Water efficiency management systems — Requirements with guidance for use

Systèmes de management de l'utilisation efficiente de l'eau — Exigences et recommandations d'utilisation

This document specifies requirements and contains guidance for its use in establishing, implementing and maintaining a water efficiency management system. It is applicable to organizations of all types and sizes that use water. It is focused on end-use consumers.

This document is applicable to any organization that wishes to:

a) achieve the efficient use of water through the ?reduce, replace or reuse' approach;

b) establish, implement and maintain water efficiency;

c) continually improve water efficiency.

This document specifies requirements and contains guidance for its use regarding organizational water use. It includes monitoring, measurement, documentation, reporting, design and procurement practices for equipment, systems, processes and personnel training that contribute to water efficiency management.

NOTE 1 ?Reduce' includes the use of water-efficient fittings and equipment and, for example, putting in place a proper monitoring system for usage and leak detection.

NOTE 2 ?Replace' includes substitution of drinking water with reclaimed water, sea water and rainwater wherever feasible.

NOTE 3 ?Reuse' includes recycling of, for example, process water or grey water. For utilizing water reuse systems, ISO/TC 282 documents can be referred to as guidelines.

NOTE 4 Guidance in the annexes provides additional practical information to support implementation. Annex A provides guidance on the use of this document and Annex B gives examples of scenarios in water efficiency.


Reciprocating internal combustion engine driven alternating current generating sets — Part 1: Application, ratings and performance

Groupes électrogènes à courant alternatif entraînés par moteurs alternatifs à combustion interne — Partie 1: Application, caractéristiques et performances

ISO 8528-1:2018 defines various classifications for the application, rating and performance of generating sets consisting of a Reciprocating Internal Combustion (RIC) engine, Alternating Current (a.c.) generator and any associated controlgear, switchgear and auxiliary equipment.

ISO 8528-1:2018 applies to a.c. generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives.

For some specific applications (e.g. essential hospital supplies, high-rise buildings), supplementary requirements can be necessary. The provisions of this document can be the basis for establishing any supplementary requirements.

For other reciprocating-type prime movers (e.g. sewage-gas engines, steam engines), the provisions of this document can be used as a basis for establishing these requirements.

Generating sets meeting the requirements of this document are used to generate electrical power for continuous, peak-load and standby applications. The classifications laid down in this document are intended to help understanding between manufacturer and customer.

Internet of Things (IoT) and digital twin — Vocabulary

This document provides a definition of Internet of Things and digital twin along with a set of terms and definitions. This document is a terminology foundation for the Internet of Things and digital twin. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision. This edition includes the following technical changes with respect to the previous edition: a) addition of new terms which are used in other ISO/IEC IoT related standards; b) update of some definitions to align with current usage in IoT standards; c) extension of digital twin related vocabularies with title and scope changes


Internet of things (IoT) — Interoperability for IoT systems — Part 1: Framework

Internet des objets (IoT) — Interopérabilité des systèmes IoT — Partie 1: Cadre méthodologique

ISO/IEC 21823-1:2019(E) provides an overview of interoperability as it applies to IoT systems and a framework for interoperability for IoT systems. This document enables IoT systems to be built in such a way that the entities of the IoT system are able to exchange information and mutually use the information in an efficient way. This document enables peer-to-peer interoperability between separate IoT systems. This document provides a common understanding of interoperability as it applies to IoT systems and the various entities within them.


Internet of Things (IoT) — Reference architecture

This document provides a standardized IoT Reference Architecture using a common vocabulary, reusable designs and industry best practices. It uses a top down approach, beginning with collecting the most important characteristics of IoT, abstracting those into a foundational view, then providing five more views including a construction view with a set of architecture and design patterns for building IoT systems.

This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

1. conformance with ISO/IEC/IEEE 42010:2022;

2. improved usability;

3. implementation pattern support.
