All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:
The Vacuum Chamber is empty.
The Vacuum Chamber and other system components are clean and dry.
The System is being operated at Sea Level
The ambient temperature is 18°C +/- 2°C
All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
The specifications are not impacted by the properties of your product.
If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.
It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.

Abbess/Altitude Test Systems allow for items placed under test to be exposed to specific levels of vacuum pressure and even rate of change in order to recreate the conditions of high altitude flight. Integrated thermal vacuum system also enable testing of the temperature extremes experienced. Abbess offers systems in a range of sophistications, from simple manual control to automated systems involving PC/GUI computerized Thermal Vacuum Cycle Controller (TVCC) with customized interface and data logging configurations. Whether simply testing packaging which might experience altitude in shipment or meeting the rigorous test requirements of flight hardware components themselves, Abbess has the ability to match customer requirements with robust, practical and cost effective system solutions.
