IEC 60704-2-17-2020 pdf download.Household and similar electrical appliances – Test code for the determination of airborne acoustical noise – Part 2-17: Particular requirements for dry-cleaning robots.
This clause of IEC 60704-1 :201 0 is applicable except as follows:
1.1 Scope
1.1.1 General
Replacement:
These particular requirements apply to electrical dry-cleaning robots (including their accessories and their component parts) for household use or under conditions similar to those in households. This part of IEC 60704-2 applies to electrical dry-cleaning robots operating in dry conditions only.
NOTE Some additions and modifications for dry-cleaning robots operating in wet conditions are under consideration.
This part of IEC 60704-2 does not apply to dry-cleaning robots for industrial or professional purposes.
This document does not apply to
– manually operated vacuum cleaners, and
– dry-cleaning robots for outdoor use.
1.1.2 Types of noise
Replacement:
The methods specified in ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by electric dry-cleaning robots.
1.1.3 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 Clause 5 of ISO 3743-2:201 8. Although the dry-cleaning robot itself is a relatively small source, the covered floor area during the measurement comprises a much larger effective source.
1.2 Object
Addition:
This part of IEC 60704 describes the determination of the noise emission of dry-cleaning robots under normal operating conditions on carpet and hard floors.
NOTE 1 01 For determining and verifying noise emission values declared in product specifications, see IEC 60704-3.
1.3 Measurement uncertainty
Replacement:
The estimated values of standard deviations of sound power levels, determined in accordance with this document, are given in Table 1 01 .
1.1 01 Standard deviation for declaration and verification
For the purpose of determining and verifying declared noise emission values in accordance with IEC 60704-3, the values are given in Table 1 02.
