Scope

Due to the impact of randomness and systemicity, there is uncertainty in the acoustic measurement methods described in the relevant parts of GB/T 19889. This part specifies the method for evaluating this uncertainty. This standard provides guidelines for: - determination of repetition rate r and reproducibility rate R; - verification of repetition rate r and reproducibility rate R for different measurement arrangements in the same laboratory and comparative tests in different laboratories . ——The application of repetition rate r and reproduction rate R in practical work. The repetition rate and reproduction rate of GB/T19889 Part 3, Part 4, Part 6, Part 7 and ISO 140-8 test methods are temporarily given in Appendix A. Note: No data are currently available on the repeatability and reproducibility of the ISO 140-5 test method.
