ASTM C1405-20

Standard Specification for Glazed Brick (Single Fired, Brick Units)

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.
