European Foreword
This document (CEN/TR 17602-30-08:2021) has been prepared by Technical Committee CEN/CLC/JTC 5
“Space”, the secretariat of which is held by DIN.
It is highlighted that this technical report does not contain any requirement but only collection of data
or descriptions and guidelines about how to organize and perform the work in support of EN 16602-30.
This Technical report (CEN/TR 17602-30-08:2021) originates from ECSS-Q-HB-30-08A.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
This document has been developed to cover specifically space systems and has therefore precedence
over any TR covering the same scope but with a wider domain of applicability (e.g.: aerospace).
Scope
This handbook identifies data sources and respective methods that can be used for reliability prediction
of components. It proposes suitable data sources and an application matrix for component families.

Selection of reliability data and methods
4.1 Introduction
This handbook can be used whenever EEE and mechanical components reliability data or failure rates
are needed to perform quantitative dependability or safety analyses in accordance with ECSS-Q-ST-30
or ECSS-Q-ST-40.
The boundaries of this process are shown in Figure 4-1. Inputs are project requirements, handbook data
and manufacturer or user data. The selection process should consider selection criteria and methods of
use of data. Outputs are usually included in equipment reliability assessments. Selection is supported
by suitable justification.

4.2 Selection process
The selection of a suitable methodology is made according to Figure 4-2. Where the customer requires
that a reliability prediction be computed according to a particular methodology, contractual
requirements are applicable.
The term “methodology” includes the process, data and equations as defined in a particular handbook
or prediction system.

Figure 4-2: Selection process
In the case where there is no prescribed methodology, this handbook should be applied and a suitable
methodology should be selected.
In the case where the prescribed methodology does not adequately address the component under
consideration, this handbook should be applied and a suitable methodology should be selected.
In order to perform any reliability predictions, reliability data is needed as an input, and a suitable
methodology needs to be applied.
Figure 3 shows the decision logic that should be applied when selecting data sources. Data should be
obtained from the following sources, in order of preference:
• Handbook data
• Manufacturer or user data.

Figure 4-3: Decision logic
A description of data sources is given in clause 4.3.
The choice of a given data source is acceptable if it satisfies the criteria listed in clause 4.4. Data on the
handbook methodology, the components, environment and use should be collected. A suitable
methodology can be selected by using a weighted score ranking scheme, as described in clause 4.4.1.
The rationale for selection is justified according to clause 4.5.
A suitable methodology or instructions for use is described in clause 4.6.
If a handbook is determined to be not suitable for the component, then manufacturer or user data should
be used.
