Last previous edition C — 88 The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows: Axtm an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator. These faces shall be perpendicular.

Single-operator component Between-laboratory component 1. 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 7c73 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 Current edition approved Sept. 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. Ideally, ceramics should be stressed this way in use.
Discard any pieces exhibiting cracks or flaws visible to the unaided aetm. A number in parentheses indicates the year of last reapproval.
NOTE 1—It is desirable to include details of the origin of the specimen and subsequent treatment. Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being tested, are shown in the following table: 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 specimen, in. If the contact block is cracked during testing, it shall be replaced.
Precision and Bias 8. Enviado por Thamyres flag Denunciar. Significance and Use 3. The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen. They may be formed and matured for the purpose of compression testing, or they may ast, cut from matured whitew- are by sawing or coredrilling.
New cushion pads shall be used for each specimen.

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