Typical acceptable vacuum furnace leak rate varies with the application of the furnace or the operations to be performed and/or the materials to be heated. A typical size new furnace would be less than 10 microns per hour for a mechanically pumped furnace. A diffusion pumped pumped furnace might be less than 5 microns per hour. These rates are for clean, dry and out-gassed conditions.

If I understand the question, I believe the answer is they are the same. In the vacuum furnace industry, when we say "leak rate", we typically are measuring pressure as it rises to provide an indication of the in leakage of gasses into the vessel or furnace. This rise in pressure is called the "raRead more
If I understand the question, I believe the answer is they are the same. In the vacuum furnace industry, when we say “leak rate”, we typically are measuring pressure as it rises to provide an indication of the in leakage of gasses into the vessel or furnace. This rise in pressure is called the “rate of rise” when referenced over a period of time.
