This section of IEC 60704 outlines the procedures for determining and verifying the declared noise emission values of household and similar appliances.
It is applicable to all categories of household and similar electrical appliances as specified in IEC 60704-1 and IEC 60704-2, which address specific requirements for particular types of appliances.
The standard pertains to appliances produced in quantities (in series, batches, or lots) that adhere to the same technical specifications and are characterized by the same labeled noise emission values.
This part of IEC 60704:
- Defines “declaration” to encompass all methods of providing information about noise emission values to potential users (consumers) of the appliances, including labels, brochures, advertisements, and commercial or technical information documents.
- Addresses declarations for appliances produced in mass production with the same declared value for the entire lot (batch).
- Specifies a straightforward statistical method for verifying the declared values by examining a sample of just three appliances.
