Scope

1.1 This practice establishes a standard for computing a 99?%/95?% Interlaboratory Detection Estimate (IDE) and provides guidance concerning the appropriate use and application. The calculations involved in this practice can be performed with DQCALC, Microsoft Excel-based software available from ASTM.21.2 The IDE is computed to be the lowest concentration at which there is 90?% confidence that a single measurement from a laboratory selected from the population of qualified laboratories represented in an interlaboratory study will have a true detection probability of at least 95?% and a true nondetection probability of at least 99?% (when measuring a blank sample).1.3 The fundamental assumption of the collaborative study is that the media tested, the concentrations tested, and the protocol followed in the study provide a representative and fair evaluation of the scope and applicability of the test method as written. When properly applied, the IDE procedure ensures that the 99?%/95?% ID
