What Are Harmonized Standards And How Do They Affect the CE Mark?



Harmonized standards are technical specifications set by European agencies that, when aligned with a product directive, set compliance standards for a given product. Harmonized standards are voluntary, but following the right harmonized standard is the best way to obtain the CE Mark.

Meeting the requirements of an applicable harmonized standard gives your product a “presumption of conformity” to the essential requirements for the CE Mark. In other words, if you can prove your product meets the harmonized standard, you can demonstrate compliance with the relevant product directive.

Harmonized standards are developed and managed by three European standards organizations:

     European Committee for Standardization (CEN) - consolidates national standardization bodies for 34 European countries and creates European Standards (ENs) and other technical documents for a wide range of products
     European Committee for Electrotechnical Standardization (CENELEC) - produces ENs and Harmonization Documents (HDs) for electrical engineering products
     European Telecommunications Standards Institute (ETSI) - produces global standards for information and telecom technologies, including internet, mobile, radio, fixes, and broadcast technology.

How Do Harmonized Standards Affect CE Marking?

The CE Mark is required for certain types of products to enter any country in the European Economic Area (EAA), which includes European Union (EU) countries, as well as Iceland, Norway, and Liechtenstein. CE Marking is part of the New Approach legislation that holds all companies accountable for the same product standards; the CE Mark signifies the product meets safety, health, and environmental protection standards.

As companies develop products that will be sold in the EU or the larger EAA, they look to the relevant CE standards for specific technical requirements. These requirements, which are often altered and refined through legislation, are best summarized by harmonized standards.

There are harmonized standards for each product directive associated with the CE Mark, including:

     Low Voltage Directive (LVD) — 2014/35/EU
     Machinery Directive (MD) — 2006/42/EC
     EMC Directive (EMC) — 2014/30/EU
     Medical Device Directive (MDD) — 93/42/EEC
     Radio Equipment Directive (RED) — 2014/53/EU
     Restriction of Hazardous Substances Directive (RoHS) — 2011/65/EU

The requirements for each product type—including radio equipment, machinery, medical devices, and more—are only legally binding once they’re entered into the European Commission’s Official Journal. However, harmonized standards are an easy way to see how regulations have changed over time and what standards were replaced by new versions.

Depending on what the product is and how it will be used, standards and processes will vary among directives. This includes:

     The method of demonstrating conformity
     The “essential requirements” for design and manufacturing
     The applicable Conformity Assessment Procedure modules
     The number of applicable harmonized standards

The level of risk may also affect the CE Marking process. Products with minimal risk can be self-certified by preparing a Declaration of Conformity and affixing the CE Marking to the product. Products with greater risk need to be independently certified by a “Notified Body,” a.k.a. an independent test lab in a member state of the European Union. Consult a compliance professional if you have questions about the level of risk associated with your product.
