Acoustics; Measurement of sound insulation in buildings and of building elements; Part II : Statement of precision requirements
Описание (англ.):
Lays down procedures for assessing uncertainty in the acoustical measurements described in ISO 140, parts 3 to 8, due to non-systematic influences. Results may be used for checking different measuring arrangements in one laboratory and for comparing such conditions in different laboratories or in field situations. Values obtained are not intended for use in test reports as statement of accuracy of actual measurements.
