This Standard specifies the general requirements for the qualification, procurement, storage and delivery of photovoltaic assemblies, solar cell assemblies, bare solar cells, coverglasses and protection diodes suitable for space applications.

This standard does not cover the particular qualification requirements for a specific mission.

This Standard primarily applies to qualification approval for photovoltaic assemblies, solar cell assemblies, bare solar cells, coverglasses and protection diodes, and to the procurement of these items.

This standard is limited to crystaline Silicon and single and multi-junction GaAs solar cells with a thickness of more than 50 mm and does not include thin film solar cell technologies and poly-crystaline solar cells.

This Standard does not cover the concentration technology, and especially the requirements related to the optical components of a concentrator (e.g. reflector and lens) and their verification (e.g. collimated light source).

This Standard does not apply to qualification of the solar array subsystem, solar panels, structure and solar array mechanisms.

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

Qualification is a process to confirm compliance with requirements that have been established with reference to foregoing characterization and engineering test programs. Guidelines for characterization and engineering tests and for relaxation of qualification tests due to similarity with earlier performed qualification are defined in the handbook ECSS-E-HB-20-08. Those clauses in this standard, for which the Handbook gives additional information, will refer to the Handbook.

This document is applicable to the system engineering of bogies and running gear for rail vehicles, including those vehicles intended to operate under the Interoperability Directives.

It specifies the requirements to achieve:

—    a satisfactory design of bogie or running gear

—    validation of the design within its operating envelope

—    a maintenance plan

to ensure the relevant performance and safety criteria are maintained.

The system engineering process addresses only the design, validation and maintenance of bogies and running gear. No requirements are set for other systems components that are attached to the bogies or running gear, except to establish that a satisfactory interface has been provided.

NOTE          Specifications that relate to bogies and running gear can only be considered in the context of a specific vehicle application. Therefore, the performance, including safety, can relate only to the bogies and running gear as part of a vehicle configuration and not to the individual elements of the bogies or running gear.

This document specifies minimum requirements for life rafts carried on helicopters operating in a hostile sea area or over very rough sea conditions. Life rafts covered by this document are for use by helicopter crew members and passengers in the event of a ditching or water impact.

They are intended either for integration into the helicopter, or stowed in the cabin before being manhandled out of the helicopter. This document does not cover air-drop life rafts.

This document is applicable to new manufactured tags after publication of this document.

This document aims to:

—    provide specification for RFID tag manufacturers to design and manufacture passive UHF RFID tags for the aeronautical industry;

—    identify required performances for UHF RFID tags in order to be read/written during ground operations only, while being subject to the global flight environment;

—    identify functional and environmental validation tests to be performed on passive UHF RFID tags with associated pass/fail criteria as well as associated test methods;

—    check functionalities and resistance to environment for airborne passive UHF RFID tags.

This document does not cover:

—    the reader (interrogator – readers). It will be addressed appropriately by individual applicants;

—    active RFID devices or battery assisted passive (BAP) RFID devices;

—    RFID tags designed to operate outside the 860 to 960 MHz frequency range.

The requirements contained in this document apply to the brake pad holders with which the rail vehicles of main-line railways, regional and suburban railways are fitted. Brake pad holders pursuant to this document are to be made from ferrous materials e.g. cast iron, cast steel or forged steel. Brake pad holders made of non-ferrous materials are not subject of this document.
