Frequently Asked Questions
ICS 91.140.60 is a classification code in the International Classification for Standards (ICS) system. It covers "Water supply systems". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 804 standards classified under ICS 91.140.60 (Water supply systems). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document specifies the metrological and technical requirements for water meters for cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the accumulated volume. In addition to water meters based on mechanical principles, this document applies to devices based on electrical or electronic principles, and mechanical principles incorporating electronic devices, used to measure the volume of cold potable water and hot water. This document also applies to electronic ancillary devices. Ancillary devices are optional. However, it is possible for national or regional regulations to render some ancillary devices mandatory in relation to the utilization of water meters. NOTE Any national regulations apply in the country of use.

This document applies to water meters used to meter the volume of cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume. This document specifies technical characteristics and pressure loss requirements for meters for cold potable water and hot water. It applies to water meters which can withstand: a) a maximum admissible pressure (MAP) equal to at least 1 MPa1) [0,6 MPa for meters for use with pipe nominal diameters (DNs) ≥500 mm]; b) a maximum admissible temperature (MAT) for cold potable water meters of 30 °C; c) a MAT for hot water meters of up to 180 °C, depending on class. In addition to meters based on mechanical principles, this document also applies to water meters based on electrical or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to meter the volume flow of hot water and cold potable water. It also applies to electronic ancillary devices. As a rule ancillary devices are optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter. 1) 1 MPa = 10 bar (1 bar = 0,1 MPa =105 Pa; 1 MPa = 1 N/mm2).

This document is applicable to the type evaluation and initial verification testing of water meters for cold potable water and hot water as defined in ISO 4064-1:2024|OIML R 49‑1:2024. OIML Certificates of conformity can be issued for water meters under the scope of the OIML Certificate System, provided that this document, ISO 4064-1:2024|OIML R 49‑1:2024 and ISO 4064-3:2024|OIML R 49‑3:2024 are used in accordance with the rules of the system. This document sets out details of the test programme, principles, equipment and procedures to be used for the type evaluation, and initial verification of a meter type. The provisions of this document also apply to ancillary devices, if required by national regulations. The provisions include requirements for testing the complete water meter and for testing the measurement transducer (including the flow or volume sensor) and the calculator (including the indicating device) of a water meter as separate units.

IEC SRD 63301-1:2024 provides an overview of water systems in smart cities, establishes a general approach for use case collection and analysis, and identifies major stakeholders and application areas for high-level analysis of water systems.
The construction of a smart city can create benefits for a society and its stakeholders. Water is a critical resource to support urban development and its sustainable use is recognized as a UN Sustainable Development Goal. Water infrastructure development, water management efficiency, water supply resilience, and the safe operation and use of water are important focal areas for smart cities.
This document focuses on water systems management, specifically water security whether directly from a natural source or via man-made infrastructure. Information and communications technologies (ICT) and electro-technologies can provide greater visibility and control, however their application does depend on the characteristics of individual water markets. Technology is not a panacea for resolving all issues and problems.
A gap exists in effective coordination and clear orientation and how industry and stakeholders are engaged within it.
Major stakeholders of water management and use include citizens, the water authority (government), and organizations (associations, business groups, utility companies). Each stakeholder has different and competing interests, market relationships and touch points to water system infrastructure, processes, operations, management and use.
Modelling these complex interactions into a systems architecture is a valuable exercise in understanding the issues, gaps and opportunities for sustainable water management.
This document focuses on use case collection and analysis to elicit requirements to support technical committees in preparing sustainable water management standards for cities and communities.

This document specifies materials and the general aspects of polyethylene (PE) pressure piping systems (mains and service pipes) for buried or above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drains and sewers under pressure, vacuum sewer systems, and water for other purposes, with the exception of industrial application.
NOTE 1 For PE components intended for the conveyance of water intended for human consumption and raw water prior to treatment attention is drawn to Clause 6 of this document. Components manufactured for water for other purposes, drains and sewers, and vacuum systems are possibly not suitable for water supply for human consumption.
NOTE 2 Industrial application is covered by EN ISO 15494 [6].
The intended use includes sea outfalls, laid in water and pipes suspended below bridges.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 12201-2, EN 12201 3, EN 12201 4 and EN 12201 5, this document is applicable to PE pipes, fittings and valves, their joints and joints with components of PE and other materials intended to be used under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar ;
b) an operating temperature of 20 °C as a reference temperature.
NOTE 3 For applications operating at constant temperatures greater than 20 °C and up to and including 50 °C, see Annex A.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours.
NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
