Calibration of Fire Resistance Test Furnaces. Nordtest Project No. 785-88

摘要

A method for calibration of fire resistance test furnaces has been developed. The main objectives of the calibration test are to ensure that uniformity of heating over the exposed surface of the test specimen, and a stipulated level of heating exposure are obtained. The performance of the furnace is obtained by comparing the temperature histories of the measuring elements with a temperature reference curve which represents the calculated temperature of a measuring element exposed to 'ideal ISO 834 conditions'. The report describes the proposed calibration method and the calibration equipment.
