ASTM C607-88(2000)

Standard Practice for Coking Large Shapes of Carbon-Bearing Materials

SCOPE
1.1 This practice covers the preparation of coking of carbon-bearing material for subsequent testing such as modulus of rupture, slag testing, thermal conductivity, and thermal expansion. Test Methods C831 is the specified method for testing residual carbon.
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.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given parentheses are provided for information only.
