Nicely presented

Not really accurate information I would say also a little misleading: "Simple apparatus shall be
clearly identifiable by durable labelling."
16.4 Simple apparatus
Simple apparatus is independent of the equipment protection level. Simple apparatus shall be
clearly identifiable by durable labelling.
IEC 60079-14
Labelling for simple apparatus may be by any party, including the manufacturer or installer,
and may be by any designation marking or code preferred for the installation such that it is
clearly identifiable as simple apparatus.
Additional information to assist in the identification of the simple apparatus such as a
reference to the instrument loop number may also be marked.
