Certification of products, processes and services is a check or verification carried out by a third party aiming to provide added confidence to both the market and public authorities about the compliance with requirements of products, processes or services.

For the certification to unfold all its advantages, it is essential that the certification body is perceived as a technically competent, impartial and reliable organisation by all those who need to trust in the veracity and value of the certificates it issues (e.g., customers, consumers, shareholders or competent authorities, among others). 

Thus, only accredited product, process or service certification bodies have demonstrated their competence and impartiality to provide a certification service, as they operate in compliance with the requirements established in UNE-EN ISO/IEC 17065 standard.
