Failing stresses of glass‐reinforced plastics and of polystyrene were determined at room temperature. It was found that if an initial load of 40% of the short‐term tensile strength of the material is imposed, good agreement exists between the results of accelerated tests and long‐term, fixed load measurements for periods of 10,000 hours for the reinforced plastics.
