AbstractThe common method for rain-leakage testing of windows in North America has been to use a static airpressure difference to simulate the effects of wind and a water-spray- nozzle system to simulate wind-driven rain. A number of test methods are being used that incorporate these essential features but which differ in details of apparatus and test variables. The American Society of Testing and Materials has recently attempted to achieve some degree of uniformity in these methods. The Division of Building Research participated in this activity of the ASTM in two ways. The Division undertook a comparison of the wetting characteristics of several spray-nozzle systems and the apparatus in use at DBR/NRC. The latter apparatus is patterned after that of the Norwegian Building Research Institute and utilizes air-driven water drops. The Division also undertook tests on a number of proprietary windows with some of the spray-nozzle systems and the DBR/NCR apparatus to determine the effect of the method of water application and the wetting rate on the water-leakage performance. This paper reports the results of these investigations.
