This document provides guidelines for the management of wastewater utilities and the assessment of wastewater services.
This document is applicable to publicly and privately owned and operated wastewater utilities but does not favour any particular ownership or operational
model.

NOTE 1 Wastewater is always generated when water is used or consumed. Accordingly, sources of wastewater can be residential, industrial, commercial or
institutional. Collected storm water or (melted) snow can also be considered as wastewater, as it often carries contaminants and pathogens picked up from
air or ground surfaces on its way to a collection system. In certain circumstances, especially in undeveloped areas, sanitary waste is collected in an
undiluted form.
This document addresses wastewater systems in their entirety and is applicable to systems at any level of development (e.g. pit latrines, on-site systems,
networks, treatment facilities).
The following are within the scope of this document:
— the definition of a language common to different stakeholders;
— objectives for the wastewater utility;
— guidelines for the management of wastewater utilities;
— service assessment criteria and related examples of performance indicators, all without setting any target values or thresholds.
The following are outside the scope of this document:

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1000 V alternate current or 1500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics, such as:

• general industrial equipment,

• electrical facilities,

• electrical machines,

• electrical appliances for household and similar use,

• information technology and business equipment,

• building automation equipment,

• automation equipment,

• electrical installation equipment,

• medical equipment,

• control equipment,

• telecommunications,

• vehicles,

• transportation (e.g. railways).

Compliance with the requirements of this standard is verified by the type tests indicated.

In case the application of a relay determines additional requirements exceeding those specified in this standard, the relay should be assessed in line with this application in accordance with the relevant IEC standard(s) (e.g. IEC 60730-1, IEC 60335-1, IEC 60950-1).

1.1  Généralités

La présente norme énonce les exigences relatives à la gestion du vieillissement des enceintes de confinement en béton des centrales nucléaires et leurs éléments, et s’adresse aux propriétaires, exploitants, concepteurs, fabricants et constructeurs des enceintes de confinement en béton et de leurs éléments.

Les enceintes de confinement en béton comprennent les éléments structuraux et non structuraux suivants :

le béton;

le renforcement (avec et sans précontrainte);

l’acier (p. ex., membrane protectrice, pièces encastrées, ancrages);

les systèmes de membranes protectrices non métalliques et de revêtement;

les garnitures de joint et les arrêts d’eau; et

les éléments nécessaires au support des enceintes de confinement (p. ex., fondations).

Notes : La présente norme peut fournir des conseils concernant la gestion du vieillissement d’autres structures en béton, le cas échéant.

Les exigences relatives à la gestion du vieillissement des composants de confinement sont énoncées dans CSA N290.20.

1.2  Enceintes de confinement en béton existantes

La présente norme énonce les exigences relatives à la gestion du vieillissement des enceintes de confinement en béton existantes afin d’être en mesure de traiter les problèmes émergents et d’assurer que les enceintes de confinement en béton et leurs éléments existants répondent aux exigences fonctionnelles et aux exigences de performance qui les concernent au cours des diverses phases de leur cycle de vie.

Note : Les exigences de la série CSA N287 pourraient varier en fonction de la phase du cycle de vie de la structure, notamment la conception, la construction, la mise en service, l’exploitation (y compris l’exploitation à long terme et l’arrêt prolongé) et le déclassement.

This Standard provides aging management requirements for concrete containment structures and their elements for nuclear power plants and is directed to the owners/operating organizations, designers, manufacturers, fabricators, and constructors of the concrete containment structures and their elements.

Concrete containment structures include the following structural and non-structural elements:

concrete;

reinforcement (pre-stressed and non-prestressed);

steel (e.g. liner, embedded parts, anchors);

non-metallic liners and coating systems;

joint sealants and water stops; and
