They may be formed and matured for the purpose of compression testing, or they may be aztm from matured whitew- are by sawing or coredrilling. Single-operator component Between-laboratory component 1.

Place an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator.

If the contact block is cracked during testing, it shall be replaced.

C 5 compressive strength of the specimen, psi or MPa; P 5 total load on the specimen at failure, lbf or N; and A c7773 calculated area of the bearing surface of the specimen, in. Ideally, ceramics should be stressed this way in use. Last previous edition C — 88 It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine asym applica- bility of regulatory limitations prior to use.

This test is a measure of the potential load-bearing usefulness of a ceramic. Significance and Use 3.

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 designation indicates the year of original adoption or, in the case of revision, the year of last revision.

Originally published as C — 74 to replace C and C The ends of all specimens shall be ground or lapped to yield plane and parallel faces. NOTE 1—It is desirable to include details of the origin of the specimen and subsequent treatment.

Enviado por Thamyres flag Denunciar. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows: One operator in each laboratory tested ten specimens of each material. Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being tested, are ast in the following table: A number in parentheses indicates the year of last reapproval.

Discard any pieces exhibiting cracks or flaws visible to the unaided eye. New cushion pads shall be used for each specimen.

Current edition approved Sept. These faces shall be perpendicular. Precision and Bias 8. The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen.
