The JPL chamber certification process for ensuring that test chambers used to test flight hardware meet a minimum standard is critical to the safety of the hardware and personnel. Past history as demonstrated that this process is important due to the catastrophic incidents that could occur if the chamber is not set up correctly. Environmental testing is one of the last phases in the development of a subsystem, and it typically occurs just before integration of flight hardware into the fully assembled flight system. A seemingly insignificant -miscalculation or missed step can necessitate rebuilding or replacing a subsystem due to over-testing or damage from the test chamber. Conversely, under-testing might fail to detect weaknesses that might cause failure when the hardware is in service. This paper describes the process that identifies the many variables that comprise the testing scenario and screening of as built chambers, the training of qualified operators, and a general "what-to-look-for" in minimum standards.
