ASTM D4746-98(2008) 用加压过滤法测定焦油和硬沥青中喹啉不溶物含量的试验方法

This test method is useful in evaluating and characterizing tar and pitch and as one element in establishing the uniformity of shipments and sources of supply.1.1 This test method covers the determination of the quinoline-insoluble matter (QI) in tar and pitch by pressure filtration and gives results comparable to those obtained by Test Method D 2318. 1.2 Since this test method is empirical, strict adherence to all details of the procedure is necessary. 1.3 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. 1.4 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. Specific hazards are given in Section 7, 6.2, and 6.3.

Standard Test Method for Determination of Quinoline Insolubles (QI) in Tar and Pitch by Pressure Filtration

ASTM D4072-98(2008) 测定焦油和硬沥青中甲苯不溶物质(TI)含量的标准试验方法

This test method is useful for evaluating and characterizing tars and pitches and as one element in establishing the uniformity of shipments or sources of supply.1.1 This test method covers the determination of toluene-insoluble matter (TI) in tar and pitch. 1.2 Since this test method is empirical, strict adherence to all details of the procedure is necessary. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. For specific hazard information, see Section 7.

Standard Test Method for Toluene-Insoluble (TI) Content of Tar and Pitch

ASTM D4715-98(2008)e1 测定焦油和硬沥青焦化值的试验方法(Alcan)

This test method is useful for indicating the relative coke-forming propensities and for evaluating and characterizing tars and pitches. The test method can also be used as one element in establishing the uniformity of shipments or sources of supply.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 test method are higher than those obtained by Test Method D 2416. See the bias statement in Section 13. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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.

Standard Test Method for Coking Value of Tar and Pitch (Alcan)

ASTM D4715-98(2012) 焦油和硬沥青焦化值测定的标准试验方法(Alcan)

1.1 This test method covers the determination of the coking value of tar and pitch having an ash content not over 0.58201;%, as determined by Test Method D2415. 1.2 Coking values by this test method are higher than those obtained by Test Method D2416. See the bias statement in Section 13. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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.

Standard Test Method for Coking Value of Tar and Pitch (Alcan)

ASTM D2416-84(2009) 煤焦油和硬沥青的焦化值(改进的残碳)标准试验方法

This test method is useful for indicating the relative coke-forming propensities and for evaluating and characterizing tars and pitches. This test method can also be used as one element in establishing the uniformity of shipments or sources of supply. FIG. 1 Apparatus for Determining Carbon Residue1.1 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 D2415. 1.2 Coking values by this test method are practically the same as those obtained by Test Method D189, 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.
