Reliability Demonstration Testing

Use for customer acceptance, product release or a reliability evidence gap. A defined statistical basis makes the meaning and limitations of a pass result clear.

The scope is tailored to the available evidence. Useful inputs include:

• Reliability target, mission time and confidence
• Allowed failures and statistical model
• Available samples, stress conditions and test duration

SPACEREL selects a demonstration method appropriate to the requirement and derives sample size or duration. Independence, censoring and any acceleration assumptions are documented. The conclusion is limited to the tested population and justified use conditions.

Deliverables are agreed before work starts and can include:

• Reliability demonstration plan
• Statistical sample-size or duration justification
• Pass/fail evaluation and confidence statement
