1.1 This test method covers the determination of a materials resistance to damage by chipping or flaking. Fig. 1 shows the common configuration used for testing. Several indices of the resistance to edge chipping are allowed by this Test Method. This Test Method is limited to homogeneous monolithic ceramics with flat surfaces and straight sharp or chamfered edges. This Test Method is primarily intended to be used with materials that are linearly elastic to fracture, but may have some utility to brittle materials that exhibit some nonlinearity. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Edge chipping is a common problem with brittel materials. A method to quantify and measure it is needed.
