Part 1 presents and analyzes relevant information data on applicable operational environments, candidate test methods, and previously used simulation/testing techniques. Appropriate corrective action is recommended to circumvent knowledge voids and/or test method deficiencies. A realistic and cost-effective durability evaluation criteria is presented in Part 2 for monolithic stretched acrylic, coated monolithic polycarbonate, and acrylic faced/polycarbonate laminate configurations. 收起
