This article reviews the current state of the art of
weathering test design, It describes the primary environmental and procedural variables involved
in the design of a weathering test. The relationship between the environmental variables and the
current techniques available to accelerate the degradation process either outdoors or in the
laboratory is discussed. Primary environmental variables include light, heat and
moisture;procedural variables include exposure cycle,exposure time and test initiation, Both
laboratory accelerated and outdoor weathering procedures are addressed in the paper. Each of the
variables is briefly examined and examples of practical solutions given. The most commonly used
exposure racks, boxes and cabinets as well as laboratory accelerated testing devices and
instrumentation for monitoring and reporting climatological data are described, (C) 2000
