CEN - European Committee for Standardization

Industrial symbiosis is the use by one company or sector of underutilised resources broadly defined (including waste, by-products, residues, energy, water, logistics, capacity, expertise, equipment and materials) from another, with the result of keeping resources in productive use for longer. It presents a systems approach to a more sustainable and integrated industrial economy that identifies business opportunities to improve resource utilisation and productivity. The objectives of this CEN Workshop Agreement (CWA) are to support the mainstream adoption of good practice approaches proven through implementation by advancing the mutual understanding of actors (public, private, third sector, and community) currently using the term industrial symbiosis in different ways. This CWA is intended to help the above actors consider and implement industrial symbiosis.

This European Standard does not apply to the structural design of the lining system.
NOTE   Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this European Standard.

1.1   Scope of EN 19100-2
(1) This document gives basic structural design rules for glass components and assemblies primarily subjected to out-of-plane loading.
NOTE   Out-of-plane loads are loads acting normal to (e.g. wind) or having a component (e.g. dead load, snow) acting normal to the glass plane.
1.2   Assumptions
(1) The assumptions given in EN 1990-1 apply.

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, U3O8, uranyl nitrate hexahydrate and uranium hexafluoride 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 defines the terms used in the ISO standards on the identification of medicinal products (IDMP) and their related technical specifications.

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.

The scope of this TR is a Public Transport common glossary to harmonise terms and definitions from existing data dictionaries.
The methodology consisting of highlighting the differences between various use contexts arises from a number of factors, many of them practical:
1) The facts of history. Many of the legislations, as noted (especially EU Regulations, EC Delegated Regulations and EC Implementing Decisions), already have mandatory application of varying scope, and the regulatory bodies would be most unlikely to consider it worthwhile to actually modify them in line with some list of precise terms developed after the fact.
2) The diversity of practices and use-cases which have been included in the Public Transport domain. Especially as a result of the need for this domain to cover multi-modality and developing technologies, and the increasing requirement for Public Transport to interact with wider domains such as Road Traffic Management, there are bound to be some deeply embedded terms which have been used in different senses in different domains.
3) The differing nature and working practices involved in the legislative, regulatory and technical standardisation processes, and their relationship both to one another and to real-world implementors of Public Transport services.
4) The prior existence of a well-established and precise set of Conceptual Models, including terms and definitions, in the Transmodel ecosystem. This is self-consistent and clearly defined and is being maintained on a continuous basis. However, its use in a legislative context is by “delegation”, which may do little to decrease the possibility of regulations themselves making use of some terms in a sense not intended by Transmodel itself.
The format of the glossary will be structured around following sections:
-   Contexts: Summary of the contexts in which the term or phrase is defined.
-   Related terms: Phrases in which the term is used, either as an element in a compound (e.g. the term “access” vs “access right” or where a related term is used which carries a notably different association (e.g. the term “access” vs “accessibility”, where the latter has a precise meaning in some contexts).
-   Concept: Where it is possible to identify a unifying concept among the various definitions. An informal or explanatory summary of that concept. Where it is not possible, a note of that fact.
-   Harmonisation: Containing references and links to the definitions in their contexts and the suggested conventions for citing them in contexts other than those where they are defined.
-   Source references: Links to definitions of the exact term in their contexts.
-   Usage recommendations: Recommendations for how the terms should be cited in contexts outside that in which the term is defined.
