The advanced technical data collected from home and abroad have properly been analyzed, so that they are useful to improve the photoelectric sensitivity tester. The results of this study have quickly been supplied to the related industry. Our research and development team has verified the response characteristics of the light-emitting and -receiving part of the photoelectric sensitivity tester in order to help the local manufacturer to study, develope and produce their photoelectric detectors.

In this study we compared corrosion resistance tests which were carried out according to the national technique standard and the UL standard to ensure the reliability of smoke detectors in foul weather. The sensitivity of smoke detectors became so blunt that the least operational smoke concentration was a maximum change of 13% in the national technique standard, while it was a maximum change of 145% in the UL standard. As a result of this study the test method of corrosion resistance was made an objective evaluation in the national technique standard. Therefore it could be said that a basis of developing the test method of corrosion resistance was prepared for our country.

In this work wood crib burning behaviors have been simulated by using the FDS(Fire Dynamic Simulator) program. Wood cribs are regularly stacked arrays of wood sticks, and available for the performance rating of fire-extinguishers. On the basis of an angle iron supporter 26 layers of wood sticks have been stacked up. Each layer consists of 5 or 6 wood sticks which are placed in parallel, with a constant distance, and in alternating rows. They are laid between the horizontally adjacent sticks at the before last layer. The wood crib is ignited instantaneously by an amount of burning gasoline below. A comprehensive simulation of such a practical sophisticated combustion is still too difficult to realize with any currently available computer, although the performance of modern processors is getting better everyday. We could carry it out here through parallel computing on the HPC(High Performance Computing) cluster as the feasible alternative. At last the validation has been executed by means of temperature distribution data measured by the thermal video camera.

A standard fire extinguishing tester, with which we could conduct the fire extinguishing ability rating of a water-based fire extinguishing agent such as water and loaded stream, has been developed in this work. It could help us enhancing the efficiency and reliability of the fire extinguishing test of loaded streams, and at last increasing the productivity of fire protection related firms. Furthermore, our country could take the lead in making a new standard for the fire extinguishing test of loaded streams. As a result, it is expected that loaded streams could be improved by using it. In addition the standard fire extinguishing tester could be made moderately in our industry, and supplied at home and worldwide.
