This handbook defines methods for process assessment and improvement that may be used to meet the requirements on
process assessment and improvement of the EN16602-80 (equivalent to ECSS-Q-ST-80C) subclause 5.7. These methods constitute a clear and proven w ay of implementing those requirements. Alternative methods can be used provided that they meet the detailed instructions provided in this handbook for recognition of software process assessment schemes and results and process improvement.
This handbook provides a detailed method for the implementation of the requirements of the EN16602-80 for software process assessment and improvement. It also establishes detailed instructions for alternative methods intended to meet the same EN16602-80 requirements.
The process assessment and improvement scheme presented in this handbook is based on and conformant to the ISO/IEC 15504 International Standard. In designing this process assessment and improvement scheme the ISO/IEC 15504 exemplar process assessment model w as adopted and extended to address specific requirements.
The methods provided in this handbook can support organizations in meeting their business goals and in this context they can be tailored to suit their specific needs and requirements. How ever w hen used to claim compliance with relevant requirements in EN16602-80 only the steps and activities explicitly marked as recommended in this handbook may be omitted or modified.

A common language for standards, disclosed to a wide audience and referring only to the operational protocols and to their outcomes, is needed both for a consistent set of standards and the connection with the scientific literature. This glossary will take into account existing glossary of terms used in photocatalysis and photochemistry. Because in photocatalysis numerous properties are difficult to be evaluated, it is strongly recommended in standard norms to avoid reporting properties depending on number of actives sites, the mechanisms of adsorption or kinetic mechanisms of photocatalytic reactions. For the same reason instead of the quantum yield and related quantities it is easier to report the photonic efficiency.
Most of the definitions reported in this document are a sub-set of the IUPAC definitions in photocatalysis and radiocatalysis [1]. Some other definitions, in particular for the photocatalytic rate and reactors are taken from a dedicated work [2]. The use and many technical specifications on the physical values suggested for irradiation conditions in the standards are reported in a separate Technical Specification [3].
The arrangement of entries is alphabetical, and the criterion adopted by the IUPAC has been followed for the typeface used: italicized words in a definition or following it indicate a cross-reference in the Glossary.

This document specifies requirements for a valuation of energy related investments (VALERI). It provides a description on how to gather, calculate, evaluate and document information in order to create solid business cases based on Net Present Value calculations for ERIs. The standard is applicable for the valuation of any kind of energy related investment.
The document focusses mainly on the valuation and documentation of the economical impacts of ERIs. However, non-economical effects (e.g. noise reduction) that may occur through undertaking an investment are considered as well. Thus, qualitative effects (e.g. impact on the environment)– even if they are non-monetisable – are taken into consideration.

This handbook provides recommendations, methods and procedures that can be used for the selection and reuse of existing software in space software systems.
This handbook is applicable to all types of software of a space system, including the space segment, the launch service segment and the ground segment software (including EGSEs) whenever existing software is intended to be reused within them.
This handbook covers the following topics:
• Software reuse approach including guidelines to build the Software Reuse File
• Techniques to support completion of existing software qualification to allow its reuse in a particular project
• Tool qualification
• Risk management aspects of reusing existing software Existing software can be of any type: Purchased (or COTS), Legacy-Software, open-source software, customer-furnished items (CFI's), etc.
NOTE Special emphasis is put on guidance for the reuse of COTS software often available as-is and for which no code and documentation are often available.
Legal and contractual aspects of reuse are in principle out of scope; how ever guidelines to help in determine the
reusability of existing software from a contractual point of view is provided in [ESA/REG/002].
Any organization with the business objective of systematic reuse may need to implement the organizational reuse processes presented in [ISO12207]. These processes w ill support the identification of reusable software products and components within selected reuse domains, their classification, storage and systematic reuse within the projects of that organization, etc. But these processes are out of scope of this handbook as the handbook is centred on the specific project activities to reuse an existing software product, not part of those organizational reuse processes more oriented to ‘design for reuse’ processes.
In addition, this handbook provides guidelines to be used for the selection and analysis of tools for the development, verification and validation of the operational software.

This document establishes definitions and evaluation methods for wheel-rail contact geometry parameters influencing the vehicle running dynamic behaviour:
-   the rolling radius difference between the two wheels of a wheelset (Δr-function) which serves as a basis for all further calculations;
-   the equivalent conicity function from which are derived:
-   a single equivalent conicity value for a specified amplitude which is relevant for the assessment of vehicle running stability on straight track and in very large radius curves according to EN 14363;
-   the nonlinearity parameter which characterizes the shape of this function and is related to the vehicle behaviour particularly in the speed range close to the running stability limit;
-   the rolling radii coefficient which is used to describe the theoretical radial steering capability of a wheelset in a curved track.
Additional information is given about the relationship between the contact angles of the two wheels of a wheelset (Δtanγ-function) and about the roll angle parameter.
NOTE   Out of the presented parameters only those related to the contact angle are relevant for independently rotating wheels of wheel pairs.
Descriptions of possible calculation methods are included in this document. Test case calculations are provided to achieve comparable results and to check the proper implementation of the described algorithms.
To validate alternative methods not described in this document acceptance criteria are given for the equivalent conicity function. This includes reference profiles, profile combinations, tolerances and reference results with tolerance limits.
This document also includes minimum requirements for the measurement of wheel and rail profiles as well as of the parameters needed for the transformation into a common coordinate system of right- and left-hand profiles.
This document does not define limits for the wheel-rail contact geometry parameters and gives no tolerances for the rail profile and the wheel profile to achieve acceptable results.
For the application of this document some general recommendations are given.

The scope of this Handbook is the software metrication as part of a space project, i.e. a space system, a subsystem including hardware and software, or ultimately a software product. It is intended to complement the EN 16602-80 (equivalent to ECSS-Q-ST-80) with specific guidelines related to use of different software metrics including their collection, analysis and reporting. Tailoring guidelines for the software metrication process are also provided to help to meet specific project requirements.
This Handbook provides recommendations, methods and procedures that can be used for the selection and application of appropriate metrics, but it does not include new requirements w ith respect to those provided by EN 16602-80 (equivalent to ECSS-ST-Q-80).
The scope of this Handbook covers the following topics:
• Specification of the goals and objectives for a metrication programme.
• Identification of criteria for selection of metrics in a specific project / environment (goal driven).
• Planning of metrication in the development life cycle.
• Interface of metrication with engineering processes.
• Data collection aspects (including use of tools).
• Approach to the analysis of the collected data.
• Feedback into the process and product based on the analysis results.
• Continuous improvement of measurement process.

This Handbook provides guidance on the application of the dependability and safety requirements relevant to software defined in EN 16602-80 (equivalent of ECSS-Q-ST-80).
This Handbook provides support for the selection and application of software dependability and safety methods and techniques that can be used in the development of software-intensive space systems.
This Handbook covers all of the different kinds of software for which EN 16602-80 (equivalent of ECSS-Q-ST-80) is applicable. Although the overall software dependability and safety workflow description is mainly targeted to the development of spacecraft, the described approach can be adapted to projects of different nature (e.g. launchers, ground systems).
The methods and techniques described in the scope of this Handbook are limited to assessment aspects, not including development and implementation techniques for dependability and safety (e.g. fault tolerance techniques, or development methods like coding standards, etc.).
Although dependability is a composite term, including reliability, availability and maintainability, this Handbook addresses in particular the reliability aspects. Software maintainability and availability are not covered in depth by this handbook, because the relevant methods and techniques are still undergoing improvement. Nevertheless, whenever a link can be made to either of these two characteristics, it is explicitly mentioned in the corresponding section.
