1、Designation: C 1160 97 (Reapproved 2003)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 (e) 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, bak
3、ed 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 n
4、ormally used with carbon filledchemical-resistant mortars.1.2 This standard does not purport 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 reg

Significance and Use4.1 The chemical-resistant carbon brick meeting this speci-fication is intended for use in acid and alkaline service atvarying
7、temperatures. Physical stress imposed on the brickattributable to thermal shock or pressure 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.4.2
8、 The performance of the brick as tested in Test MethodsC 1106 or other tests, or other qualifying data, should bereviewed between the purchaser and the seller.5. Sampling5.1 The brick shall be sampled in accordance with TestMethods C 67.6. Chemical Resistance6.1 Carbon brick are inherently non-wetti
9、ng and highlyresistant to many acids, alkalies, salts, and solvents andcombinations of these chemicals at varying temperatures andconcentrations.6.2 The carbon brick shall be tested in accordance with TestMethods C 1106 using a chemical and thermal environment.1This specification is under the jurisd
