In order to assess the repeatability of in-duct sound power level measurements taken by using the procedures of the Draft International Standard DIS 5136.2, a programme of tests was conducted by several European laboratories. The test programme consisted of noise measurements on two fans, selected as being typical of those in general use in ventilation systems, which were circulated to the participating laboratories. This report presents the results of the test programme and considers modifications to the Draft International Standard which may be required to achieve increased accuracy and repeatability. A synthesis report is published full-size with the same title.
