Site Hose Testing for Curtain Walling in accordance with the CWCT 1995 Test Methods for Building Envelopes 2005, AAMA 501-94 and BS 5368 Standards.

Hose testing is intended for the testing of permanently sealed joints. The high pressure water spray should not dislodge gaskets or wet applied sealants unless they have been poorly installed or not been allowed to cure. Water will be forced through small gaps in these types of seals and will find its way through unsealed joints between framing components. Hose testing is not suitable, in its unmodified form, for use on open joints even if these are baffled as the flow of water from the nozzle will overwhelm most open joints or joints that are intended to open. If the hose test is used on open or opening joints then the normal procedure is to reduce the nozzle pressure. However the spray bar test is more applicable for this type of joint.
