1 Scope
This part six of EN 764 is a Technical Report and as such is a generic document that identifies requirements
for operating instructions which accompany the pressure equipment when it is placed
on the marked. It only provides general statements and thus does not claim to give
presumption of conformity to the essential safety requirements of the Pressure Equipment
Directive 97/23/EC (PED).
Operating instructions contain the necessary safety information covering installation
including assembling, putting into service and maintenance. For specific items of
pressure equipment or assemblies, more detailed requirements on the content of operating
instructions can be found in specific standard series such as EN 13445 “Unfired pressure vessels”, EN 13480 “Industrial piping”, EN 12952 “Water-tube boilers and auxiliary installations”, or EN 12953 “Shell boilers”.
