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.

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.
