1、Designation: C1405 15C1405 16Standard Specification forGlazed Brick (Single Fired, Brick Units)1This standard is issued under the fixed designation C1405; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、 number in parentheses indicates 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, having a ceramic glaze finish fused to the body during the same process as the unit bodyfiring, that
3、 are intended for use in masonry and supplying structural or facing components, or both, to the structure. Thisspecification does not cover double-fired glazed brick. Some double-fired decorative glazes have physical properties, which varyfrom those of single-fired glazes due to the lower temperatur
4、es used in applying the decorative coating.1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of brickextracted from masonry structures for determining conformance or nonconformance to the property requirements of thisspecification is b
5、eyond the scope of this specification.1.3 Glazed brick are prismatic units available in a variety of sizes, textures, colors, and shapes. Glazed brick are manufacturedfrom clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing
6、).The heat treatment shall develop a fired bond between the particulate constituents to provide the strength and durabilityrequirements of this specification (see Terminology C1232).1.4 Glazed brick are shaped during manufacture by molding, pressing, or extrusion, and the shaping method is a way to
7、describethe brick.1.5 Glazed brick are classified into one of two grades, one of two types, one of two classes, and one of three divisions.1.6 Opacity of the glaze is not required unless specified by the purchaser.1.7 The text of this standard references notes and footnotes that provide explanatory
8、material. These notes and footnotes(excluding those in tables and figures) shall not be considered as requirements of this standard.1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for
9、information only and are not considered standard.1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of reg

17、n of Building Material53. Terminology3.1 DefinitionsTerms used in this specification are defined in accordance with Terminology C1232.4. Classification4.1 GradesGrades classify glazed brick according to their permissible variation in face dimension as follows. When grade isnot specified, the require
18、ments for Grade S govern.4.1.1 Grade S (Standard), units for use where standard dimensional tolerances are desired.4.1.2 Grade SS (Select Sized), units for use where a higher degree of precision and lower permissible variation in size aredesired.4.2 TypesTwo types of glazed brick are covered. When t
19、ype is not specified, the requirements for Type I govern.4.2.1 Type I (Single-Faced Units), for general use where only one face is finished.4.2.2 Type II (Two-Faced Units), for use where two opposite faces are finished.4.3 ClassesTwo classes of glazed brick are covered. When class is not specified,
20、the requirements for Class Exterior govern.4.3.1 Class Exterior, for exterior applications.4.3.2 Class Interior, for interior applications.4.4 DivisionsThree divisions of glazed brick are covered. Divisions identify the amount and placement of hollow spaces(cores, cells and deep frogs) in the cross
21、section of the unit. In the Division nomenclature, H shall be understood to mean hollow,and V shall be understood to mean void.4.4.1 Division SolidBrick with void area less than or equal to 25 % of its gross cross sectional area, measured in any planeparallel to the surface containing the cores, cel
22、ls, or deep frogs.4.4.2 Division H40VBrick with void area greater than 25 % but less than or equal to 40 % of its gross cross sectional area,measured in any plane parallel to the surface containing the cores, cells, or deep frogs.4.4.3 Division H60VBrick with void area greater than 40 % but less tha
23、n or equal to 60 % of its gross cross sectional area,measured in any plane parallel to the surface containing the cores, cells, or deep frogs. The shell thicknesses shall comply withthe requirements in Table 1. See Fig. 1.5. Physical Properties5.1 DurabilityGlazed brick shall conform to the physical
24、 properties requirements for the class specified as prescribed in Table2 or in 5.1.1 or 5.1.2. For the compressive strength requirements, test the unit with the compressive force perpendicular to the bedsurface of the unit, with the unit in the stretcher position.NOTE 1The physical property requirem
