1、Designation: C 1160 97 (Reapproved 2008)Standard Specification forChemical-Resistant Carbon Brick1This standard is issued under the fixed designation C 1160; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers machine made solid uncoredcarbon brick produced from either metallurgical or petroleumcalcined coke, bake
3、d to a minimum 1850F (1010C), andsuitable for use in masonry construction which will be exposedto various chemicals. These units are designed primarily forindustries using hydrofluoric acid, fluoride salts, and highconcentrations of alkalies such as sodium and potassiumhydroxide. Carbon brick are no
4、rmally used with carbon filledchemical-resistant mortars.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not p
5、urport to address the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.

7、ons of terms used in this speci-fication, see Terminology C 904.4. Significance and Use4.1 The chemical-resistant carbon brick meeting this speci-fication is intended for use in acid and alkaline service atvarying temperatures. Physical stress imposed on the brickattributable to thermal shock or pre
8、ssure differential may ormay not be a consideration. The corrosion resistance andstructural integrity of the brick are dependent on the type andpurity of the carbon and binder used when the brick ismanufactured.1This specification is under the jurisdiction of ASTM Committee C03 onChemical-Resistant
