 Cone Calorimeter

What is ASTM E1354 Cone Calorimeter?

A cone calorimeter is a scientific apparatus utilized to evaluate the combustion behavior of materials in fire conditions.


structure:

A cone calorimeter usually consists of the following parts:


1.Test Chamber: An enclosed space used to accommodate materials and experimental devices to be tested. Test chambers typically have controlled temperature, oxygen concentration, and ventilation rates to simulate different fire conditions.


2.Cone Heater: A specially designed heat source, usually consisting of a standardized combustion cone, used to apply heat to the surface of the material to be tested.


3.Gas Analysis System: used to monitor and record the composition of flue gases produced during the combustion process, including carbon monoxide, carbon dioxide, oxygen and other harmful gases.


4.Heat Release Rate Measurement System (HRR): used to monitor and record the heat released during the combustion process of materials in real time.


Testing process:

1.Preparation: Place the material to be tested on the sample stage in the testing chamber and position the cone burner on the surface of the material.


2.Ignition: Start the cone burner to ignite the material to be tested. During the combustion process, parameters such as heat release rate and smoke production rate will be monitored and recorded.


3.Data collection: Use a gas analysis system and a heat release rate measurement system to collect and analyze data during the experiment.


Test parameters:

Parameters commonly considered in cone calorimeter experiments include:


  • Peak Heat Release Rate (PHRR): The maximum heat release rate generated during the combustion process, which reflects the burning ability of the material.


  • Smoke Production Rate (SPR): The rate of smoke generated during the combustion process, which is of great significance for assessing fire spread and safe evacuation.


  • Smoke Toxicity: The content and toxicity of harmful substances in smoke produced by combustion have an important impact on personnel safety.



The following are detailed technical parameters about Cone Calorimeter





1. Overview:

1.1 This Cone Calorimeter is designed on the basis of the oxygen consumption calculated from the oxygen concentration in the burning product gas stream and the heat release rate during burning of the products. The heat release rate of the material is also the most important parameter in the burning performance of the material. The device can accurately measure the heat release rate during the burning process of the material. It has a beautiful appearance, convenient and accurate testing, and is extremely important for predicting fire hazards and its flame retardant prevention and treatment.


2. Compliant standards:

2.1 Comply with GB/T16172-2007 "Test Method for Heat Release Rate of Building Materials".

2.2 Comply with current domestic and foreign test standards such as ISO 5660-1:2002 and ASTM E1354.


3. The main technical parameters

3.1 Radiation cone power: rated power 5000W. It can provide radiation intensity up to 100kw/㎡ on the sample surface, equipped with three thermocouples to measure temperature.

3.1.1 Radiation cone structure: The electric heating tube is tightly wound into a truncated cone shape and assembled in a double-layer heat-resistant conical sleeve. The inner and outer cone shells are filled with heat-resistant fibers with a nominal thickness of 13mm and a nominal density of 100kg/m³. The radiation intensity is uniform and corresponds to the radiation at the center, and the deviation does not exceed ±2%; the incident heat flow intensity of the conical heater can be selected according to different test requirements.

3.2 Sample mounting frame: It is a square open plate, the upper opening is: (106±1)mm×(106±1)mm, the depth is (25±1)mm, and the thickness of the mounting frame is 50 (2.4±0.15)mm stainless steel plate. It includes a handle for easy insertion and removal, and a mechanism to ensure that the center of the specimen is below the heater and accurately centered with the weighing device. A layer of low-density (nominal thickness 65kg/m3) heat-resistant fiber mat with a thickness of 13mm is placed at the bottom of the mounting frame; the distance between the lower surface of the radiation cone and the top of the sample is adjusted to (25±1) mm, for unstable size material, the distance from the lower surface of the radiation cone is (60 ± 1) mm.

3.3 Positioning frame: a square box made of stainless steel with a thickness of (1.9±0.1)mm, the inner dimension of the square box is (111±1)mm, and the height is (54±1)mm; it is used for the opening of the sample surface is (94.0±0.5)mm×(94.0±0.5)mm.
