ABSTRACT
This specification covers structural clay load-bearing facing tile and facing brick and other “solid masonry units” made from clay, shale, fire-clay, or mixtures thereof, with or without the addition of grog or other mixtures, having a finish consisting of a ceramic glaze fused to the body at above a certain temperature making them inseparable, excluding natural salt-glazed ware. The following grades and types are covered: Grade S which is for use with comparatively narrow mortar joints, Grade SS which is for use where variation of face dimension must be very small, Type I or single-faced unit which is for general use where only one finished face will be exposed, and Type II or two-faced unit which is for general use where two opposite finished faces will be exposed. The brick and tile are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength requirements specified. The masonry units are classified as solid masonry unit and hollow masonry unit. The former is a unit whose net cross-sectional area in every plane parallel to the bearing surface is 75 % or more of its gross cross-sectional area measured in the same plane and the latter is a unit whose net cross-sectional area in any plane parallel to the bearing surface is less than 75 % of its gross cross-sectional area measured in the same plane. Different tests shall be performed in order to determine the following properties: compressive strength, imperviousness, opacity, resistance to fading, resistance to autoclave crazing, flame spread, fuel contribution, smoke density, toxic fumes, hardness, and abrasion resistance.

ABSTRACT
This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane. The bricks are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements specified. Bricks that are colored by flashing or textured by sanding, where sand does not form a continuous coating, shall not be considered as surface-colored brick. Hollow bricks require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile, but permit greater void area and lesser distance from exposed edge to core hole than solid brick. Therefore, environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick. The hollow bricks can be classified into Grades SW and MW according to their degree of resistance to frost action and disintegration by weathering. According to their physical properties, the bricks can be classified into Types HBS, HBX, HBA, and HBB. In terms of size of void areas or hollow spaces, the bricks can be designated into Classes H40V and H60V. The brick shall be free of defects, deficiencies, and surface treatments, including coatings, that would interfere with the proper laying of the brick or significantly impair the strength or performance of the construction. Physical properties like compressive strength, water absorption, saturation coefficient, breakage, and cracks shall be determined.
SCOPE
1.1 This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion; intended for use in masonry supplying structural and/or facing components to the structure.

ABSTRACT
This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane. The bricks are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements specified. Bricks that are colored by flashing or textured by sanding, where sand does not form a continuous coating, shall not be considered as surface-colored brick. Hollow bricks require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile, but permit greater void area and lesser distance from exposed edge to core hole than solid brick. Therefore, environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick. The hollow bricks can be classified into Grades SW and MW according to their degree of resistance to frost action and disintegration by weathering. According to their physical properties, the bricks can be classified into Types HBS, HBX, HBA, and HBB. In terms of size of void areas or hollow spaces, the bricks can be designated into Classes H40V and H60V. The brick shall be free of defects, deficiencies, and surface treatments, including coatings, that would interfere with the proper laying of the brick or significantly impair the strength or performance of the construction.

ABSTRACT
This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane. The bricks are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements specified. Bricks that are colored by flashing or textured by sanding, where sand does not form a continuous coating, shall not be considered as surface-colored brick. Hollow bricks require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile, but permit greater void area and lesser distance from exposed edge to core hole than solid brick. Therefore, environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick. The hollow bricks can be classified into Grades SW and MW according to their degree of resistance to frost action and disintegration by weathering. According to their physical properties, the bricks can be classified into Types HBS, HBX, HBA, and HBB. In terms of size of void areas or hollow spaces, the bricks can be designated into Classes H40V and H60V. The brick shall be free of defects, deficiencies, and surface treatments, including coatings, that would interfere with the proper laying of the brick or significantly impair the strength or performance of the construction. Physical properties like compressive strength, water absorption, saturation coefficient, breakage, and cracks shall be determined.

This specification covers structural clay load-bearing facing tile and facing brick and other “solid masonry units” made from clay, shale, fire-clay, or mixtures thereof, with or without the addition of grog or other mixtures, having a finish consisting of a ceramic glaze fused to the body at above a certain temperature making them inseparable, excluding natural salt-glazed ware. The following grades and types are covered: Grade S which is for use with comparatively narrow mortar joints, Grade SS which is for use where variation of face dimension must be very small, Type I or single-faced unit which is for general use where only one finished face will be exposed, and Type II or two-faced unit which is for general use where two opposite finished faces will be exposed. The brick and tile are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength requirements specified. The masonry units are classified as solid masonry unit and hollow masonry unit. The former is a unit whose net cross-sectional area in every plane parallel to the bearing surface is 75 % or more of its gross cross-sectional area measured in the same plane and the latter is a unit whose net cross-sectional area in any plane parallel to the bearing surface is less than 75 % of its gross cross-sectional area measured in the same plane. Different tests shall be performed in order to determine the following properties: compressive strength, imperviousness, opacity, resistance to fading, resistance to autoclave crazing, flame spread, fuel contribution, smoke density, toxic fumes, hardness, and abrasion resistance.

ABSTRACT
This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane. The bricks are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements specified.

Hollow bricks require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile, but permit greater void area and lesser distance from exposed edge to core hole than solid brick. Therefore, environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick. The hollow bricks can be classified into Grades SW and MW according to their degree of resistance to frost action and disintegration by weathering. According to their physical properties, the bricks can be classified into Types HBS, HBX, HBA, and HBB.

