Introduction
This document has been produced to assist designers, manufacturers and other interested parties to use
harmonized terms and definitions (vocabulary) for equipment and protective systems intended for use
in potentially explosive atmospheres. It describes the vocabulary to be used to give all standards in this
area an overall uniformity of terminology. Throughout this document, the only hazard considered is the
explosion of an explosive atmosphere.

This document specifies terms and definitions (vocabulary) to be used in suitable standards dealing with
equipment and protective systems intended for use in potentially explosive atmospheres within the
scope of Directive 2014/34/EU.
NOTE Terms and definitions avoid misunderstandings that are important in relation to the essential health
and safety requirements of Directive 2014/34/EU.
