鈥斅犅犅� building elements;
鈥斅犅犅� technical elements (small building elements);
鈥斅犅犅� sound insulation improvement systems.
It is applicable to laboratory test facilities with suppressed radiation from flanking elements and structural isolation between source and receiving rooms.
This document specifies qualification procedures for use when commissioning a new test facility with equipment for sound insulation measurements. It is intended that these procedures be repeated periodically to ensure that there are no issues with the equipment and the test facility.
