Specifies procedures for assessing the uncertainty in acoustic measurements. Gives guidelines for: application of repeatability values r and reproducibility values R in practice; determination of the repeatability value r and the reproducibility values R; verification of repeatability values r and reproducibility value R for different measurement arrangements in one laboratory and for comparisons between different laboratories. Also includes detailed annexes and tables. ALSO NUMBERED BS 2750: PART 2: 1993
