OFI CERT lists all currently valid, as well as withdrawn, certificates as a list in the section on voluntary services (OFI CERT, GRIS, ENplus). Any interested parties and the general public are thus able to check whether a certificate issued by OFI CERT continues to be valid. As a rule, the certificates can be requested either from the manufacturer or from OFI CERT (This email address is being protected from spambots. You need JavaScript enabled to view it.).
