1、Designation: C 410 08Standard Specification forIndustrial Floor Brick1This standard is issued under the fixed designation C 410; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses ind
2、icates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers brick made from clay or shaleor mixtures thereof and are suitable for surfacing industrialfloors. Ceramic shapes known as quarry tile
3、 are not covered bythis specification. Four types of industrial floor brick arecovered (Note 1):1.1.1 Type TFor use where a high degree of resistance tothermal and mechanical shock is required but low absorption isnot required.1.1.2 Type HFor use where resistance to chemicals andthermal shock are se
4、rvice factors but low absorption is notrequired.1.1.3 Type MFor use where low absorption is required.Brick of this type are normally characterized by limitedmechanical (impact) shock resistance but are often highlyresistant to abrasion.1.1.4 Type LFor use where minimal absorption and a highdegree of
5、 chemical resistance are required. Brick of this typeare normally characterized by very 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 co
6、ver the diverse needs ofmany industries for floor units. Recognizing that the requirements 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 fr
7、omthose of food processing plants, for example, a minimum of four bricktypes has been deemed necessary. The factors of modulus of rupture,water absorption, and chemical resistance have been selected as the basisfor the classification system.1.2 The values stated in inch-pound units are to be regarde
