The original article on scalable accuracy which laid the groundwork for the concept was published in the March April 2011 issue of the Inspectioneering Journal, entitled Scalable Accuracy, Key Roles of Risk Based Inspection and Fitness for Service, Equipment Life-Cycle Management Process. This article is reprinted immediately following this article for ease of reference. The two examples touched upon in the original article were the fitness for service approach as represented by the joint API ASME standard, API 579-1/ASME FFS-1 Fitness for Service Standard and the API Recommended Practice 581, representing the specific API RBI technology. Another area demonstrating scalable accuracy is the selection of inspection strategies based on risk. I will cover this in the next article on scalable accuracy with some discussion on considering the amount of scatter in the selection of NDE and in developing the overall inspection strategy for a piece of equipment both in standalone and risk driven terms. Let's think of scalable accuracy for various practices in terms of effective equipment lifecycle management. We welcome other views, comments, etc. The concept may be difficult to grasp for some so we will elaborate a bit more.
