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. Traditionally it has been very difficult to measure and more recently full scale testing of items (e.g. furniture) has been possible by burning these articles and measuring the evolved heat using a technique called oxygen depletion calorimetry. The Cone Calorimeter has been produced to meet all existing Standards (including ISO 5660, ASTM E1354, ASTM E1474, ASTM E1740,ASTM F1550, ASTM D6113, CAN ULC 135 and BS 476 Part 15) and can also be purchased in modular form so that those laboratories with particular interests such as heat release, mass loss, smoke production, etc. can initially purchase the sections they require and later add further instrumentation into the same cabinets in order to complete a full specification instrument. This is just one of the advantages of the Cone Calorimeter.
Application:
Combustion product stream through the oxygen concentration of the oxygen consumption and calculate the heat release rate, heat release rate of the material is also the material properties of the combustion products of the combustion burner of the most important parameters, more accurately measure the material during combustion heat release rate, for predicting fire hazard prevention and fire-retardant treatment is extremely important.
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. GB/T 16172-2007: Test method for heat release rate of building materials ASTM E1354 Fire Testing Equipment ISO 5660 Heat Release Rate Cone Calorimeter
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. 4. A Split Shutter Mechanism - protects the sample area before the test. This ensures the initial mass measurement is stable and the operator has additional time for system checks before starting the test. This added time is very important for easily-ignitable samples, which often ignite prematurely if a shutter mechanism is not used. 5. Specimen Holders - for specimens 100mm x 100mm up to 50mm thick, in the horizontal and vertical orientation. 6. Load Cell - mass measurements are conducted via a strain gauge load cell with an accuracy of 0.01g. Fitted with a quick electronic tare facility and mechanical stops to avoid movement damage, give stable results and long life. 7. Spark Ignition - by 10 kV spark generator fitted with a safety cut-out device. The igniter is automatically positioned by a lever linked with the shutter mechanism. 8. Exhaust System - manufactured from stainless steel for long life. This comprises, 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. 9. Gas Sampling - comprising particulate filters, refrigerated cold trap, pump, drying columns and flow control. 10. Oxygen Analysis - paramagnetic oxygen analyser, which has a range of 0-25% and a performance compliant with the standards. 11. 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. 12. Heat Flux Meter - for setting the irradiance level at the surface of the specimens. 13. Calibration Burner - to calibrate the rate of heat release measured by the apparatus using methane of 99.5% purity. 14. Data Acquisition – Agilent Data Acquisition / Switch Unit featuring a 3-slot cardcage with 6½ digit (22 bit) internal DMM enabling up to 120 single-ended or 48 double-ended measurements. Scan rates up to 250 channels/s are available with a 115kbaud RS232 and PCI GPIB interface as standard. All readings are automatically time stamped and can be stored in a non-volatile 50,000-reading memory. 15. ConeCalc Software – it is available in multi-languages including English, French, German, Spanish and Japanese. The user interface is a Microsoft Windows based system with “user friendly” push button actions and standard Windows data entry fields,drop down selectors, check boxes and switches capable of:- Showing the status of the instrument Calibrating the instrument and storage of calibration results Collecting data generated during a test Calculating the required parameters Presenting the results in a manner approved by the Standards Averaging of multiple tests Exporting data into FDMS (Fire Data Management System) - a format used by major European and US labs for sharing data between labs with different calorimeters. Exporting file for CSV (comma separated variable) files for quick transfer to spreadsheets.
