ASTM C216 - 17a
Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale)
饰面砖(粘土或页岩制实心砌块)的标准规范
Abstract
This specification covers brick intended for use in masonry and supplying structural or facing components, or both, to the structure. Bricks shall be classified according to their resistance to damage by freezing when saturated at a moisture content: Grade SW and Grade MW. The facing bricks shall be classified into three types: Types FBS; FBX; and FBA. Durability; absorption alternate; freezing and thawing alternative; breakage and weight loss; cracking; low weathering index alternative; compressive strength; and initial rate of absorption requirements shall be tested for the material to meet the specified requirements.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers brick intended for use in masonry and supplying structural or facing components, or both, to the structure.
1.2 The 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 requirements of this specification is beyond the intent of this specification.
1.3 The brick are prismatic units available in a variety of sizes, textures, colors, and shapes. This specification is not intended to provide specifications for paving brick (see Specification C902).
1.4 Brick are ceramic products manufactured primarily from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). Additives or recycled materials are permitted to be included at the option of the manufacturer. The heat treatment must develop a fired bond between the particulate constituents to provide the strength and durability requirements of this specification (see Terminology C1232).
1.5 Brick are shaped during manufacture by molding, pressing, or extrusion, and the shaping method is a way to describe the brick.
1.5.1 This standard 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.
1.6 Three types of brick in each of two grades are covered.
1.7 The text of this specification 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 the 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 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.
