API MPMS Chapter 13.1 (R2016) PDF
Designed to help those who make measurement of bulk oil quantities improve the value of their result statement by making proper estimates of the uncertainty of probable error involved in measurements. Includes Errata (July 2013).
This chapter covers the basic concepts involved in estimating errors by statistical techniques and ensuring that results are quoted in the most meaningful way. The statistical procedures that should be followed in estimating a true quantity from one or more measurements and in deriving the range of uncertainty of the results are discussed.
Sources of error are examined and examples are provided showing how a statement of the overall uncertainty in completed measurements is derived.
The subsequent sections (in preparation at the time this section was published) of Chapter 13 will deal with the application of the concepts discussed in Section I to various methods for bulk oil measurement widely used in the petroleum industry. Chapter 13.1 is a reference document explaining theory and the application of statistical procedures whereas subsequent sections will provide statistical equations and typical examples for various types of measurement.
