The first step is to determine whether your product can bear the CE mark or not. Not all products must bear the CE marking, only products that fall under at least one of the CE marking instructions. There are more than 20 product directives and regulations covering a wide range of products. These products include but are not limited to, electrical equipment, machinery, medical equipment, toys, pressure equipment, PPE, wireless devices, and construction products.

Each policy has a slightly different method of demonstrating compliance. This usually depends on the product classification and its intended use. Each lead has a number of "essential requirements" that the product must meet. To know more about UKCA certification, you can also check out this source: what is ukca certification & its marking process via Blue Dice Solutions.


Compliance with these basic requirements can best be demonstrated by meeting the requirements of the applicable "harmonious European standard" (standard), also known as hEN. Standards can provide a presumption of conformity with important requirements of applicable law. However, note that the use of standards is usually voluntary. 

The CE marking process is always a self-declaration process, but you may need to involve a third party. This is stated in "System Verification" and varies from policy to policy. For some products (such as invasive medical devices or fire alarm systems), the involvement of an authorized third party may be required to some extent.

This usually involves some type of assessment and/or testing. This often includes ensuring that the requirements of the applicable harmonization standards identified in step 2 are met.

It is important to prepare technical documentation for the product or product range. This information should cover every aspect of compliance and possibly include details about product design, development, and production.
