Outgassing Testing

The rig is built to NASA and ESA specifications, but is not audited due to the cost of this procedure. However, reference samples are included in the run and the results always agree with published data within 1%.

Other than the provision of twelve, rather than twenty-four specimen compartments, tests are run to ECSS-Q-ST-02C (previously ECSS-Q-70-02A) specifications - 2000 issue.

Twelve cells are available per run. The allocation of these is, of course entirely up to the customer. However we recommend the following allocation:

I.
Eight cells for the test speciment - two samples of each of four specimens (the loading and unloading of the rig is a delicate operation. Accidents are rare, but possible, and duplicate samples are an insurance against these.)

II.
Two cells for known samples

III.
Two empty cells as controls

Although not called for in the ESA specification, we monitor the vacuum with a mass spectrometer and provide the customer with a print-out.
A report of mass loss and gain is produced with annotations where anomalies or unexpected results arise.
The price quoted is for a basic run. Any other requirements - eg. post-run conditioning are priced accordingly.
