May I ask what the acceptable leakage rate for a biconical oven is? Leakage rate and pressure rise rate of vacuum containers
What is the standard for oven leakage rate?
Vacuum leakage rate: ≤40,000 Pa/24 hours. “\"Vacuum leakage rate\" refers to the amount of decrease in the vacuum gauge reading over 24 hours: in a double-cone dryer during operation, once the vacuum pump has achieved extreme vacuum and this condition is maintained for more than 30 minutes, the valve on the vacuum line is closed, and the resulting decrease in the vacuum gauge reading over 24 hours constitutes the \"vacuum leakage rate\".
