No.
Reason:
The classification under the PED is based on PS in normal or foreseeable operating conditions.
When the manufacturer classes an explosion as an incident, rather than as operation as intended, the explosion pressure shall not determine the classification according to the PED.
When an explosion is considered included as part of the intended operation of the equipment, if the resultant pressure PS is greater than 0,5 bar then the equipment is covered by the PED.

Examples of such equipment could be e.g. grain silos.
