If a manufacturer label the product as <Class A>, they do not have any responsibility if the end user is using it in an residential environment with its potential risk for making disturbance?

Independent of the standards, the EMC directive requires marking on typeplate and/or documentation if an equipment is non-residential. 2. Unwilling standards committees have been "reluctant" in including the definitions in written in their standards. CISPR I has been notorious in these for years, by not even defining Class A for immunity (CISPR 24). There are ample standards and EC documents giving an appropriate definitions, in general something like: If it is predominantly used for households or is connected to a residentially used power newtwork the equipment will be residential or often said "Class B". If connected to a private power network then it should be Industrial or "Class A". One standard that comes to mind that gives a good description including examples is EN 61326-1:2013. An EC document TC210/Sec0515/INF from 2007 addresses the topic in full and includes the recommendation to include a common definition in all harmonized standards.

For reference, the FCC classifies products into consumer (Class B) and non-consumer (Class A) categories. In Europe the manufacturer has a similar responsibility to make a product that meets the EMC requirements appropriate for the intended use of the product. For some products it is more or less up to the end user to determine if a Class A or Class B compliant product is appropriate. You will find the Class A warning statement in the EN 55032 standard, Clause 7. Class A equipment shall have the following warning in the instructions for use, to inform the user of the risk of operating this equipment in a residential environment: W arning: This equipment is compliant with Class A of CISPR 32. In a residential environment this equipment may cause radio interference. Bill Stumpf - Lab / Technical Manager D.L.S.

"Equipment intended primarily for use in a residential environment shall meet the class B limits. All other equipment shall comply with the Class A limits." I am unable to locate a definition for residential environment in the standard. Does anyone know of an official definition? Would sports stadia, theatres, hospitals, commercial industrial estates located in residential housing be included in residential environments? If the product is Class A, is the warning notice still required? "Warning. This is a Class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures." This used to be a requirement in EN 55022.
