Leslie R Pendrill

Adj Prof Leslie R Pendrill, B. Sc. Physics, Ph. D. Atomic Physics, University of Reading, England, in 1975 and 1978, respectively.

Adjunct professor at Uppsala University, Graduate School Advanced Instrumentation and Measurement Technology, 2006 - 2008.

Prof. Pendrill was R & D Director at Measurement Technology Division and the National Metrology Institute of SP at BorĂ¥s from 1985 - 2012.

He plays a leading role, nationally and internationally, including Chairman 2009-12 for EURAMET (, the European association of national metrology institutes in Europe.

He is currently Chair of ISO/TC12 Quantities & units. Better measurement leads to better products and health. Therefore he develops new quality-assured measurement methods in which man is the main actor: for example, measuring perceived comfort, etc., as well as optimized measurement uncertainty, where the effects of measurement are weighed against the effects of product evaluations. The concept of Man as a Measurement Instrument with Rasch analysis is allowing separate estimates in human-based observations of person sensitivity and item challenge/quality. This in turn enables proper treatment of qualitative data; reduced measurement uncertainty; and opportunities to establish metrological references for comparability. Optimized uncertainty enters into conformity assessment and by extension to standardisation and regulation.
