| 換氣老化特點 |
| |
| 本機專門針對橡膠、塑膠 及各種絕緣材料之熱老化性做測試,其性能與一般老化爐不同，本機之設計具備有: |
| a. 溫度調節精度。 |
| 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 |
|
| 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) |
|
