Characterizing the Effect of Weathering Variables Using Accelerated Fractional Factorial Experiments
Atlas Material Testing Technology LLC decided to investigate new approaches to developing weathering methods. The close analogy between manufacturing and weathering processes indicated we might find method development approaches for weathering tests in traditional manufacturing method development. Some approaches widely used in manufacturing let the process itself direct method development rather than committees or individuals. We decided to try one of these approaches and let the weathering process itself direct weathering test method evolution by characterizing the effect of different variables on the weathering process.
Letting the weathering process direct the research and development of new methods seems to represent a viable alternative. Using fractional factorial weathering experiments to characterize weathering variables' effects on materials appears effective for engineering weathering research methods. For certain research efforts, this approach may be quicker, less expensive and more effective than many of the alternatives popular in weathering technology today.
