Above specification we have received from our client for initial hazardous area classification.
What is your opinion about?
All stages still part of initial hazardous area classification, or already more?
I say: more. For initial hazardous area classification the knowledge of possible ignition sources not required. Here it already goes into design stage.
Still we accepted the terminology, and acted accordingly.
Keep up good work!
