5、d (Note 1):3.1.1 Type TFor use where a high degree of resistance tothermal and mechanical shock is required but low absorption isnot required.3.1.2 Type HFor use where resistance to chemicals andthermal shock are service factors but low absorption is notrequired.3.1.3 Type MFor use where low absorpt
6、ion is required.Brick of this type are normally characterized by limitedmechanical (impact) shock resistance but are often highlyresistant to abrasion.3.1.4 Type LFor use where minimal absorption and a highdegree of chemical resistance are required. Brick of this typeare normally characterized by ve
7、ry limited thermal and limitedmechanical (impact) shock resistance but are highly resistant toabrasion.NOTE 1Discussion of Types of Floor BrickThe four types of brickincluded in this specification are designed to cover the diverse needs ofmany industries for floor units. Recognizing that the require
8、ments ofprimary aluminum producers are quite different from those of chemicalmanufacturers, and similarly, that the need of a builder for brick withwhich to pave an airport terminal building may vary considerably fromthose of food processing plants, for example, a minimum of four bricktypes has been
9、 deemed necessary. The factors of modulus of rupture,water absorption, and chemical resistance have been selected as the basisfor the classification system.4. Physical Properties4.1 Brick shall conform to the physical requirements for thetype specified as prescribed in Table 1.5. Dimensions and Perm
10、issible Variations5.1 The sizes of brick shall be as specified by the purchaser.The maximum permissible variations in dimensions of indi-vidual units shall not exceed those given in Table 2.5.2 Tolerances for warpage of face or edges of individualbrick from a plane surface and from a straight line,
11、respec-tively, shall not exceed the maximum values specified in Table3.6. Finish and Appearance6.1 The texture of the finished surface that will be exposedwhen in place shall conform to an approved sample consistingof not less than four bricks, each representing the texturedesired.7. Sampling and Te
12、sting7.1 The brick shall be sampled and tested for modulus ofrupture, absorption, measurement of size, and measurement ofwarpage in accordance with Test Methods C67 and for chemi-cal resistance in accordance with the sulfuric acid solubilitytest in Section 7 on a sulfuric acid solubility test in Spe
