Derating analysis - PA-9
Justify the application of marges on EEE Components
A. Scope
The derating analysis justifies the fact that the stress levels applied to all EEE components do not exceed the limits specified by the following standard:
- RNC-ECSS-Q-ST-30-11 Derating components
B. Principles of preparation
This analysis consists in checking that the derating rules have been observed on each of the components of the product.
For components subjected to stresses that are higher than those defined in the standard, a justified rationale shall be provided with a request for waiver.
Refer to the analysis example:
