This document specifies the monitoring of mechanical tests and inspections performed both at the material (coupon) and at the structural scale by the implementation of kinematic field measurements by digital image correlation. This document describes an in situ method for evaluating the metrological performance of an extensometer system using image correlation for the delivery of displacement fields, and by extrapolation, of deformation fields. It can be implemented prior to the actual start of the test (or inspection). It will inform of the metrological performance in testing conditions.
This document allows the metrological performance of the measuring technology to be quantified. The methodology described herein is not to be considered as a calibration step. This reference document does not exhaustively specify the constitutive elements of a generic system of Digital Image Correlation measurement. This reference does not address the measurement of 3D shapes via stereocorrelation systems.

It defines the preferred way to determine the susceptibility of metals and weldments to stress-corrosion cracking by alternate immersion
in 3.5 % sodium chloride under constant load.
The results obtained from test programmes made according to this specification are used to classify alloys, weldments and their individual heat treatment conditions. When sufficient stress-corrosion data exists, the alloy designations can be submitted for inclusion into the
various tables contained in ECSS-Q-ST-70-36.

•   The selection of metal alloys for which preference is given to approved data sources (Table 5 1 to Table 5 3)
•   The criticality analysis to determine if a stress corrosion cracking (SCC) evaluation is necessary
This Standard sets forth the criteria to be used in the selection of materials for spacecraft and associated equipment and facilities so that failure resulting from stress-corrosion is prevented.
It is intended to provide general criteria to be used in stress-corrosion cracking control, which begins during design thanks to a methodological material selection.
This document does not intend to include all factors and criteria necessary for the total control of stress­corrosion cracking in all alloys.
The criteria established in this Standard are only applicable to designs for service involving exposure conditions similar to testing conditions
As regards weldments, this Standard is applicable to aluminium alloys, selected stainless steels in the 300 series and alloys listed in Table 5 1.
This Standard is not applicable to listed materials whose behaviour differs at elevated temperature and in specific chemical.

This Standard defines a multi­test procedure for the determination of the flammability characteristics of non­metallic materials under a set of closely controlled conditions. The test procedure covers both individual materials and materials used in configuration. This Standard describes a series of tests to provide data for aid in the evaluation of the suitability of materials for use in a space vehicle crew compartment. The data obtained are in respect to the ease of ignition and the flame propagation characteristics of materials.
All non­metallic materials are inherently flammable, the degree to which this is true is dependant on the chemical nature of the material itself and the environment to which the material is exposed. In the closed environment of a manned spacecraft this can lead to a potentially dangerous situation and close control is therefore required.

This Standard describes a thermal vacuum test to determine the outgassing screening properties of materials proposed for use in the fabrication of spacecraft and associated equipment, for vacuum facilities used for flight hardware tests and for certain launcher hardware.
This Standard covers the following:
• critical design parameters of the test system;
• critical test parameters such as temperature, time, pressure;
• material sample preparation;
• conditioning parameters for samples and collector plates;
• presentation of the test data;
• acceptance criteria;
• certification of test systems and their operators by audits and round robin tests.
The test described in this Standard is applicable for all unmanned spacecraft, launchers, payloads, experiments. The test is also valid for external hardware of inhabited space systems and for hardware to be used in terrestrial vacuum test facilities.
The outgassing and condensation acceptance criteria for a material depend upon the application and location of the material and can be more severe than the standard requirements as given in clause 5.5.3.1.

Materials used in space applications need to be evaluated for their behaviour under Particle and UV Radiation. As part of this evaluation often an exposure to a simulated space environment is performed that can raise questions regarding its accuracy and representativeness. The role of this Standard is to establish a baseline for the testing specification. NOTE The environments covered are electromagnetic radiation and charged particles. This Standard defines the procedures for electromagnetic radiation and charged particles testing of spacecraft materials. These materials include for instance thermal control materials, windows, coatings, and structural materials. The procedures include simulation of the environment and the properties to be verified.

- contain recommendations for welding and brazing,
- indicate a degree of weldability or brazeability for a given process under defined conditions,
- indicate a value for the welded joint mechanical resistance coefficient for each welding process when
extracted from relevant bibliographical references. Joint coefficient is the ratio of stress resistance
transversally to welded joint over tensile strength of parent alloy.
It recommends ISO/TR 17671-3 and EN 1011-3 for pre-heating conditions specially for the welding of
martensitic steels. These conditions depend on the line energy of welding, thickness, arc welding process and
of hydrogen rate in filler metal.
