ASTM C773 – 88(2016)

If the contact block is cracked during testing, it shall be replaced. Single-operator component Between-laboratory component 1.

Ideally, ceramics should be stressed this way in use. One operator in each laboratory tested ten specimens of each material. C 5 compressive strength of the specimen, psi or MPa; P ast, total load on the specimen at failure, lbf or N; and A 5 calculated area of the bearing surface of the specimen, in. This test is a measure of the potential load-bearing usefulness of a ceramic. These faces shall be perpendicular.


Precision and Bias 8. Last previous edition C — 88 Originally published as C — 74 to replace C and C A number in parentheses indicates the year of last reapproval.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Current edition approved Sept.

NOTE 1—It is desirable to include ast, of the origin of the specimen and subsequent treatment. The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen.

New cushion pads shall be used for each specimen.

They may be formed and matured for d773 purpose of compression testing, or they may be cut from matured whitew- are by sawing or coredrilling. Place an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator. Enviado por Thamyres flag Denunciar.

The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows: Significance and Use 3.


ASTM C 773 – 88

The ends of all specimens shall be ground or lapped to yield plane and parallel faces. 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.

C — 88 Reapproved Standard Test Method for Compressive Crushing Strength of Fired Whiteware Materials1 This standard is issued under the fixed designation C ; the number immediately following the astj indicates the year of original c737 or, in the case of revision, the year of last revision.

Discard any pieces exhibiting cracks or flaws visible to the unaided eye. Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being tested, are shown in the following table:
