適用范圍：This part of IEC 60118 gives recommendations for the measurement of the performancecharacteristics of air-conduction hearing aids of a particular model for production, supply anddelivery quality assurance purposes. The manufacturer will normally assign nominal values.This standard does not relate to mechanical or environmental tests. It should not be used asthe basis for the exchange of information about hearing aid characteristics in general, nor is itintended to be used as a predictor for real-ear performance.Though the number of measurements covered by this standard is limited, it is not intendedthat all measurements described herein shall be made in every case.This second edition now specifies performance requirements. Conformance to the specificationsin this standard is demonstrated only when the result of a measurement, extended bythe actual expanded uncertainty of measurement of the testing laboratory, lies fully within thetolerances specified in this standard extended by the values for Umax given in Table 4.In case of custom-made in-the-ear instruments, the data supplied by the manufacturer appliesonly to the particular hearing aid being tested.
