United States or EN 13823 in Europe. It also aids in the development of new materials that meet stringent fire performance requirements.
Scope and Methodology
| Step | Description |
|---|---|
| 1. Specimen Preparation | The specimen should be representative of the material to be tested, with dimensions specified by the standard. |
| 2. Conditioning | The specimen must be conditioned in a controlled environment for at least 48 hours before testing. |
| 3. Rig Setup | The cone calorimeter is set up according to ISO specifications, with the sample holder positioned correctly and the combustion chamber calibrated. |
| 4. Testing | The specimen is heated by a radiant source, and HRR, MLR, and SPR are recorded over time. |
| 5. Data Analysis | Data from the test rig is analyzed to determine compliance with specified limits for HRR, MLR, and SPR. |

Applied Standards
The ISO 5660 series of standards is widely recognized for its applicability in various sectors. For buildings and infrastructure testing, ISO 5660-1:2018 specifically addresses HRR measurement.
- NFPA 251 (National Fire Protection Association)
- EN 13823 (European Standard for Building Products)
- ASTM E907 (American Society for Testing and Materials)
The use of these standards ensures consistency in testing procedures across different countries, contributing to a harmonized approach to fire safety.
