NOTE 1—It is desirable to include details of the origin aetm the specimen and subsequent treatment. Last previous edition C — 88 The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen. The ends of all specimens shall be ground or adtm to yield plane and parallel faces. If the contact block is cracked during testing, it shall be replaced. Precision and Bias 8.
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. Suitable materials for cushion pads, selected in accordance with the compressive strength range of the material being tested, are shown in the following table: One operator in each laboratory tested ten specimens of each material.
A number in parentheses indicates the year of last reapproval. Ideally, ceramics should be stressed this way in 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 designation indicates the year of original adoption or, in the case of revision, the year of last revision. Awtm cushion pads shall be used for each specimen.
Current edition approved Sept. The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows: 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.
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. These faces shall be perpendicular. Discard any pieces exhibiting cracks or flaws visible to the unaided eye.
This test is a measure of the potential load-bearing usefulness of a ceramic. Enviado por Thamyres flag Denunciar. C 5 compressive strength of the specimen, psi or MPa; P asttm total load on the specimen at failure, lbf or N; and A 5 calculated area of the bearing surface of the specimen, in.
