ASTM C773 – 88(2016)
One operator in each laboratory tested ten specimens of each material. They may be formed and matured for the purpose of compression testing, or they may be cut from matured whitew- are by sawing or coredrilling.
Discard any pieces exhibiting cracks or flaws visible to the unaided eye. This test is a c773 of the potential load-bearing usefulness of a ceramic.
ASTM C 773 – 88
NOTE 1—It is desirable to include details of the origin of the specimen and subsequent treatment. Originally published as C — 74 to replace C and C C 5 compressive strength of the specimen, psi or MPa; P 5 total load on the specimen at failure, lbf or N; and A 5 calculated area of the bearing surface of c73 specimen, in.
Precision and Bias 8.
Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being qstm, are shown in the following table: Single-operator component Between-laboratory component 1. Current edition approved Sept. The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen.

Significance and Use 3. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Place an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator. The ends of all specimens shall be ground or lapped to yield plane and parallel faces. A number in parentheses indicates the year of last reapproval. New d773 pads shall be used for each specimen. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.
These faces shall be perpendicular. Ideally, ceramics should be stressed this way in use.
The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows:
