Ακουστική - Μετρήσεις ηχομόνωσης κτιριακών στοιχείων - Απαιτήσεις για την ακρίβεια των μετρήσεων

@ Lays down procedures for assessing uncertain 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.
