Site Hose Tests

Spraying water in a prescribed way at the joints in the system is a quick and easy check on whether the system is vulnerable to leakage. It does not confirm the performance in a formal way however – that is done using the Static Water Penetration Test where water is sprayed over the whole specimen while the inside pressure is reduced by means of a chamber.

The Hose Test, either AAMA 501.2-09 or CWCT Section 9 (for both of which we are accredited), should be employed periodically during construction as a check on workmanship (the design having been validated in the laboratory). It is sometimes used as a basis for accepting the curtain wall at the end of the project.

The alternative, Site Chamber Tests, have fallen out of favour because they are complicated to set up (requiring the construction of a test chamber on site over usually two floors), and because the on-site Air Infiltration test is now discouraged for continuous systems where air travelling laterally within the system cannot be separated from air coming from the outside.
