What you should know
before contacting FTZÚ

Certification of the equipment and protective systems intended for use in potentially explosive atmospheres:

  • Equipment group and category. All equipment groups and categories are given in the table below.

  • Standards according to is product designed.List of the standards

  • Type of protection for electrical and non-electrical equipment. Electrical and non-electrical equipment shall meet standard EN IEC 60079-0 and one or more standards that supplement or modify it. Summary of the types of protection and associated standards are given below.

  • I am interested in getting type or unit certificate. It is necessary to deal with quality system QAN (for ATEX) eventually QAR (for IECEx) in case of type certification.
    QAN (for ATEX) eventually QAR (for IECEx) in case of type certification..

  • I am interested in offering product inside EU or eventually outside EU.

  • Either you have enough information about product or you can’t handle with something, do not hesitate to contact us.
