statistical treatment of data measued during inspection
statistical treatment of data measued during inspection
(OP)
Hello,
When the dimension of shell or head are inspected, measurements are done at the several points. Or several measurements are done at each point for more precise inspection.
Does ASME Code require statistical managenment for these data? For example, standard deviation, uncertainty of measurement,type A evalution etc.
Is there any construction of boiler and pressure vessel which require statistical treatment?
Thank you.
PS : I don't think normally the boiler and pressure vessure vessel construction code require statistical treatment. But I want to make sure that because some standard for AIA(Authorized Inspection Agency)require statistical managenment for acquired data during inspection.

BSR/ASME PCC-3-200x, Inspection Planning Using Risk Based
Methods (new standard)
Provides information on using risk analysis to develop and plan an effective inspection strategy. Inspection planning is a systematic process that begins with identification of facilities or equipment and culminates in an inspection plan. Both the probability of failure and the consequence of failure should be evaluated by considering all credible
damage mechanisms that could be expected to affect the facilities or equipment. In addition, failure scenarios based on each credible damage mechanism should be developed and considered
