The work carried out at Picatinny Arsenal on the weathering of plastics over the lat 15 years is briefly described. Although the perid of work was 15 years, individual systems were exposed for only three years. The need for running parallel tests on materials stored indoors for the three years is pointed out as a means of separating the effects of daging from weathering. Also brielfy discussed is the influence which the test method chosen can have on the judgment reached. The requirements of the application are as important as the inherent durability of the material. Improved compounds are becoming available and complete reporting of both favorable and unfavorable resuts is urged as a means of lending guidance in the search for still better compounds.
