This standard specifies the requirements, also known as “relifing requirements”, for the planned, intentional storage, control, and removal from storage of electronic, electrical and electromechanical parts which are intended to be used for space applications.

This standard covers the relifing of all components as defined by ECSS-Q-ST-60 and ECSS-Q-ST-60-13.

The relifing process is a lot quality control activity.  The inspections and tests defined do not constitute an up-screening or up-grading of components to a higher level of quality than procured to.

In line with ECSS-Q-ST-60, this standard differentiates between classes of components through different sets of standardization requirements.

The classes provide levels of trade-off between assurance and risk. The highest assurance and lowest risk is provided by Class 1 and the lowest assurance and highest risk by Class 3. Procurement costs are typically highest for Class 1 and lowest for Class 3. Mitigation and other engineering measures can decrease the total cost of ownership differences between the three classes. The project objectives, definition and constraints determine which class or classes of components are appropriate to be utilised within the system and subsystems.

Class 1 components are described in Clause 4, 5 and 6

Class 2 components are described in Clause 4, 5 and 6

Class 3 components are described in Clause 4, 5 and 7

The requirements of this document apply to all parties involved at all levels in the integration of EEE components into space segment hardware and launchers.

This standard is applicable to all EEE parts covered by ECSS-Q-ST-60 and used in space programmes.

This standard is not applicable to dice.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

This part of IEC 60794 is a family specification covering optical fibre indoor cables that deployed in short length (≤ 10 m) outdoor environments. These cables generally possess the characteristics associated with indoor cable designs having the appropriate fire performance and flexibility that makes them suitable for use in premises. Because of its predicted use outdoors stability against environmental attack e.g. UV radiation and humidity (see Table 1, IEC 60794-6) is required. Typical application spaces include the extension of a short length of indoor cable outside the building such as to a NAP mounted outside the building at the house wall.

This part of IEC 60794 is a family specification covering optical fibre outdoor cables which are flame retardant and thus also applicable to indoor environments. These cables generally possess the characteristics associated with outdoor cable designs having similar thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously exhibiting the fire performance required in indoor premises. Typical application spaces are: e.g. extension of a “shorter length” of an outdoor cable into the building.

This part of IEC 60794 is a family specification covering features of optical fibre cables applicable to outdoor as well as indoor environments: so called “Universal Indoor-Outdoor cables”. These cables generally possess the characteristics associated with outdoor cable designs (according to IEC 60794-3 however typically less stringent, typically “non armoured”) having the thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously being flexible enough, compact and lightweight and exhibiting the fire performance required in indoor premises.  A typical application is e.g. the centralized cabling in central office, the Premises or Local Area Network where the same cable design is used for the entire length of the cabling link including both the indoor as well as the outdoor portions.

This part of IEC 60794 is a sectional specification covering general features of optical fibre cables applicable to outdoor as well as indoor environments: so called “indoor-outdoor cables”. Indoor-Outdoor cables are deployed in outside plant environment as well as in premises and thus fulfilling outdoor as well as indoor requirements. Typical application spaces are: e.g. extension of a duct cable into a building or using this design for centralized cabling in the central office, the Premises or Local Area Network where the same cable is used for the entire length of the cabling link including both the indoor as well as the outdoor portions.

Cables of which generally possess the characteristics associated with outdoor cable designs having the thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously being relatively flexible, compact and lightweight while exhibiting the fire performance required in indoor premises are specified in IEC 60794-6-10.

Flame Retardant Outdoor cables (see IEC 60794-6-20) are used when most of the cable length is deployed as an outdoor cable with a part of its length is deployed indoors. The cable design can be derived from a typical outdoor cable design according to the product specifications described in IEC 60794-3. The specific demand related to bend radii according to the installation situation and fire performance according to the regional legislation mainly requires the appropriate selection of the jacket material in combination with other material and / or design considerations.

Because of the use in buildings with tighter space restrictions, higher flexibility of the cable is often required for the installation. Often lower diameter cables are to be preferred.

Indoor cables which are weatherised (see IEC 60794-6-30) are used when an indoor cable is to be used outdoors over a short distance (few meters) e.g. when the network access point, NAP, is very close to the building. The indoor-outdoor fibre optical cable design can be derived from an indoor design (see IEC 60794-2 and IEC TR 62901 for typical applications) with specific outdoor performance features added. Critical parameters are UV stability, and resistance against exposure to humidity.

This International Standard series lays down IEC requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The actual lifetime expectancy of modules so qualified will depend on their design, their environment and the conditions under which they are operated.  Test results should not be construed as a quantitative prediction of module lifetime. In climates where 98th percential operating temperatures exceed 70 °C, users may want to consider testing to higher temperature test conditions as described in IEC TS 63126.

This International Standard series lays down IEC requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates. This part of IEC 61215 is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules.

This standard does not apply to modules used with concentrated sunlight although it may be utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests are performed using the current, voltage and power levels expected at the design concentration.

The objective of this test sequence is to determine the electrical and thermal characteristics of the module and to show, as far as possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in general open-air climatesoutdoors. The actual lifetime expectancy of modules so qualified will depend on their design, their environment and the conditions under which they are operated.  Accelerated test conditions are empirically based on those necessary to reproduce selected observed field failures and are applied equally across module types.  Acceleration factors may vary with product design and thus not all degradation mechanisms may manifest. Test results should not be construed as a quantitative prediction of module lifetime.Further general information on accelerated test methods including definitions of terms may be found in IEC 62506.
