Certification systems
A certification system is a system by which a product, person or system is certified. For example, there are certificates for the voluntary quality marks such as BENOR, ATG or KEYMARK and certificates for the mandatory CE marking (this only concerns CE marking: AVCP systems 1, 1+ or 2+).
By clicking on a specific certification system, a list is shown of companies that have a valid BCCA certificate of the selected system. When selecting a company, a list of all the BCCA certificates issued to that company is then displayed. If made available, the certificate itself can be displayed.
The BCCA website is the only reference for valid certificates published under the responsibility of BCCA
