- Scope
- This part of ISO 140 specifies procedures for assessing the uncertainty in the acoustical measurements described in ISO 140-3 to ISO 140-9 due to random and systematic influences. It gives guidelines for — 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; — application of repeatability values r and reproducibility values R in practice. Tentative repeatability values and reproducibility values of the test methods according to ISO 140-3, ISO 140-4 and ISO 140-6 to ISO 140-8 are given in annex A. NOTE 1 At present no data are available for ISO 140-5 and ISO 140-9.
