design and construction of nonelectrical equipment, intended for
use in explosive atmospheres, protected by the types of protection
constructional safety “c”, control of ignition source “b” and
liquid immersion “k”.
This part of ISO/IEC 80079 supplements and modifies the

The types of ignition protection described in the standard can
be used either on their own or in combination with each other to
