Description

ASTM C1160-97-Reapproved2012

Withdrawn Standard: Standard Specification for Chemical-Resistant Carbon Brick (Withdrawn 2021)

ASTM C1160

Scope

1.1 This specification covers machine made solid uncored carbon brick produced from either metallurgical or petroleum calcined coke, baked to a minimum 1850°F (1010°C), and suitable for use in masonry construction which will be exposed to various chemicals. These units are designed primarily for industries using hydrofluoric acid, fluoride salts, and high concentrations of alkalies such as sodium and potassium hydroxide. Carbon brick are normally used with carbon filled chemical-resistant mortars.

TABLE 1 General Guide to Chemical Resistance of Carbon Brick

Note 1—This table is intended for use as a general guide to the resistance of carbon brick in immersion service at ambient temperatures. Specific recommendations should be obtained from the carbon brick manufacturer. Carbon brick can be used to 650°F (340°C). Over 650°F (340°C), strict environmental control is paramount to ensure that the environment is non-oxidizing.

^A R = Recommended.

TABLE 2 Physical and Chemical Requirements

1.2 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.

1.3 This standard does not purport to address 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.
