This clause of Part 1 is applicable except as follows:

1.1 Scope

1.1.1 General

Addition:

These particular requirements apply to electrical range hoods and other cooking fume extractors for household and similar use intended for filtering the air of a room or for exhausting the air out of a room, including their accessories and their component parts. It also applies to cooking fume extractors with an external fan which may be mounted inside or outside of the room where the range hood is located or a down-draft system that is arranged beside, behind or under the cooking surface.

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 cooking fume extractors.

1.1.3 Size of 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 cooking fume extractor under test fulfils the requirements specified in 1.2 of ISO 3743‑1 and 1.3 of ISO 3743‑2 .

1.2 Object

Addition:

This standard describes the determination of the noise emission of household cooking fume extractors under normal operating conditions and at the highest fan speed setting for normal use.

NOTE 101

If a boost position is incorporated, this is not taken into account (see 6.5 of IEC 61591:1997 ).

NOTE 102

A boost position is a setting of a control for occasional use, which results in a higher temporary fan speed (see 6.5 of IEC 61591:1997 ).

Requirements for the declaration of noise emission values are not within the scope of this standard.

NOTE 103

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 according to this standard, are as follows (see Table 101):

Table 101
Standard deviations of sound power levels

Addition:

1.101 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 (see Table 102):

Standard deviations for declaration and verification
