New edition of Eurachem/CITAC guide on measurement uncertainty arising from sampling

The second edition of the Eurachem/CITAC Guide on measurement uncertainty arising from sampling (UfS) has recently been published [1]. It has been updated to explain how several new research ideas can be used to improve the way that we estimate and express UfS. The Guide considers the whole measurement process, which usually begins at the point where a primary sample is taken. It retains the basic structure of the first edition, describing the estimation of UfS by both empirical and modelling approaches, and includes six worked examples across several application sectors, including food, animal feed, soil and water.
