New cushion pads shall be used for each specimen. Current edition approved Sept. Ideally, ceramics should be stressed this way in use.

The ends of all specimens shall be ground or lapped to yield plane and parallel faces. Significance and Use 3.
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 the awtm, in. Place an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator.
The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen. 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.

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 astn the year of original adoption or, in the case of revision, the year of last revision.
A number in parentheses indicates the year of last reapproval.
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. Enviado por Thamyres flag Denunciar. If the contact block is cracked during testing, it shall be replaced. Precision and Bias 8.
Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being tested, are shown in the following table: A superscript epsilon e indicates an editorial change since the last revision or reapproval.
This test is a measure of the potential load-bearing usefulness of a ceramic. These faces shall be perpendicular. Originally published as C — 74 to replace C and C It is the responsibility of the user of this standard asstm establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.
Last previous edition C — 88 Single-operator component Between-laboratory component 1. Discard any pieces exhibiting cracks or flaws visible to the unaided eye. NOTE 1—It is desirable to include details of the origin of the specimen and subsequent treatment.
