The European Centre for
Mathematics and Statistics in Metrology


SP Sveriges Tekniska Forskningsinstitut AB (SP Technical Research Institute of Sweden AB) is owned by RISE Research Institutes of Sweden Holding AB under the Ministry of Industry. SP is the national institute for technical evaluation, research, testing, certification, metrology and calibration and is working closely with large and small companies, universities, institutes of technology and other organisations. SP's activities cover a wide technical range, with about 30 technology areas organised in eight inter-working technical departments. SP has over 1000 co-workers who base SP’s services on competence, efficiency, impartiality and international acceptance. SP's headquarters are located in Borås, close to Gothenburg on the west coast of Sweden.
SP is a national metrology institute, with responsibility for maintaining and developing the primary measurement standards of the SI (metre, kilogram, second, etc), and associated measurement methods and techniques. The Swedish National Metrology Programme is owned by VINNOVA, the Swedish Governmental Agency for Innovation Systems. SP is Past Chair of EURAMET (, the association of national metrology institutes in Europe. SP also conducts research, testing and certification in a wide range of areas related to analytical chemistry and materials technology.
Measurement uncertainty can lead to certain risks of incorrect decisions when attempting to answer questions about the entity, such as are there significant differences between two sets of measurement results or is the test result inside or outside entity specifications. In the past decade or so, one has sought to go beyond the certain arbitrariness of percentage risk in traditional statistical significance testing, by establishing optimal cost/benefit, specifically the measurement uncertainty required to achieve the optimal balance between cost of measurement and cost of incorrect conclusions. Firstly developed in analytical chemistry, this 'fitness for purpose' approach is being successively applied to diverse fields of application such as in measurement and conformity assessment of the utilities (energy, water etc), vehicle chassis manufacture, environmental emissions and pre-packaged goods.

Leslie Pendrill

has been the Head of Research of the Measurement Division at the SP Technical Research Institute of Sweden since 1985. His research work is concerned with fundamental metrology, in particular optoelectronic, laser, length, and mass measurements, while his applied metrology activities include optimised measurement uncertainty studies and the measurement of perception. He is actively involved in several international metrology activities, holding leading roles such as the 2009-2012 Chair of the European Association of National Metrology Institutes (EURAMET).
