This document applies to the testing of surfaces that may become contaminated by radioactive materials.
The ease of decontamination is a property of a surface and an important criterion for selecting surface
materials used in the nuclear industry, interim storage or disposal facilities from which contamination can
be removed easily and rapidly without damaging the surface. The test described in this document is a rapid
laboratory-based method to compare the ease of decontamination of different surface materials.
The results from the test can be one parameter to take into account when selecting surface coatings such
as varnish or impervious layers such as ceramics and other surfaces. The radionuclides used in this test
are those commonly found in the nuclear industry (137Cs, 134Cs and 60Co) in aqueous form. The test can also be adopted for use with other radionuclides and other chemical forms, depending on the customer requirements, if the solutions are chemically stable and do not corrode the test specimen.
The test does not measure the ease of decontamination of the surface materials in practical use, as this
depends on the radionuclide(s) present, their chemical form, the duration of exposure to the contaminant
and the environmental conditions amongst other factors.
The test method is not intended to describe general decontamination procedures or to assess the efficiency of decontamination procedures (see ISO 7503-1 to ISO 7503-3).
The test method is not suitable for use of radiochemicals if the radionuclide emits low energy gamma rays or beta particles that are readily attenuated in the surface.

This document specifies a method which applies to the preparation and validation of the standard materials generally called “large size spikes” with an uncertainty suitable for international nuclear safeguards used for measuring the content of plutonium and/or uranium by isotope dilution mass spectrometry.
This measurement methodology can be applied to input solutions of irradiated Magnox and light water reactor fuels (boiling water reactor or pressurized water reactor); in final products at spent-fuel reprocessing plants; in feed and products of mixed oxide of plutonium and uranium (MOX); and in uranium fuel fabrication

The present document defines classes of environmental conditions and their severities to which telecommunication equipment may be exposed. The severities specified are those which will have a low probability of being exceeded; generally less than 1 % of the operating time in a year. The present document applies to equipment mounted for stationary use including periods of erection work, down time, maintenance and repair at weatherprotected locations defined in clause 5.

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, uranyl nitrate hexahydrate, uranium hexafluoride and U3O8 from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.

This document is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications.
This document applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applications.
The scope of this document and its relationship with other CENELEC standards are shown in Figure 1.
This document is applicable only to the functional safety of systems. It does not deal with other aspects of safety such as occupational health and safety of personnel or potential threats created by the technology regardless of their intended functions (e.g. presence of sharp edges, presence of electric voltage, presence of combustible material). Cybersecurity aspects of functional safety are addressed only to the extent consistent with the application of the relevant standards, where needed.
This document applies to all the phases of the life cycle of a safety-related electronic system, focusing in particular on phases from 4 (specification of system requirements) to 10 (system acceptance) as defined in EN 50126 1:2017.
Requirements for systems which are not related to safety are outside the scope of this document.
This document is not necessarily applicable to systems, subsystems or equipment which had already been accepted prior to the date of withdrawal (dow) of the standards conflicting with this document. However, so far as reasonably practicable, it is applicable to modifications and extensions to such systems, subsystems and equipment.
NOTE   In the case of partial modifications, it can happen that the system can no longer be declared compliant with a single version of the standard, meaning that the modified part will be compliant with the current version and the unmodified parts will be compliant with the previous version.
This document is primarily applicable to systems, subsystems or equipment which have been specifically designed and manufactured for railway signalling applications. It is also applicable, to the extent of 6.2, to general-purpose or industrial equipment (e.g. power supplies, display screens, or other commercial off the shelf items) which is procured for use as part of a safety-related electronic system.
This document is aimed at railway duty holders, railway suppliers, and assessors as well as at safety authorities, although it does not define an approval process to be applied by the safety authorities.

This document specifies
-   the service conditions;
-   rated characteristics;
-   general structural requirements; and
-   test methods
of prefabricated traction substations for use in AC and DC electric traction systems, which as a minimum contain an enclosure and a traction switchgear designed and manufactured according to
-   EN 50123 6 in DC electric traction systems;
-   CLC/TS 50152 4 in AC electric traction systems.
Traction substations using non-type tested traction switchgear are covered by EN IEC 61936 1:2021.
NOTE 1   Due to the type testing requirements on the prefabricated traction substations only type tested traction switchgear is considered.
The enclosures of the prefabricated traction substations for use in AC and DC electric traction systems are
-   designed for outdoor installation at locations with or without public accessibility;
-   connected by insulated cable;
-   operated from inside (walk-in type) or outside (non-walk-in type).
NOTE 2   Prefabricated traction substations for railway applications are typically of the walk-in type due to the rating and resulting dimensions of the AC or DC traction switchgear.
Prefabricated traction substations can be situated at ground level or partially or completely below ground level.
In general a prefabricated traction substation comprises an enclosure, a traction switchgear and can include the following additional main components:
-   power transformers;
-   electronic power converters;
-   high-voltage and/or low-voltage switchgear and controlgear;
-   high-voltage and/or low-voltage interconnections;
-   auxiliary equipment and circuits.
However, relevant provisions of this document are applicable to designs where not all these main components exist.
NOTE 3   The term "main component”"is defined in 3.3.103 of EN IEC 62271 202:2022.
NOTE 4   For example, a switching station in an AC electric traction system consisting of an AC metal-enclosed traction switchgear and auxiliary circuits only.
NOTE 5   EN IEC 61936 1:2021 provides general rules for the design and erection of high-voltage power installations. As well, it specifies additional requirements for the external connections, erection and operation at the place of installation of high-voltage prefabricated traction substations compliant with EN IEC 62271 202:2022, which are regarded as a main component of such installation. Non-prefabricated traction substations, are generally covered by EN IEC 61936 1:2021.
This document covers designs using natural ventilation and/or any other kind of cooling system.
Due to the large number of different main components being addressed in this document the expression "main components shall comply with (the applicable subclause of) their specific product standard" is used in this document. This means that reference is to
-   EN 50123 6:2003  for DC traction switchgear;
-   to other parts of the EN 50123 series for switching devices also measurement, control and protection devices for DC traction applications;
-   CLC/TS 50152 4:2021 for AC traction switchgear;
-   other parts of the EN 50152 series for switching devices and also measurement, control and protection devices for AC traction applications;
-   EN 50328:2003  for electronic power converters;
-   EN 50329:2003  for traction power transformers;
-   EN IEC 61439-1:2021  for low-voltage non-traction switchgear; and
-   EN IEC 62271 200:2021  for high-voltage non-traction switchgear.

This document is applicable to safety-related electronic systems using for digital communication purposes a transmission system which was not necessarily designed for safety-related applications. For transmission systems where the risk of unauthorized access is not negligible, the document defines the interface to the applicable cybersecurity standards.
Both safety-related equipment and non-safety-related equipment can be connected to the transmission system.
This document gives the specific requirements needed to achieve safety-related communication between safety-related equipment connected to the transmission system, while the general system requirements including allocation of safety requirements and content of the safety case are defined in EN 50129.
This document is not applicable to existing systems which had already been accepted prior to the release of this document. However, so far as reasonably practicable, it is applicable to modifications and extensions to existing systems, subsystems and equipment.
This document does not specify:
-   the transmission system;
-   equipment connected to the transmission system;
-   solutions (e.g. for interoperability);
-   which kind of data are safety-related and which are not.
A safety-related equipment connected through an open transmission system can be subjected to many different cybersecurity threats, against which an overall program is defined encompassing management, technical and operational aspects.
