DIN EN ISO 10140-5:2014-09

This part of ISO 10140 specifies laboratory test facilities and equipment for sound insulation measurements of building elements, such as components and materials, building elements, technical elements (small building elements), sound insulation improvement systems. This document 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. The test standard is directed at test laboratories with acoustic test facilities. With respect to DIN EN ISO 10140-5:2010, the artificial rain production and standard reference test specimens have been added for the purposes of quality control and to check the reproducibility of laboratory rain sound measurements in different laboratories. The document replaces the requirements for laboratories and test facilities in DIN EN ISO 140-18:2007. The committee responsible for this standard is NA 062-02-31 AA "Schalldämmung und Schallabsorption, Messung und Bewertung" ("Sound reduction and sound absorption; measurement and evaluation") at DIN.
