Specification development

This volume is concerned with the presentation of specification development in accordance with the principle of tailoring. Extreme response and the fatigue damage spectra are defined for each type of stress (sinusoidal vibration, swept sine, shock, random vibration, etc). The process for establishing a specification from the life cycle profile of the equipment is then detailed, taking account of the uncertainty factor, designed to cover uncertainties related to the real environment and mechanical strength ; and the test factor, which takes account of the number of tests performed to demonstrate the resistance of the equipment.
