Who is responsible for writing the schedule?
The areas to be tested and the level of
strip down needed to achieve this should be identified and listed,
preferably by the original designer, but advice may also be sought
from Inspection Bodies (IBs) or other experts who may have the
competence to predict areas that may be subject to fatigue failures.
The schedule should contain instructions
regarding the intervals at which this NDE needs to be carried out. Again this should preferably
be (or have been) drawn up by the original designer, but advice may
also be sought from IBs or others who may have the competence.
It is fair to say that experience forms a certain part in all of
this, but anyone developing a schedule will need to understand where
fatigue might occur regarding the particular device, and in what
timescale it might occur.
There will certainly be some instances where basic fatigue
calculation will also be required. Anyone working out such
calculations should be certain that he is suitably competent, to
carry out any calculations required.
