ASTM C980-88(1995)e1

Standard Specification for Industrial Chimney Lining Brick

SCOPE
1.1 This specification covers solid kiln fired brick made from clay, shale, or mixtures thereof suitable for use in masonry construction in contact with the chemicals present in flue gases found in industrial chimneys. These brick are normally used with chemical-resistant mortars.  
1.2 The physical and chemical properties of chimney lining brick differ from supplier to supplier mainly because their composition is determined by the source of raw materials. Chimney lining brick, regardless of these differences, are considered to be of three types noted as follows:  
1.2.1 Type I-- For use where low absorption and high acid resistance are not major factors.  
1.2.2 Type II-- For use where lower absorption and higher acid resistance are required.  
1.2.3 Type III-- For use where lowest absorption and highest acid resistance are required.  
Note 1--Types I, II, and III may not differ significantly in their resistance to thermal shock, and selection of brick type should be based upon their absorption and acid-resistant service requirements.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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.
