b. 溫度分佈均勻。
c. 開門後溫度回昇速率。
d. 試驗槽內之風速及換氣率。
e. 試驗槽內之隔熱密封。
f. 特殊換氣率調整裝置。
g. 依據測試標準:
JIS K-7217, K-7623, K-6301, ASTM D-2436, D-573, UL-746B, IEC-540, BS-6746, 903, ISO/DIS 4577
換氣率測定方法
This method measures the air change rate of the std type oven as follows
N=3590 (X-Y)x2 / VxDx
T
N: number of changes of air per hour
X: Power consumption during air change (W)
Y: Power consumption during no air change (W)
V: total volume of oven (cm3)
D: Density of oven ambient air (g/cm3)
T: Temperature difference inside/outside oven (°C) |
