Water tightness test
Instrumentation for the measurement of creep and shrinkage as well as thermal and moisture movement of building materials. An Atlas-Weather-ometer (Model Cl 35) is available for accelerated weathering tests on building materials. The equipment can be used to provide exposure to radiation from a Xenon lamp under accurately controlled conditions of temperature and humidity. It can also be programmed for alternating cycles of light and darkness, with or without water spray. The equipment is designed to produce uniform irradiance on the face of the test specimen under controlled specimen temperature and relative humidity. It can be used for acceptance testing, product control, quality control, research and development.
