DESCRIPTION
This standard BS EN 60704-2-14:2013+A11:2015 Household and similar electrical appliances. Test code for the determination of airborne acoustical noise is classified in these ICS categories:
  • 97.040.30 Domestic refrigerating appliances
  • 17.140.20 Noise emitted by machines and equipment

This clause of Part 1 is applicable except as follows:

1.1 Scope

1.1.1 General

Addition:

These particular requirements apply to refrigerators, frozen-food storage cabinets and food freezers (fitted with their accessories) for household and similar use, supplied from the mains or from batteries.

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 refrigerators, frozen-food storage cabinets and food freezers.

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 refrigerator, frozen-food storage cabinet or food freezer under test fulfils the requirements specified in 1.3 of ISO 3743‑1 and ISO 3743‑2 .

1.2 Object

Addition:

These described methods are specified for appliances without an operator present.

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

NOTE 101

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 indicated in Table 101:
