  • Weathering testing system
    Patent number: 4957011
    Abstract: A testing system for determining accelerated weathering characteristics of various items such as fabrics and paint samples. Rack means are provided for carrying samples to be tested. A source of irradiation of the inner-facing surfaces of the samples carried on the rack is also provided, along with a blower system for directing a stream of air through the rack. In accordance with this invention, a generally conical member is positioned in the stream of air to redirect the stream outwardly in a generally conical flow path. The generally conical flow path is positioned by the conical member to flow across the inner-facing surfaces of the samples carried on the rack.
