|Publication Date:||28 September 1984|
|ICS Code (Binders. Sealing materials):||91.100.50|
1.1 This test method covers the determination of the coking value of tar and pitch having an ash content not over 0.5 % as determined by Test Method D 2415.
1.2 Coking values by this method are practically the same as those obtained by Test Method D 189, but results are more reproducible. The apparatus used is identical, except that an electric furnace is substituted for the gas flame.
1.3 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.
