ASTM E1474 Cone Calorimeter Building Materials Fire Testing
Equipment Description: - The Cone Calorimeter is the most significant bench scale instrument in the field of fire testing.
- Heat release is the key measurement required to assess the fire development of materials and products.
- This is based on the empirical observation that heat released by burning materials is directly proportional to the quantity of oxygen used in the combustion process. The instrument was called a Cone Calorimeter.
- This name was derived from the shape of the truncated conical heater that is used to irradiate the test specimen with fluxes up to 100 kW/m2 in the test. Standards: ISO 5660 : Reaction-to-fire tests -- Heat release, smoke production
and mass loss rate. ASTM E1354 : Standard Test Method for Heat and Visible Smoke
Release Rates for Materials and Products Using an Oxygen
Consumption Calorimeter. BS 476: PART 15: Fire tests on building materials and structures..
Part 15: Method for measuring the rate of heat release of products. ASTM E1474 ASTM F1550 ASTM D6113 A full system consists of: 1. Conical Heater - is wound in the form of a truncated cone, rated
5000 W at 230 V with a heat output of 100 kW/m2. 2. Facility for testing horizontally or vertically orientated specimens 3. Temperature control by the use of a 3 type K thermocouples and a 3-term (PID) temperature controller. 5. Specimen Holders - for specimens 100mm x 100mm up to 50mm thick, in the horizontal and vertical orientation. 6. Spark Ignition - by 10 kV spark generator fitted with a safety cut-out device. 7. Exhaust System - hood, gas sampling ring probe, exhaust fan (with adjustable flow controls from 0-50g/s, at a resolution of at least 0.1g/s) and an orifice plate flow measurement (thermocouple and differential pressure transducer). Normal operation is at a nominal 24 l/s. 8. Oxygen Analysis - paramagnetic oxygen analyser, which has a range of 0-25% and a performance compliant with the standards. 9. Smoke Obscuration - measured with a laser system, using photodiodes, and a 0.5 mW Helium Neon laser, with main and reference (compensating) photo detectors. Supplied with alignment cradle and 0.3, 0.8 neutral density filters for calibration. 10. Heat Flux Meter - for setting the irradiance level at the surface of the specimens. 11. Calibration Burner - to calibrate the rate of heat release measured by the apparatus using methane of 99.5% purity. Welcome to visit our factory for sightseeing!
