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.

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 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.

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 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.

IEC 62056-3-1:2021 is available as IEC 62056-3-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62056-3-1:2021 describes two sets of profiles: the first set of profiles allows a bidirectional communication between a client and a server. This set of profiles is made of three profiles allowing local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported: • base profile: this three-layer profile provides remote communication services; NOTE 1 This first profile was published in IEC 61142:1993 and became known as the Euridis standard. • profile with DLMS: this profile allows using DLMS services as specified in IEC 61334 4 41; NOTE 2 This second profile was published in IEC 62056-31:1999. • profile with DLMS/COSEM: this profile allows using the DLMS/COSEM Application layer and the COSEM object model as specified in IEC 62056 5 3 and in IEC 62056 6 2 respectively. The three profiles use the same physical layer and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signalling and it is known as the Euridis Bus. The second set of profiles allows unidirectional communication between a given Energy Metering device and a Customer Energy Management System. This second set is made up of three profiles. Subclause 4.2.1 to Clause 8 included specify the bidirectional communication using twisted pair signalling and Clause 9 to 9.5 the unidirectional communication using twisted pair signalling. This second edition cancels and replaces the first edition of IEC 62056-3-1, issued in 2013, and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: • addition of a profile which makes use of the IEC 62056 DLMS/COSEM Application layer and COSEM object model; • review of the data link layer which is split into two parts: – a pure Data Link layer; – a "Support Manager" entity managing the communication media; • ability to negotiate the communication speed, bringing baud rate up to 9 600 bauds.

IEC 61970-600-1:2021 covers the definition of Common Grid Model Exchange Standard (CGMES), defines the main rules and application’s requirements to meet business requirements for assembled and merged model to fit relevant business services. This document does not define the business requirements, business processes nor how applications are implemented. This document defines how relevant Common Information Model (CIM) standards work together so that specific business requirements can be resolved. It also includes extensions to the Common Information Model (CIM). The current extensions are defined in IEC 61970-301:2020 and will be covered in its future Amendment 1, but additional extensions can be defined in other standards in the IEC 61970-600-series. The extensions can be used to define additional profiles or to expand IEC 61970-450-series or IEC 61968-13 profiles. However, primary CGMES includes additional constraints on existing profiles and validation of assembled and merged models that is based on existing profiles. This can be done by making optional attributes and associations mandatory (required). In addition, this document includes the specification of the serialisation that must be supported by referring to an existing standard defined in IEC 61970-550-series, e.g. IEC 61970-552, and making relevant constraints related to it. The goal is to achieve interoperability between applications using CGMES in a high-performance environment with combined minimum effort so that relevant business processes are satisfied. This first edition cancels and replaces IEC TS 61970-600-1 published in 2017. This edition constitutes a technical revision.

This document specifies the determination of the molar-mass distribution and the average molar mass values Mn (number average) and Mw (weight average) of polymers that are soluble in tetrahydrofuran (THF) by gel permeation chromatography (GPC).
NOTE   Also known as size exclusion chromatography (SEC).
Even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because of specific interactions (e.g. adsorption) within the sample/eluent/column system.
The conditions specified in this document are not applicable to the GPC analysis of polymer samples with Mw values greater than 106 g/mol and/or of polymers with elution limits outside the calibration range (see 7.6 and Annex C).
This document includes no correction method (e.g. for the elimination of peak broadening. If absolute molar-mass values are required, an absolute method (e.g. membrane osmometry for Mn or light scattering for Mw) can be used.

IEC 60255-187-1:2021 specifies the minimum requirements for functional and performance evaluation of (longitudinal) differential protection designed for the detection of faults in ac motors, generators and transformers. This document also defines how to document and publish performance test results. This document defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy are also included in this document. This document, together with IEC 60255-187-2 and IEC 60255-187-3, cancels and replaces IEC 60255-13. This document includes the following significant technical changes with respect to IEC 60255-13: a) IEC 60255-13 has been significantly revised to follow the common structure of the functional standards for protection relays (IEC 60255-1xx series). IEC 60255-187-1 has been developed to address the restrained and unrestrained differential protection of motors, generators and transformers. The revisions include detailed description of the functions including the performance specification, testing and documentation requirements.

This document is applicable to low voltage Photovoltaic Earth-Fault Protection Equipment (PVEFPE) whose function is to detect, interrupt, and warn system operators of earth faults in solar photovoltaic arrays. NOTE 1 In the context of this document, the PV array may include connected wiring and equipment. The required coverage of the monitoring and protection is defined in PV installation codes and standards, including aspects such as whether or not the coverage is required to include battery circuits, the DC outputs of DC-DC converters, etc. NOTE 2 The IEC definition of low voltage is 1 000 V or less for AC systems and 1 500 V or less for DC systems. PV-EFPE may be stand-alone or integrated into other equipment such as PV power conversion equipment, a PV combiner, etc. This document specifies: - the types and levels of the monitoring and protection functions that may be provided; - the nature and timing of responses to earth faults; - test methods for validating the monitoring and protection functions provided; - requirements for functional safety and fault tolerance; - requirements for product safety including construction, environmental suitability, markings, documentation, and testing.

This document specifies the determination of the molar-mass distribution and the average molar mass values Mn (number average) and Mw (weight average) of polymers that are soluble in DMAC (N,N-Dimethylacetamide) by gel permeation chromatography (GPC).
NOTE   Also known as size exclusion chromatography (SEC).
Even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because of specific interactions (e.g. adsorption) within the sample/eluent/column system.
The conditions specified in this document are not applicable to the GPC analysis of polymer samples with Mw values greater than 106 g/mol and/or polymers with elution limits outside the calibration range (see 7.6 and Annex C).
This document includes no correction method (e.g. for the elimination of peak broadening). If absolute molar mass values are required, an absolute method (e.g. membrane osmometry for Mn or light scattering for Mw) can be used.

This document specifies the determination of the molar-mass distribution and the average molar mass values Mn (number average) and Mw (weight average) of polymers that are soluble in water by gel permeation chromatography (GPC).
NOTE   Also known as size exclusion chromatography (SEC).
This method is applicable to neutral polymers and polyanions (e.g. polycarboxylates, polysaccharides, fully hydrolyzed polyvinyl alcohols and high-molecular polyethylene oxides). It is not applicable to polycations [e.g. polyvinylpyrrolidone, polyvinylpyridine, salts of poly(diallyl N,N dimethyl azacyclopentane), chitosan].
Despite good solubility in the mobile phase and even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because of specific interactions (e.g. adsorption) within the sample/eluent/column system (see also Clause 12).
The conditions specified in this document are not applicable to the GPC analysis of polymer samples with Mw values greater than 106 g/mol and/or polymers with elution limits outside the calibration range (see 7.6 and Annex C).
This document includes no correction methods (e.g. for the elimination of peak broadening). If absolute molar mass values are required, an absolute method (e.g. membrane osmometry for Mn or light scattering for Mw) can be used.
