| Summary: | (type K) thermocouples. A direct relationship between time 12-channel scanning thermometer and 30 AWG chromel-alumel by ASTM D 3874 - 90a - Standard Test Method for Ignition of by ASTM D 3874. Temperature measurements were made using a circuit capable of maintaining a continuous 60 Hz power density of 0.26 W/mm over 12 inches (304.8 mm) of No. 24 AWG, detected this relation no similar study using this procedure electrical equipment. The main objective of this project was expected result, since extensive research has already Ignition Test. This test is prescribed by Underwriters investigated. The apparatus used for this test was specified Laboratories as one of various requirements for polymeric Materials by Hot Wire Sources. It consisted of a supply materials used in enclosures or insulation systems of may be used to obtain important information regarding the Nichrome V wire and a variable transformer for adjustment of of temperature measurements, it is clear that this procedure phenomena of selected polymeric materials using the Hot Wire piece of the wire was calibrated according to procedure given some materials during the ignition process were also The purpose of this research was to investigate the ignition the voltage to achieve the desired current. A representative thermo-physical characteristics of polymeric materials. time. In addition, temperature changes at the surface of to identify the effect of specimen thickness on the ignition to ignition and thickness was verified. Although this was an was found in the literature. Furthermore, from the results |
