  • Hello Stanislav,
    within the ATEX directive, the designation ‘h’ for non-electrical devices has existed since around 2016. Manufacturers had some transition time available (until October 2019) to issue/update their Declarations of Conformity. The Protection Principle "EX h" makes reference to "mechanical equipment".

  • Hello Stephan,
    thank you for answer.
    It is the same / similar like c - safe construction, b - monitoring of ignition sources, k - immersion (liquid) protection?