ABSTRACT
These test methods cover procedures for the sampling and testing of brick and structural clay tile. The tests include modulus of rupture, compressive strength, absorption, saturation coefficient, effect of freezing and thawing, efflorescence, initial rate or absorption, and determination of weight, size, warpage, length chanange, and void areas. For purposes of these tests, full-size bricks, tiles, or solid masonry units shall be used as test specimens. They shall be representative of the lot of units from which they are to be selected in respect of the range of colors, textures, and sizes and shall be free of or brushed to remove dirt, mud, mortar, or other foreign materials unassociated with the manufacturing process.
SCOPE
1.1 These test methods cover procedures for the sampling and testing of brick and structural clay tile. Although not necessarily applicable to all types of units, tests include modulus of rupture, compressive strength, absorption, saturation coefficient, effect of freezing and thawing, efflorescence, initial rate of absorption and determination of weight, size, warpage, length change, and void area. (Additional methods of test pertinent to ceramic glazes include imperviousness, chemical resistance, opacity, and resistance to crazing.  
1.2 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
Note 1: The testing laboratory performing this test method should be evaluated in accordance with Practice C1093.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

ABSTRACT
This specification deals with the standards for bricks, having a ceramic glaze finish fused to the body during the same process as the unit body firing, that are intended for use in masonry. These products are also proposed for use in supplying structural or facing components. This specification, however, doest not cover double-fired glazed brick. The bricks shall be available in two grades: grade S (standard) and grade SS (select sized). Two types and classes of bricks are also covered: type I (single-faced units) and type II (two-faced units); and class exterior and class interior. The glazed bricks shall also conform to the physical properties such as durability, strength and absorption requirements and freezing and thawing requirements.
SCOPE
1.1 This specification covers brick, having a ceramic glaze finish fused to the body during the same process as the unit body firing, that are intended for use in masonry and supplying structural or facing components, or both, to the structure. This specification does not cover double-fired glazed brick. Some double-fired decorative glazes have physical properties, which vary from those of single-fired glazes due to the lower temperatures 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 brick extracted from masonry structures for determining conformance or nonconformance to the property requirements of this specification is beyond 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 manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop a fired bond between the particulate constituents to provide the strength and durability requirements 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 describe the 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 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 mathematical conversions to SI units that are provided for 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 responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane. The bricks are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements specified. Bricks that are colored by flashing or textured by sanding, where sand does not form a continuous coating, shall not be considered as surface-colored brick. Hollow bricks require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile, but permit greater void area and lesser distance from exposed edge to core hole than solid brick. Therefore, environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick. The hollow bricks can be classified into Grades SW and MW according to their degree of resistance to frost action and disintegration by weathering. According to their physical properties, the bricks can be classified into Types HBS, HBX, HBA, and HBB. In terms of size of void areas or hollow spaces, the bricks can be designated into Classes H40V and H60V. The brick shall be free of defects, deficiencies, and surface treatments, including coatings, that would interfere with the proper laying of the brick or significantly impair the strength or performance of the construction. Physical properties like compressive strength, water absorption, saturation coefficient, breakage, and cracks shall be determined.
SCOPE
1.1 This specification covers hollow building brick and hollow facing brick made from clay, shale, fire clay, or mixtures thereof, and fired to incipient fusion. Four types of hollow brick in each of two grades and two classes are covered. In this specification, the term hollow brick shall be understood to mean hollow clay masonry units whose net cross-sectional area (solid area) in any plane parallel to the surface, containing the cores, cells, or deep frogs, is less than 75 % of its gross cross-sectional area measured in the same plane (see 4.3). This specification does not cover brick intended for use as paving brick (see Specification C902).  
1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or nonconformance to the property requirements (Section 6) of this standard is beyond the scope of this specification.  
1.3 Brick covered by this specification are ceramic products manufactured primarily from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment shall develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification. Additives or recycled materials are permitted to be included at the option of the manufacturer. (See “firing” and “firing bond” in Terminology C1232.)  
1.3.1 This specification and its individual requirements shall not be used to qualify or corroborate the performance of a masonry unit made from other materials, or made with other forming methods, or other means of binding the materials.  
1.4 Hollow brick differ from unglazed structural clay tile (Specifications C34 and C212) and solid brick (Specifications C62 and C216). Hollow brick require greater shell and web thicknesses and higher minimum compressive s...

ABSTRACT
This specification covers structural clay load-bearing facing tile and facing brick and other “solid masonry units” made from clay, shale, fire-clay, or mixtures thereof, with or without the addition of grog or other mixtures, having a finish consisting of a ceramic glaze fused to the body at above a certain temperature making them inseparable, excluding natural salt-glazed ware. The following grades and types are covered: Grade S which is for use with comparatively narrow mortar joints, Grade SS which is for use where variation of face dimension must be very small, Type I or single-faced unit which is for general use where only one finished face will be exposed, and Type II or two-faced unit which is for general use where two opposite finished faces will be exposed. The brick and tile are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength requirements specified. The masonry units are classified as solid masonry unit and hollow masonry unit. The former is a unit whose net cross-sectional area in every plane parallel to the bearing surface is 75 % or more of its gross cross-sectional area measured in the same plane and the latter is a unit whose net cross-sectional area in any plane parallel to the bearing surface is less than 75 % of its gross cross-sectional area measured in the same plane. Different tests shall be performed in order to determine the following properties: compressive strength, imperviousness, opacity, resistance to fading, resistance to autoclave crazing, flame spread, fuel contribution, smoke density, toxic fumes, hardness, and abrasion resistance.

1.2 The property requirements of this standard apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or non-conformance to the property requirements (Section 5) of this standard is beyond the scope of this standard.  
1.3 Brick covered by this standard are manufactured from clay, shale, or similar naturally occurring substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirements of this specification. (See firing and fired bond  in Terminology C1232.)  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
