General

Replacement:

These particular requirements apply to electrical dry cleaning robots (including their accessories and their component parts) for household use in or under conditions similar to those in households. This part of IEC 60704 applies to electrical robot vacuum cleaners operating in dry conditions only. Some additions and modifications for robot vacuum cleaners operating in wet conditions are under consideration.

This part of IEC 60704 does not apply to dry cleaning robots for industrial or professional purposes.

This standard does not apply to

manual operated vacuum cleaners and

robot vacuum cleaners for outdoor use.

Types of noise

Replacement:

The methods specified in ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by electric robot vacuum cleaners.

Size of the source

Replacement:

The method specified in ISO 3744 is applicable to noise sources of any size. Limitations for the size of the source are given in 1.3 ISO 3743-2. Although the robot vacuum cleaner itself is a relatively small source, the covered floor area during the measurement comprises a much larger effective source.

Object

Addition:

This part of IEC 60704 describes the determination of the noise emission of robot vacuum cleaners under normal operating conditions on carpet and hard floors.

NOTE 101   For determining and verifying noise emission values declared in product specifications, see IEC 60704-3.

The following quantities are used:

–    A-weighted sound power level, LWA and

–    octave band sound power levels.

In general, the described methods are specified for appliances without an operator present.

Methods for determining sound power levels with precision accuracy (grade 1 according to ISO 12001), specified for example in ISO 3741 and ISO 3745, are not included in this standard. They may, however, be applied if the appropriate test environment and instrumentation are available.

NOTE 101 The noise values obtained under the described conditions of this part will not necessarily correspond with the noise experienced under the operational conditions of practical use.

NOTE 102 For quality control during production etc., simplified methods may be appropriate. For noise reduction purposes, other measurement methods employing, for example, narrow-band analysis or intensity techniques usually will have to be applied. These methods are not covered by this part.

Measurement uncertainty

Replacement:

The estimated values of standard deviations of sound power levels determined according to this standard are:

Table 101 - Standard deviations of sound power levels[1]

Standard deviation (dB)

The purpose of this part of IEC 60077 gives additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2.

NOTE In this document the term high voltage fuses is used in the context of the voltages used in the field of railway rolling stock.

The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1 500 V.

NOTE Certain of these rules, after agreement between the user and the manufacturer, are used for fuses installed on vehicles other than rail rolling stock such as mine locomotives, trolleybuses, etc.

This document together with IEC 60077-2 states specifically:

a)  the characteristics of the fuses;

b)  the service conditions with which the fuses complies with reference to:

–   operation and behaviour in normal service;

–   operation and behaviour in case of short circuit;

–   dielectric properties.

c)  the tests intended for confirming the compliance of the fuse with the characteristics under the service conditions and the methods adopted for these tests;

d)  the information marked on, or given with, the fuse.

This document does not cover parallel connection of fuses.

During preparation of this document, IEC 60269-1 and IEC 60282-1 have been considered and their requirements have been kept as far as possible.

This document makes reference to the general rules for electrotechnical components given in IEC 60077-2, but for general conditions reference is made directly to IEC 60077-1.

This Part of IEC 61968 series, is the first in a series that, taken as a whole, define interfaces for the major elements of an interface architecture for distribution management.

This International Standard identifies and establishes recommendations for standard interfaces based on an Interface Reference Model (IRM). Subsequent clauses of this standard are based on each interface identified in the IRM. This set of standards is limited to the definition of interfaces. They provide for interoperability among different computer systems, platforms, and languages. Methods and technologies used to implement functionality conforming to these interfaces are recommended in IEC 61968-100.

As used in IEC 61968, distribution management consists of various distributed application components for the utility to manage electrical distribution networks. These capabilities include monitoring and control of equipment for power delivery, management processes to ensure system reliability, voltage management, demand-side management, outage management, work management, network model management, facilities management, and metering. The IRM is specified in Clause 3.

This document applies to residual current monitors having rated voltages not exceeding 440 V AC and rated currents not exceeding 125 A for household and similar purposes.

RCMs are intended to monitor the residual current of the installation and to give a warning if the residual current between a live part and an exposed conductive part or earth exceeds a predetermined level.

RCMs covered by this standard are not intended to be used as protective devices.

RCMs detect residual currents that may circulate in an AC circuit (e.g. residual alternating current, residual pulsating direct current, residual smooth direct current), whether suddenly applied or slowly rising.

NOTE 1 RCM for DC systems are under consideration.

This document applies to monitors performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating current of the device and providing the prescribed warning signal(s) when the residual current exceeds this value.

RCMs having internal batteries are not covered by this document.

The requirements of this document apply for normal environmental conditions (see 7.1). Additional requirements may be necessary for RCMs used in locations having severe environmental conditions.

This document does not cover Insulation Monitoring Devices (IMDs) which are covered by the scope of IEC 61557-8.

NOTE 2 An RCM is distinguished from an IMD in that it is passive in its monitoring function and only responds to an unbalanced fault current in the installation being monitored. An IMD is active in its monitoring and measuring functions in that it can measure the balanced and unbalanced insulation resistance or impedance in the installation (see IEC 61557-8).
