Abstract: Proftest SYKE carried out the proficiency test for analysis of oil hydrocarbons from water and soil in October 2012. One artificial sample and one surface water sample and one soil sample for the determination of oil hydrocarbons were distributed. In total, 18 laboratories participated in the PT. Either the calculated concentration or the robust mean value was chosen to be the assigned value for the measurement. The performance of the participants was evaluated by using z scores. In this proficiency test 81 % of the results were satisfactory when the deviation of 20–40 % from the assigned value was accepted.
