scope:

General

This part of IEC 60704 is applicable for the determination of airborne acoustical noise of mains operated and cordless dry vacuum cleaners for household use or under conditions similar to those in households.

This part of IEC 60704 does not apply to vacuum cleaners for industrial or professional purposes.

NOTE Particular requirements for dry cleaning robots are specified in IEC 60704-2-17.

Types of noise

The methods specified in ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by electric vacuum cleaners.

Size of the source

The method specified in ISO 3744 is applicable to noise sources of any size. When applying ISO 3743-1 and ISO 3743-2, the maximum size of the appliance under test should fulfil the requirements specified in 1.2 of ISO 3743-1:2010 and 1.3 of ISO 3743-2:1994.

Object

This part of IEC 60704 describes the determination of the noise emission of vacuum cleaners under normal operating conditions on carpet and hard floor in accordance with 4.6 of IEC 62885-2.

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

Measurement uncertainty

For vacuum cleaners designed for cleaning carpets the estimated values of standard deviations of sound power levels determined in accordance with 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 in accordance with this part of IEC 60704 are provided in Table 102.

NOTE 101 The values in Table 101 and Table 102 are derived from the results of a round robin test (RRT) conducted in 2010/2011 with 4 different vacuum cleaners (passive and active) in 8 participating laboratories.

Standard deviation for declaration and verification

For the purpose of determining and verifying declared noise emission values for vacuum cleaners designed for cleaning carpets, in accordance with 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, in accordance with IEC 60704-3, the following values provided in Table 104 apply:
