This clause of Part 1 is applicable except as follows:
1.1 Scope
1.1.1 General
Replacement:
These particular requirements apply to electrical vacuum cleaners (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 as it is to electrical vacuum cleaners operating in dry conditions. Some additions and modifications for vacuum cleaners operating in wet conditions are under consideration. How to test robotic vacuum cleaners is under consideration for a future edition.
This part of IEC 60704 does not apply to vacuum cleaners for industrial or professional purposes.
1.1.2 Types of noise
Replacement:
The methods specified in ISO 3743‑1 , ISO 3743‑2 and ISO 3744 can be used for measuring noise emitted by electric vacuum cleaners.
1.1.3 Size of the source
Replacement:
The method specified in ISO 3744 is applicable to noise sources of any size. When applying ISO 3743‑1 and ISO 3743‑2 , care should be taken that the maximum size of the appliance under test fulfils the requirements specified in ISO 3743‑1 and ISO 3743‑2 .
1.2 Object
Addition:
This part of IEC 60704 describes the determination of the noise emission of vacuum cleaners under normal operating conditions on carpet and hard floor according to 4.6 of IEC 60312‑1:2010 .
For determining and verifying noise emission values declared in product specifications, see IEC 60704‑3 .
If a boost position is incorporated, this is not taken into account.
A boost position is a setting of a control for occasional use which results in a higher temporary fan speed.
1.3 Measurement uncertainty
Replacement:
For vacuum cleaners designed for cleaning carpets the estimated values of standard deviations of sound power levels determined according to this part of IEC 60704 are provided in Table 101:
For vacuum cleaners designed for cleaning hard floors the estimated values of standard deviations of sound power levels determined according to this part of IEC 60704 are provided in Table 102:
Addition:
1.101 Standard deviation for declaration and verification
For the purpose of determining and verifying declared noise emission values for vacuum cleaners designed for cleaning carpets according to IEC 60704‑3 , the following values provided in Table 103 apply:
For the purpose of determining and verifying declared noise emission values for vacuum cleaners designed for cleaning hard floors according to IEC 60704‑3 , the following values provided in Table 104 apply:
