Test procedure and report - E-12

Set up, implement and use a test

A. Scope

This document is used to prepare, implement and use the results of tests on a given product.

It should be noted that a test report may be the compilation of the documents from Test Readiness Review (TRR) minutes + as runs + Test Review Board (TRB) minutes.

B. Fundamentals

The purpose of a test on a product is to find out or check the performance and behaviour of the product, as set out in the specification or test request (refer to E 2).

The three types of tests concerned are:

  • Adjustment tests:


These are the first experimental justifications of the Definition File.

  • Qualification tests:


The purpose of these tests is to demonstrate that a product has been manufactured according to the definition file and that it meets the requirements of the Specification of Requirement (STB) (resistance to environments, performance) with the requisite margins.

The test plan shall be established in coherence with the Verification matrix defined for the product.

  • Acceptance tests:


These shall demonstrate the conformity of the product manufacturing with respect to the characteristics described in the Definition File. In this case, the test procedure is called the "acceptance procedure".

Every test shall be defined by a Test Request (TR), planned in the Assembly, Integration and Test Plan (AITP) and the Events Log, and carried out according to written and validated procedures.

The test procedures shall be established by the person who performs the test (Assembly, Integration and Test (AIT) activity managers - electrical, mechanical, etc. specialists) and shall be validated by the Technical Manager of the project concerned and by the Quality Assurance (QA) Manager before the tests are started.

A Test Readiness Review (TRR) (see PA 15) shall precede the tests. It shall make it possible to verify the configuration and the preparation status for running the tests (facilities, procedures, etc.).

The Test Review Board (TRB) (see PA-16) shall be convened at the end of the tests, and shall enable a decision to be made concerning the implementation of the tests and the conformity of the results, in view of the test report sent for analysis/validation to the architects and instrument managers prior to holding the TRB.

The procedure for processing anomalies shall be applicable throughout the duration of the tests.

C. Typical content

1. Scope

This section shall contain all the information concerning purpose and scope, such as:

  • The model, system, subsystem, (etc.),
  • The type of test carried out (qualification, acceptance, adjustment, calibration, etc.).



This document defines the acceptance procedure carried out on the Sensor Unit of the "R2D2" project


  • The development level of the piece of equipment to be tested (mock-up, prototype).



The tests shall be carried out on the flight model of the Sensor Unit of the "R2D2" project


  • The facilities and activities concerned, and the personnel or services involved,
