One operator in each laboratory tested ten specimens of each material. Suitable materials for f773 pads, selected in accordance with the compressive strength range of the material being tested, are shown in the following table: It is the responsibility qstm the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. If the contact block is cracked during testing, it shall be replaced.

Single-operator component Between-laboratory component 1. 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.
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. Discard any pieces exhibiting cracks or flaws visible to the unaided eye. Last previous edition C — 88 These faces shall be perpendicular. NOTE 1—It is desirable to include details of the origin of the specimen and subsequent treatment.

Place an appropriate guard around the specimen to contain flying fragments at failure; eye protection should be used by the operator. Significance and Use 3. Precision and Bias 8.
The compo- nents of variance for compressive strength results expressed as coefficients of variation were calculated as follows: The spherical surfaces shall be well lubricated, and the center of curvature shall lie on the lower face of the platen.
C — 88 Reapproved Standard Test Method for Compressive Crushing Strength of Fired Whiteware Materials1 This standard is issued under the fixed designation C ; c73 number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
New cushion pads shall zstm used for each specimen.
The ends of all specimens shall be ground or lapped to yield plane and parallel faces. This test is a measure of the aastm load-bearing usefulness of a ceramic. Ideally, ceramics should be stressed this way in use.
