This clause of Part 1 is replaced by the following.

This part of IEC 60335 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 600 V for multi-phase, 600 V direct-current (DC) motor-compressors.

This standard also covers

multi-speed motor-compressors, that are motor-compressors, the speed of which can be set to different values;

variable capacity motor-compressors that are motor-compressors where the capacity of the compressor is controlled at fixed speeds.

NOTE 101 Examples of equipment which contain motor-compressors are

tumble dryers (IEC 60335-2-11);

refrigerating appliances, ice-cream appliances and ice-makers (IEC 60335-2-24);

electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40);

commercial dispensing appliances and vending machines (IEC 60335-2-75);

commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or compressor (IEC 60335-2-89);

safety requirements for electrical equipment for measurement, control, and laboratory use – Particular requirements for refrigerating equipment (IEC 61010-2-011);

professional ice-cream makers (IEC 60335-2-118);

professional systems and heat pumps (ISO 5149-2);

This standard does not supersede the requirements of standards relevant to the particular appliance in which the motor-compressor is used. However, if the motor-compressor type used complies with this standard, the tests for the motor-compressor specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the motor-compressor control system is associated with the particular appliance control system, additional tests could be necessary on the final appliance.

So far as is practical, this standard deals with the common hazards presented by motor-compressors used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account

the use of appliances by young children or infirm persons without supervision;

playing with the appliances by young children.

NOTE 102 Attention is drawn to the fact that

for motor-compressors intended to be used in appliances in vehicles or on board ships, additional require­ments could be necessary;

motor-compressors used in 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), additional require­ments could be necessary;

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

 

This standard does not apply to

motor-compressors designed exclusively for industrial purposes.

This document concerns carbon-based grades that are used for sliding electrical contacts, such as carbon brushes or pantograph strips.

By extension, it is possible to use the test procedures of this document to all electrical sliding contacts for electrical transmission appliances and to other appliances of carbon-based materials (heat exchangers, bearings…).

This document specifies uniformized procedures for determining their following properties:

density and porosity;

resistivity;

flexural strength;

hardness;

ash content.

In addition, it provides recommendations on test procedures for other properties:

Mechanical properties: Charpy impact test, compression strength, tensile strength (Annex B).

Thermal properties: coefficient of thermal expansion, specific heat capacity, thermal conductivity (Annex C).

The properties determined by these tests are inherent of the carbon-based materials themselves as distinct from performance characteristics in operation on electrical equipment (carbon brush in an electrical rotating machine, contact strips on a pantograph, etc.).

It should be kept in mind that since these materials are generally brittle, porous materials, it is reasonable that their properties vary much more than the same properties in metals.

Some test methods are suitable for use in production quality control (routine tests), others only for more thorough investigations, using precise laboratory techniques (see Annex A).

WARNING — The use of this International Standard can involve hazardous materials, operations and equipment. It does not purport to address all of the safety or environmental problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This part of IEC 62351 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations.

Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations.

The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like teleprotection, telecontrol, substation automation, synchrophasors, inverters and protections) need instead a specific solution for monitoring their health.

The NSM objects provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects.

In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in this part of IEC 62351, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided.

The objects that are already covered by existing MIBs are not defined here but are expected to be compliant with existing MIB standards.

refrigerating appliances used in farm houses and by clients in hotels, motels and other residential type environments,

refrigerating appliances used in bed and breakfast type environments, and

refrigerating appliances used in catering and similar non-retail applications

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 whose

physical, sensory or mental capabilities or

lack of experience and knowledge

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

NOTE 1 Attention is drawn to the fact that

for appliances intended to be used in vehicles, leisure accommodation vehicles, boats for leisure purposes, on board ships or aircraft, additional requirements can be necessary;

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