Determination of Proof Test Level for Test-Degradable Components.
Abstract
Conventional proof testing practice yields a component population with an initial reliability of 1.0, when viewed from the standpoint of stress/strength interference theory. The proof test is reviewed for the case of test-degradable components. Methodology is developed which allows the determination of an optimum test level. This theory is applied to filament-wound pressure vessels, and it is found that test- degradable components require a proof test usage entirely different from that followed with components not subject to this degradation.
