Fire duration - Fire extinguisher time

Japanese: 火災継続時間 - かさいけいぞくじかん
Fire duration - Fire extinguisher time

The standard heating temperature curve (Figure 2) shows the average temperature rise in a fire room based on these calculations and experience.
[Fire duration and fire resistance time]
The duration of a fire can be estimated by dividing the amount of combustible material in a room (fire load) by the amount of combustion determined by the size of the opening. Under general conditions, it is said to last 20 to 130 minutes for a fire load of 50 kg/m2 per floor area, and 35 to 200 minutes for a fire load of 100 kg/m2. It is sufficient if the materials can withstand the heat of the fire during this time and meet the conditions in the next section.

*Some of the terms mentioned in "fire duration" are listed below.

…このような計算値と経験に基づき,平均的な火災室の温度上昇を示すものとして,標準加熱温度曲線(図2)がある。
[火災継続時間と耐火時間]
 火災の継続時間は,室内にある可燃物の量(火災荷重)を,開口部の大きさから決まる燃焼量で割ることで推定可能である。一般的な条件では,室床面積当りの火災荷重50kg/m2で20~130分,100kg/m2で35~200分といわれており,この時間の間,部材が火熱に耐え,次項の条件を満たせばよい。…
