Complex Product VT Rating Bid Review Task Group

CHAIRS CONTACT INFORMATION

Project Objective

Develop a methodology for determining Visible Transmittance (VT) for products with complex glazings. The project will seek to analyze a range of complex products using both integrating sphere testing and ray-tracing simulation and compare the methodologies. This project will research, develop, construct and validate a test methodology to determine the VT of complex products. This methodology will be evaluated against current techniques as well as ray-tracing simulation techniques to determine the appropriate ratings procedures for complex products. Source spectrum will be monitored throughout research project and reported.
