１．研究の背景および目的
As high rise building acts as the landmark function with urban symbol, it has an advantage maximizing
land use. For this high rise building, various exterior materials are used for the external aesthetics andin particular, energy saving function is focused on. Therefore, it has been increased to use noncombustible materials. As shown in the cases for fire accidents of exterior materials, fire of high risebuilding leads to a lot of damages for human as well as asset. Although there is an international test
method to evaluate fire safety on exterior materials, there is no experience that the comparison tests
are carried out among counties. Therefore, evaluation on the applicability has not been enough carriedout. Thus, evaluation test for fire safety performance using Façade Test Facility which is owned only
by TUS is carried out in the study and then it is to be compared with the Korean test result andanalyzed.

３．実験方法・研究成果、および考察（申請時の計画に対する達成度合いも含む）※継続課題の場合は，前年度との関係性，進展度合いについても記載すること。

In JFY 2014, the following items were planned as the first year trial.
1.

To make the correlative analysis of the Façade test method between Korean and Japan2.

To make the calibration test by gas burner and wooden crib by ISO 13785-2

3.

To compare the calibration results in terms of heat flux meter and thermocouple

4.

To report test results

For fulfilling the above plan in JFY 2014,
Façade tests based on ISO 13785-2 were successfully conducted in TUS by the calibration method of gasburner and wooden crib. The results from heat flux meter and thermocouple were obtained and comparedwith the preliminary test results which were performed in TUS. For analyzing a series of heat flux andtemperature from calibrating, Collaborators(Mr. Kye-Won Park, Dr. Yoshihiko Hayashi), Head(Dr. HidekiYoshioka) of Japanese delegation in ISO TC92 SC1, and Prof. Yoshifumi Ohmiya have made the technicalmeeting so that we were able to focus on the meaningful issues on pursuing the reasonable calibration
progress.

Furthermore, for the purpose of the precise comparison of Japan’s TUS with Korea’s KICT, a series ofcalibration tests are scheduled to conduct in March, 2015. After then, Finally it is considered that the drafton ISO 13785-2’s revision will be proposed to ISO TC92 SC1 WG7 by delegation of Korea and Japan.

Test devices for building exterior materials are owned only by ‘Tokyo University of Science’ in Japan.
Real scale-based research through TUS’s great façade test facility will be a good chance to meet thedemands on fire safety study of exterior safety. In addition, as the result of the internationallycomparing test could be provided as beneficial information to the ISO TC92 SC1, it will be positively
contributed for the purpose of the advance of international standard.

□ Discussion-As the calibration results, TUS measuring values(heat flux and temperature)are higher than KICT.
It is predicted to air supply system and ventilation condition different.

-From experience with ISO 13785-2, it is necessary to clarify some specific items(ig. main andalternative ignition sources, ventilation condition) with the calibration procedure. But there areunclear things for calibrating process for conducting this standard as follows○ Heat-flux meter's specification would be specified :: A range of the heat-flux meter is '(0~100) kW/m2'.
: But it should be extended or modified based on the experimental result of Korea and Japan.
It's not enough.
: And also, the detailed specification of heat-flux should be considered whether it's proper ornot.
○ Ventilation Condition: It should be clarified that the ventilation condition(Height of Hood)○ In Alternative source of Annex: Liquid should be specified concerning the size of pan on heptane and acetone calculationfrom heat of combustion.
: The environment temp. and humidity should be described.
: Wooden cribs: It' impossible to be ignited within 1min. It should be revised as well.
: The calibration process on Alternative sources should be mentioned.

４．今後の展望（今後の発展性，見込み等についても記述）
In JFY 2015, the following items are proposed as the second year work.
1. To simulate the FDS based on ISO 13785-2 configuration in calibration for the purpose ofcomparison with experimental results done in JFY 2014.
2. To conduct small sample by ISO 5660-2 for checking the thermal property of wooden crib andrepeat ISO 13785-2 calibration test for collecting the uncertainty components(ig. Air velocity ofextraction hood, heat of combustion of wood, and etc) so as to make the calibration procedure
more valid.
3. To make comparison on Heat Flux and Temperature results from real scale façade calibration
test using gas burner(TUS and KICT) and FDS Simulation results
4. To apply the liquid fuel described in ISO 13785-2 as an alternative ignition source, and comparethe other calibrating methods’ results.
To reflect the final results into the draft of ISO 13785-2 revision, and propose our draft to the ISO TC92
SC1 WG7 in 2015.
