This European Standard specifies general requirements for the construction, testing and performance of electrically operated carbon monoxide gas detection apparatus, designed for continuous operation in domestic premises. The apparatus may be mains-powered or battery-powered. Such apparatus is intended to warn of an accumulation of CO, enabling the occupant to react before being exposed to significant risk.

Additional requirements for apparatus to be used in recreational vehicles and similar premises are specified in EN 50291‑2.

NOTE 1     For caravan holiday homes EN 50291–1 applies.

This European Standard specifies two types of apparatus, these are:

—    type A – to provide a visual and audible alarm and an executive action in the form of a transmittable output signal that can be used to actuate directly or indirectly a ventilation or other ancillary device;

—    type B – to provide a visual and audible alarm only.

NOTE 2     Both type A and type B apparatus can be interconnected.

This European Standard excludes apparatus for:

—    the detection of combustible gases, other than carbon monoxide itself (see EN 50194‑1);

—    the detection of CO in industrial installations (see EN 45544‑1, EN 45544‑2 and EN 45544‑3) or commercial premises;

—    CO measurement for smoke and fire detection;

—    CO measurement in carparks and tunnels.

NOTE 3     See EN 50545–1.

This European Standard deals with the performance of clothes washing machines intended to be used by trained users e.g. in hotels, hospitals, factories, in light industry and on farms. It also covers washing machines declared for commercial use in public areas and operated by lay persons e.g. in launderettes, apartment houses and communal laundry rooms. The clothes washing machines can be utilizing cold and/or hot water supply and without heating or with heating devices for electricity, steam or gas. This European standard covers top, front and side loaded clothes washing machines with horizontal or vertical axis and with one or more wash compartments. It also deals with appliances for both washing and drying textiles (washer-dryers) with respect to their washing related functions and to separate spin extractors related to their dewatering capabilities.

NOTE 1       Performance of tumble dryers declared for commercial use is assessed in prEN 50594:2017.

NOTE 2       The object is to state and define the principal performance characteristics of clothes washing machines declared for commercial use and to describe the test methods for measuring these characteristics.

NOTE 3       This European standard does not apply to continuous batch washing machines (e.g. tunnel washers) or washing machines only possible to operate with automatic loading and unloading.

NOTE 4       This European standard does not specify safety requirements for clothes washing machines declared for commercial use. Safety requirements are specified in EN 50571 and the EN ISO 10472‑ series.

This European Standard is applicable to tumble dryers intended to be used by trained users e.g. in hotels, hospitals, factories, in light industry and on farms. It covers tumble dryers declared for commercial use in public areas and operated by lay persons e.g. in launderettes, apartment houses and communal laundry rooms. This European standard covers tumble dryers which use electricity, gas or steam as a heating source.

The object is to state and define the principal performance characteristics of tumble dryers for commercial use of interest to users and to describe standard methods for measuring these characteristics.

NOTE          It does not apply to transfer tumble dryers or tumble dryers with automatic loading and unloading.

This clause of Part 1 is replaced by the following.

This International Standard deals with the safety of electric whirlpool baths for indoor use and whirlpool spas, for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.

This standard also applies to appliances for circulating air or water in conventional baths.

Appliances not intended for normal household use but that nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in hotels, fitness centres and similar places, are within the scope of this standard.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account

persons (including children) whose

physical, sensory or mental capabilities; or

lack of experience and knowledge

prevents them from using the appliance safely without supervision or instruction;

children playing with the appliance.

NOTE 101 Attention is drawn to the fact that

–    for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;

–    in many countries additional requirements are specified by the national health authorities, the national water supply authorities, the national authorities responsible for the protection of labour and similar authorities.

NOTE 102 This standard does not apply to

–    equipment for water circulation in swimming and motion exercise pools;

–    cleaning appliances for swimming pools;

–    appliances intended for medical purposes;

–    appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

This part of IEC 61968 specifies the distribution extensions of the common information model (CIM) specified in IEC 61970-301. It defines a standard set of extensions of common information model (CIM), which support message definitions in IEC 61968-3 to IEC 61968-9, IEC 61968-13 and IEC 61968-14. The scope of this standard is the information model that extends the base CIM for the needs of distribution networks, as well as for integration with enterprise-wide information systems typically used within electrical utilities. The information model is defined in UML which is platform-independent and electronically processable language that is then used to create message payload definitions in different required formats. In this way, this standard will not be impacted by the specification, development and/or deployment of next generation infrastructures, either through the use of standards or proprietary means.

For the purposes of this part of IEC 61968, the distribution CIM (DCIM) model refers to the IEC CIM model as defined by IEC 61970-301 and this part of IEC 61968.

The common information model (CIM) is an abstract model of the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of software applications developed independently by different vendors. The CIM facilitates integration by defining a common language (i.e., semantics and syntax) based on the CIM to enable these applications or systems to access public data and exchange information independent of how such information is represented internally.

IEC 61970-301 defines a core CIM for energy management system (EMS) applications, including many classes that would be useful in a wider variety of applications. Due to its size, the CIM classes are grouped into logical packages, and collections of these packages are maintained as separate International Standards. This document extends the core CIM with packages that focus on distribution management systems (DMS) including assets, work, customers, load control, metering, and others. IEC 62325-301 extends the CIM with packages that focus on market operations and market management applications. Other CIM extensions may be published as International Standards, each maintained by a separate group of domain experts. Depending on a project’s needs, the integration of applications may require classes and packages from one or more of the CIM standards.
