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:
