NOTE   Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated and made applicable to a specific project, by selection and in some exceptional cases, modification of existing or addition of new requirements.

This Standard is part of a collection of European Space Standards dealing with management. It defines the process of tailoring, applicable to all space standards for management, product assurance and engineering as a guideline. This Standard defines the objectives, principles, methods and processes of tailoring, which are necessary for the establishment of project requirement documents.

This standard is designed to facilitate the elaboration of a management system which is cost effective, appropriate to the project in which it is implemented, compatible with the actor's existing structures and which has the flexibility to adapt to changing needs throughout all the phases of an evolving project, and to new projects.

EN 14607 Part 6 of Space engineering - Mechanical defines the requirements for the discipline of pyrotechnics engineering.
This part defines the standards to be applied for the use of pyrotechnics on all spacecraft and other space products including launch vehicles. It addresses the aspects of design, analysis, verification, manufacturing, operations and safety.
As any pyrotechnic item used for flight can function only once, it can never be fully tested before its crucial mission operation. The required confidence can only be established indirectly by the testing of identical items. Test results and theoretical justification are essential for demonstration of fulfilment of the requirements. The requirement for repeatability shows that product assurance plays a crucial role in support of technical aspects.
The failure or unintentional operation of a pyrotechnic item can be catastrophic for the whole mission and life threatening. Specific requirements can exist for the items associated with it. As all pyrotechnic functions are to be treated similarly, collective control needs to be applied in the manner of a subsystem.
When viewed from the perspective of a specific project context, the requirements defined in this document should be tailored to match the genuine requirements of a particular profile and circumstances of a project.
NOTE   Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated, and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.

ISO 14620-1:2002 defines the safety programme and the technical safety requirements that are implemented in order to comply with the safety policy as defined in ISO 14300-2. It is intended to protect flight and ground personnel, the launch vehicle, associated payloads, ground support equipment, the general public, public and private property, and the environment from hazards associated with space systems. Launch site operations are described by ISO 14620-2.
The safety policy is applied by implementing a system safety programme, supported by risk assessment, which can be summarized as follows: hazardous characteristics (system and environmental hazards) and functions with potentially hazardous failure effects are identified and progressively evaluated by iteratively performing systematic safety analyses; the potential hazardous consequences associated with the system characteristics and functional failures are subjected to a hazard reduction sequence whereby hazards are eliminated from the system design and operations, hazards are minimized, and hazard controls are applied and verified; the risks that remain after the application of a hazard elimination and reduction process are progressively assessed and subjected to risk assessment, in order to show compliance with safety targets, support design trades, identify and rank risk contributors, support apportionment of project resources for risk reduction, assess risk reduction progress, and support the safety and project decision-making process (e.g. waiver approval, residual risk acceptance); the adequacy of the hazard and risk control measures applied are formally verified in order to support safety validation and risk acceptance; safety compliance is assessed by the project and safety approval obtained from the relevant authorities.
ISO 14620-1:2002 is applicable to all space projects where during any project phase there exists the potential for hazards to personnel or the general public, space flight systems, ground support equipment, facilities, public or private property, or the environment.
The imposition of these requirements on the project suppliers' activities requires that the customer's project product assurance and safety organization also respond to these requirements in a manner which is commensurate with the project's safety criticality.
When viewed from the perspective of a specific programme or project context, the requirements defined in ISO 14620-1:2002 should be tailored to match the genuine requirements of a particular profile and circumstances of a programme or project.

These requirements, as tailored in the related project requirements document are applicable to any actor of a space project.

This European Standard contains the definition of all common terms used in European space standards. Terms specific to a particular space standard are defined in that standard.

Several classes of material depend on a chemical reaction for their application and their final properties are sensitive to the exact composition of the reactants. The final properties vary with the reactants’ age and storage condition.
This European Standard specifies the procedure to be used for the control of limited shelf­life materials employed in the fabrication of spacecraft and associated equipment.

This European Standard defines a test procedure for the determination of the release of trace contaminants by non-metallic materials under a set of closely controlled conditions. The test procedure covers both individual materials and assembled articles.
This Standard describes a test to provide data for aid in the evaluation of the suitability of assembled articles and materials for use in a space vehicle crew compartment. The data obtained are in respect of the nature and quantity of organic and inorganic volatile contaminants evolved when subjected to the crew compartment environment.

This European 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.
Three categories of materials are listed in Tables 1, 2 and 3 of this Standard. They represent metal alloys with a high, moderate and low resistance to stress-corrosion cracking.
The stress-corrosion susceptibility of alloys included in this Standard was determined at ambient temperature
-   by means of laboratory tests in which specimens were either sprayed with salt water or periodically immersed and withdrawn;
-   by exposing specimens in sea coast or mild industrial environments;
-   by subjecting fabricated hardware to service conditions.
Use of the criteria established herein should, therefore, be limited to designs for service involving similar exposure conditions.
Weldments present a special problem in designing for resistance to stress-corrosion cracking. In addition to the susceptibility of the parent metals, it is also necessary to consider the filler metal and the microstructural effects of heat introduced by the welding operations and subsequent heat treatments. Because of the additional variables that shall be considered, susceptibility data are not as extensive for weldments as for alloys in mill form. Design criteria for weldments in this Standard are limited to aluminium alloys, selected stainless steels in the 300 series and other specific alloys listed in Table 1.
This Standard is intended to provide general criteria to be used in designing for resistance to stress-corrosion cracking. Specific test data and other detailed information are not included.

This European Standard specifies a multi­test procedure for the determination of the flammability char-acteristics of non­metallic materials under a set of closely controlled conditions. The test procedure cov-ers 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 char-acteristics of materials.

-   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, and 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 acceptance criteria for a material, based upon the outgassing test data, depends upon the application and location of the material and can be more severe than the standard requirements as given in 7.2.

This European Standard details a thermal cycling test under vacuum for the screening of materials and processes intended for use in the fabrication of spacecraft and associated equipment. The test determines the ability of these or other articles to withstand changes of ambient temperature under vacuum.
