This five-volume set lays down the theoretical basis for the specification and testing of international standards related to product design. Manufactured product has to be designed to withstand the effects of the environmental factors (temperature, humidity) and also the effects of externally imposed mechanical shocks and vibrations, which might result in fatigue and other damage. This has given rise to the concept of the tailorization of product, leading to the tailorization of tests. Tailorization implies not only an understanding of the effects of the environment, but also presupposes proper understanding of the mechanical systems subjected to mechanical loads, and knowledge of the most frequent failure modes. This is implemented by the use of a simple theoretical model, enabling the effects of shocks and vibrations to be assessed, and the drafting of specifications, pre-sizing calculations and the establishment of rules for analysis and definitions of tests to be developed. Throughout, the theoretical treatments are placed in the context of the real environment and of laboratory tests - essential for the development of standards. The series culminates, in Volume V, in the development of specifications.
