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)

sr (repeatability)

sR (reproducibility)

1,0

2,0

 

Addition:

Standard deviation for declaration and verification

For the purpose of determining and verifying declared noise emission values according to IEC 60704-3, the following values apply:

Table 102 - Standard deviations for declaration and verification[2]

Standard deviation (dB)

sP (production)

st (total)

sM (reference)

1,0 to 1,5

2,0

2,0

 
 

[1] The values in the standard deviation tables will be further considered and improved.
