This clause of PartĀ 1 is applicable except as follows:

1.1 Scope

1.1.1 General

Addition:

These particular requirements apply to single-unit electric washer-dryers for household and similar use intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter.

1.1.2 Types of noise

Replacement:

The methods specified in ISOĀ 3743‑1, ISOĀ 3743‑2 and ISOĀ 3744 can be used for measuring noise emitted by washer-dryers.

1.1.3 Size of the source

Replacement:

The method specified in ISOĀ 3744 is applicable to noise sources of any size. When applying ISOĀ 3743‑1 and ISOĀ 3743‑2, care should be taken that the maximum size of the washer-dryers under test fulfils the requirements specified in 1.2 of ISOĀ 3743‑1:2010 and 1.3 of ISOĀ 3743‑2:1994.

1.2 Object

Addition:

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

NOTEĀ 101 For determining and verifying noise emission values declared in product specifications, see IECĀ 60704‑3.

1.3 Measurement uncertainty

Replacement:

For washer-dryers, the estimated values of standard deviations of sound power levels, determined in accordance with this document are as indicated in TableĀ 101 and 102.

TableĀ 101

Standard deviations of sound power levels of washing and spinning final results for washer-dryer

Standard deviation (dB)
σr (repeatability) σR (reproducibility)
0,6 1,0

TableĀ 102

Standard deviations of sound power levels of drying final results for washer-dryer

Standard deviation (dB)
σr (repeatability) σR (reproducibility)
0,4 0,8

1.101 Standard deviation for declaration and verification

For the purpose of determining and verifying declared noise emission values for washing and spinning for washer-dryers in accordance with IECĀ 60704‑3, the values indicated in TableĀ 103 apply.

TableĀ 103

Standard deviations for declaration and verification for washing and spinning final results for washer-dryer

Standard deviation (dB)
σP (production) σt (total) σM (reference)
1,0 to 2,2 1,4 to 2,4 2,5

For the purpose of determining and verifying declared noise emission values for drying for washer-dryers in accordance with IECĀ 60704‑3, the values indicated in TableĀ 104 apply.

TableĀ 104

Standard deviations for declaration for drying final results for washer-dryer

Standard deviation (dB)
σP (production) σt (total) σM (reference)
0,7 to 1,0 1,1 to 1,3 1,5
