ALSO NUMBERED AS BS EN 20140 PT2 Specifies procedures for assessing uncertainty in acoustical measurements. Gives guidelines for: application of repeatability values r and reproducibility values R in practice; determination of the repeatability value r and the reproducibility value R; verification of repeatability values r and reproducibility values R for different measurement arrangements in one laboratory and for comparisons between different laboratories. Also includes detailed annexes and tables.
