A product Family standard is used to guide the manufacturer or test facility on which tests to run for a particular family of products. It is typically an overview of the required emissions and/or immunity tests required to comply with the requirements in countries in which the products will be marketed. The product family standard will include the reference to Basic Standards or Phenomena standards which will contain the test methods and procedures along with details of test apparatus and test set-up. Although a basic standard may give guidance on the choice of levels and severity, they generally do not give the prescribed limits or criteria for compliance. The limits and test levels and criteria for compliance are usually indicated within the product family standard.


Product family standards are easy to identify, such standards will mention "Product Family standard for X" directly in the title. The precedence of harmonized standards follows an informal ranking based on the type of standard;
  • Product Specific
  • Product Family
  • Generic or Product Environment
  • Basic (or Phenomenon)
 

The most commonly applied standards are Product Family standards. Very few product specific  standards are available. Basic standards, although on the list, are generally not applied directly, but via reference from one of the other three types. Exceptions to this include examples such as power line harmonics and voltage fluctuation and flicker, as these basic standards are referenced in the Official Journal directly.


The applicable versions are listed on EMC Directive list of harmonized standards published on the European Commission web site.

 Europe has a series of standards prefixed “EN” - European Norm. These are written by the European Committee for Standardization (CEN), the European Committee for Electrotechnical Standardization (CENELEC), and the European Telecommunications Standards Institute (ETSI). The vast majority of ENs that are relevant for the EMC Directive are produced by CENELEC.


Harmonized standards are ENs produced by CEN, CENELEC or ETSI, following a mandate issued by the European Commission, for use with one or more directives. The lists of harmonized standards suitable for each Directive are published from time to time in an official publication called the Official Journal of the European Union, often referred to as “the Official Journal” or “the OJ”.


The date of publication (dop) for an EN standard is commonly 6 months from the date of availability (dav). The date the standard becomes mandatory is its date of withdrawal (DOW).


All European Standards are shaped by consensus among enterprises, public authorities, consumers, and trade unions, through a consultation process organized by independent, recognized standardization bodies at national, European and international level.CENELEC Guide 25 “Guide on the use of Standards for the implementation of the EMC Directive” is available as guidance for the application of harmonised standards:
