They shall be free of observable cracks orshattered edges and shall not have laminations and fissuresmore than is typical of the

47、tile from which they are taken.12.1.2 Test specimens shall consist of segments taken fromeach of the tile broken in the crushing strength test, and theyshall be selected in accordance with the following provisions:12.1.3 For tile with nominal inside diameters of 12 in. (305mm) or less, and nominal l
