Description of BS EN IEC 60704-2-16:2019+A11:2020 2020

This clause of Part 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 ISO 3743‑1, ISO 3743‑2 and ISO 3744 can be used for measuring noise emitted by washer-dryers.

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 washer-dryers under test fulfils the requirements specified in 1.2 of ISO 3743‑1:2010 and 1.3 of ISO 3743‑2:1994.

1.2 Object

Addition:

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

NOTE 101 For determining and verifying noise emission values declared in product specifications, see IEC 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 Table 101 and 102.

Table 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

Table 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 IEC 60704‑3, the values indicated in Table 103 apply.

Table 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 IEC 60704‑3, the values indicated in Table 104 apply.

Table 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
