Electrical and electronic household and office equipment - Measurement of low power consumption
 N EN 50564

Annotation

This European Standard specifies methods of measurement of electrical power consumption and the reporting of the results for a range of electrical and electronic household and office equipment, hereafter referred to as products.

This standard

- addresses issues associated with measuring electrical power, in particular low power (in the order of a few Watts or less), consumed by mains powered products,

- describes in detail the requirements for testing single phase products with a rated input voltage in the range of 100 V a.c. to 250 V a.c. but it may, with some adaptations, also be used with three phase products,

- may also be of assistance in determining the energy efficiency of products in conjunction with other, more specific, product standards.

The value of energy consumed will depend on the operating mode of the product under test, for instance whether the equipment is in an off mode, in a standby mode or in an active mode. This standard does not specify these modes and so it is not possible to use this standard on its own. Instead, it provides a method of measurement with a variety of modes which are defined elsewhere.

This standard does not

- specify safety requirements,

- specify minimum performance requirements,

- set maximum limits on power or energy consumption,

- contain limit values or procedures for verifying compliance with regulatory requirements.
