Scope*1.1 This specification covers brick, having a ceramic glazefinish fused to the body during the same process as the unitbody firing, that are inte
3、nded for use in masonry and supplyingstructural or facing components, or both, to the structure. Thisspecification does not cover double-fired glazed brick. Somedouble-fired decorative glazes have physical properties whichvary from those of single-fired glazes due to the lowertemperatures used in ap
4、plying the decorative coating.1.2 The property requirements of this specification apply atthe time of purchase. The use of results from testing of brickextracted from masonry structures for determining conform-ance or nonconformance to the property requirements of thisspecification is beyond the sco
5、pe of this specification.1.3 Glazed brick are prismatic units available in a variety ofsizes, textures, colors, and shapes. Glazed brick are manufac-tured from clay, shale, or similar naturally occurring earthysubstances and subjected to a heat treatment at elevatedtemperatures (firing). The heat tr
6、eatment shall develop a firedbond between the particulate constituents to provide thestrength and durability requirements of this specification (seeTerminology C1232).1.4 Glazed brick are shaped during manufacture by mold-ing, pressing, or extrusion, and the shaping method is a way todescribe the br
7、ick.1.5 Glazed brick are classified into one of two grades, one oftwo types, one of two classes, and one of three divisions.1.6 Opacity of the glaze is not required unless specified bythe purchaser.1.7 The text of this standard references notes and footnoteswhich provide explanatory material. These
8、notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of this standard.1.8 The values stated in inch-pound units are to be regardedas standard.

17、ades classify glazed brick according to theirpermissible variation in face dimension as follows. Whengrade is not specified, the requirements for Grade S govern.4.1.1 Grade S (Standard), units for use where standarddimensional tolerances are desired.4.1.2 Grade SS (Select Sized), units for use where
18、 a higherdegree of precision and lower permissible variation in size aredesired.4.2 TypesTwo types of glazed brick are covered. Whentype is not specified, the requirements for Type I govern.4.2.1 Type I (Single-Faced Units), for general use whereonly one face is finished.4.2.2 Type II (Two-Faced Uni
