ASTM C 1576 (C-1576) determines the slow crack growth (SCG) parameters of advanced ceramics by using constant stress flexural testing in which time to failure of flexure test specimens is determined in four-point flexure as a function of constant applied stress in a given environment at ambient temperature. In addition, test specimen fabrication methods, test stress levels, data collection and analysis, and reporting procedures are addressed. The decrease in time to failure with increasing applied stress in a specified environment is the basis of this test method that enables the evaluation of slow crack growth parameters of a material.
Universal Test Machines with accurate and response load control capabilities are required for ASTM C1576. ASTM C1576 fixture requirements include Semiarticulating and Fully Articulating Four-Point Fixtures - both of them available from TestResources. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
