1. The standard time-temperature curve for cellulosic products (ISO 834)
It is a "controlled and ventilated natural fire" model. (e.g. normal building fires)
The curve based on the ISO standard is used in standards around the world including BS 476, AS1530, DIN4102, ASTM
and the European standard BS EN 1363-1
2. Hydrocarbon Curve
This is a "ventilated oil fire" model with a temperature increase of 1110°C after 30 minutes.
The hydrocarbon curve is applicable where oil fires may occur. (for example, gasoline or oil tank, certain types of chemicals, etc.
types of chemicals, etc.)
3. RABT Curve
These RABT curves were developed in Germany following a series of test programs such as the Eureka project
the Eureka project.
In the RABT curve, the temperature rises to 1200°C in 5 minutes. (e.g. cars)
4. RWS Curve
Based on an oil fire of 300MW heat load in an enclosed space such as a tunnel.
5. The HCM curve and other specific curves depend on given test criteria.
