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 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 ) of this specification is beyond the scope 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 C 902).1.4 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 must develop a fired bond between the particulate constituents to provide the strength and durability requirements of this specification (see firing, fired bond, and incipient fusion in Terminology C 43).1.5 Brick are shaped during manufacture by molding, pressing, or extrusion, and the shaping method is a way to describe the brick. 1.6 Three types of brick in each of two grades are covered.1.7 The text of this specification 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.1.8 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

This specification is not intended to provide specifications for paving brick (see Specification C902). 1.4x00a0;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). 1.5x00a0;Brick are shaped during manufacture by molding, pressing, or extrusion, and the shaping method is a way to describe the brick. 1.5.1x00a0;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. 1.6x00a0;Three types of brick in each of two grades are covered. 1.7x00a0;The text of this specification 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. 1.8x00a0;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.
1.1x00a0;This specification covers fly ash brick intended for use in masonry, which are made from fly ash, water, and suitable mineral aggregates with or without the inclusion of other materials, and without the use of portland cement. This specification covers units intended for use in masonry, in both structural and facing applications. 1.2x00a0;Units covered under this specification include a fly ash binder that undergoes hydraulic, pozzolanic, alkali-activated, or geopolymer reactions, or any combination thereof. These chemical reactions, in conjunction with the other materials in the units, provide the strength and durability necessary to meet the requirements of this specification. Note 1:x00a0;This specification addresses properties of units formed using fly ash, aggregates, and other allowed binders. Although not required by this standard, users may request tests that establish assembly performance such as unit-mortar bond and fire resistance. As an alternative to tests, evidence of successful use in similar applications could be provided to establish assembly performance. 1.3x00a0;This specification 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. 1.4x00a0;The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5x00a0;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 and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard describes the method of specifying the design, installation criteria for system chimneys, construction of custom built chimneys, and the relining of existing chimneys. It also gives information on commissioning of chimneys.This European Standard also deals with connecting flue pipes.This European Standard does not apply to freestanding chimneys covered by EN 13084-1.This European Standard excludes chimneys designated H (high positive pressure chimneys) and chimneys for room-sealed heating appliances. For the purpose of this European Standard the term \"installation\" includes construction.
