Building Materials Flame Retardant Test ISO 5660 ASTM E 1354 Cone Calorimeter

ISO 5660 Cone Calorimeter Product introduction:

Heat release rate is a key performance indicator for evaluating the fire hazard of materials and products. As an internationally used test equipment, the cone calorimeter fully complies with the current major fire test standards and specifications (including ISO 5660 series, ASTM E1354, ASTM E1474, ASTM E1740, ASTM F1550, ASTM D6113, NFPA 264, CAN/ULC-S135 and BS 476-15, etc.). Its test principle is based on the basic thermochemical law of oxygen consumption method: there is a quantitative relationship between the heat released by material combustion and the oxygen consumption, and each kilogram of oxygen consumed corresponds to the release of approximately 13.1 megajoules of heat. During the test, the instrument accurately monitors a number of key parameters: real-time heat release rate, ignition time, oxygen concentration changes, carbon monoxide and carbon dioxide production rates, smoke generation and exhaust flow, etc. These data together constitute a complete evaluation system for the combustion characteristics of the material.

ISO 5660 Cone Calorimeter Test Standards:

• ISO 5660: Tests for reaction to fire - heat release rate, smoke generation rate and mass loss rate
• ASTM E 1354: Standard test method for heat and visible smoke release rate of materials
• BS 476 Pt.15: Testing of building materials and building structures: – Methods for testing the heat release rate of products
• GB/T 16172-2007 Test method for heat release rate of building materials
• NFPA 264

ISO 5660 Cone Calorimeter Structure Feature:

1. 19-inch standard cabinet integrated design, beautiful and easy to operate
2. Conical heater - in a truncated cone, 230V, 5000W, heat output is 0~120 kW/m2
3. 19" touch screen computer controls the entire test process
4. Automatic ignition system, automatic measurement of burning time
5. 3 K-type thermocouples and 3-phase PID temperature controller to regulate temperature
6. Automatic split gate - protect the sample area before testing, ensure the stability of initial quality measurement, and the operator can have extra time to perform system inspection before the test starts. For flammable samples, if there is no opening and closing mechanism, it is easy to burn prematurely. This extra time is very important for the operator
7. Sample holder - sample size 100mm x 100mm, thickness not exceeding 50mm;
