ECSS-E-10-02A Verification (17 November 1998)

This Standard has been cancelled and replaced by ECSS-E-ST-10-02C (6 March 2009).


This standard establishes the requirements for the verification of a space system product.

It specifies the fundamental concepts of the verification process, the criteria for defining the verification strategy and the rules for the implementation of the verification programme.

It includes also in annex A and B the description of the required documentation (i.e. DRDs) and some guidelines on specific aspects of the verification process such as the Model Philosophy definition.

This standard is intended to apply to different products at different levels (i.e. from a single equipment to the overall system). It is applicable to both the customer and the supplier of the product during all project phases.

The application of these requirements to a particular project is intended to result in an effective product verification and consequently to a high confidence in achieving successful product operations for the intended use.

The requirements of this standard may be tailored for each specific space application, in line with the general ECSS tailoring guidelines (ref. ECSS-M-00-02) taking into account also specific guidelines described in annex B.2.

In preparing this standard the following goals have been considered to facilitate its application, effective use and tailoring:

  • definition of an envelope of the sets of minimum verification requirements applicable to the different products, so that tailoring is a selection (in reduction) process;
  • clear identification of mandatory requirements, tailorable requirements and recommendations by means of the appropriate use of “shall”, “should”, and “may” respectively;
  • text defining requirements shall be self-standing to the greatest possible extent, to allow direct tailoring.
