ASTM's glass and ceramic standards are instrumental in specifying, testing, and evaluating the chemical, physical, and mechanical properties of various materials and products made of glass, ceramic, or clay. Vickers hardness of ceramics usually decreases with increasing indentation size or indentation force, as shown in Fig. 1. The trend is known as the indentation size effect (ISE). Hardness approaches a plateau constant hardness at sufficiently large indentation size or forces.loads that are needed to achieve a constant hardness vary with the ceramic. The test force specified in this standard is intended to be sufficiently large that hardness is either close to or near the plateau, but not so large as to introduce excessive cracking. A comprehensive characterization of the ISE is recommendedThis test method covers the determination of tensile creep strain, creep strain rate, and creep time-to-failure for advanced monolithic ceramics at elevated temperatures, typically between 1073 and 2073 K.

ASTM E10: This standard covers Brinell hardness testing in metallic samples. ASTM E18: This standard includes the various ways that Rockwell hardness can be measured by standard methods, specifically for metallic materials. ASTM E384: This standard is for hardness testing on a micro-scale, and therefore includes the Vickers and Knoop hardness . 1.1 This test method covers the determination of the Vickers indentation hardness of advanced ceramics. 1.2 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 . 5.1 This test is intended to assess the mechanical integrity, failure modes, and practical adhesion strength of a specific hard ceramic coating on a given metal or ceramic substrate. The test method does not measure the fundamental “adhesion strength” of the bond between the coating and the substrate. Rather, the test method gives a quantitative .Referenced Documents 2.1 ASTM Standards:2 1 These test methods are under the jurisdiction of ASTM Committee E28 on Mechanical Testing and is the direct responsibility of Subcommittee E28.06 on Indentation Hardness Testing. 2 For referenced ASTM standards, visit the ASTM website, www.astm.org, or Current edition approved April 1, 2017.
1.1 This test method covers laboratory procedures for determining the scratch hardness of the surfaces of solid materials. Within certain limitations, as described in this guide, this test method is applicable to metals, ceramics, polymers, and coated surfaces.
