1 Scope
This part of ISO/IEC 80079 specifies the basic method and requirements for design, construction, testing and
marking of non-electrical Ex equipment , Ex Components , protective systems, devices and assemblies of these products that have their own
potential ignition sources and are intended for use in explosive atmospheres.
Hand tools and manually operated equipment without energy storage are excluded from the scope of this standard. This standard
does not address the safety of static autonomous process equipment when it is not part of equipment referred to in this standard.
NOTE 1 Static autonomous process equipment includes items such as tanks, vessels, fixed pipework and hand operated valves which
do not have their own source of energy that could create a potential ignition source during operation.
This standard does not specify requirements for safety, other than those directly
related to the risk of ignition which may then lead to an explosion. The standard
atmospheric conditions (relating to the explosion characteristics of the atmosphere)
under which it may be assumed that equipment can be operated are:
• temperature -20 °C to +60 °C;
• pressure 80 kPa (0,8 ba...
