New Practice for Uncertainty Estimation of Quantitative Measurements in the Analysis of Seized-Drugs

1. Scope

This standard provides minimum requirements for the estimation of uncertainty for quantitative measurements in the analysis of seized-drugs. In this context, uncertainty encompasses an assessment of the range of plausible measured values when applied in quantitative measurements.


Uncertainty; Seized-drugs; quantitative measurements


In forensic science, it is critical to assess/estimate the uncertainty associated with measurements and disclose the existing limitations regarding these measurements. Forensic laboratories oversee and achieve compliance for measurement uncertainty through training, established operating procedures, and documentation. ASTM E2764, Standard Practice for Uncertainty Assessment in the Context of Seized-Drug, expired in 2020. This new standard provides minimum criteria for the estimation of uncertainty for quantitative measurements and incorporates elements from E2764, as it relates to measurements in drug analysis.

The title and scope are in draft form and are under development within this ASTM Committee.
