5.1 The volatile matter of petroleum coke affects the density of coke particles and can affect artifacts produced from further processing of the coke.5.2 The volatile matter can be used in estimating the calorific value of coke.1.1 This test method covers the determination of the volatile matter produced by pyrolysis or evolved when petroleum coke is subjected to the specific conditions of the test method.1.2 The interlaboratory study for precision covered materials with a volatile matter concentration ranging from about 8 % to 16 %.1.3 Samples having a thermal history above 600 °C are excluded.1.4 This test method is empirical and requires the entire test procedure to be closely followed to ensure that results from different laboratories will be comparable.1.5 This test method is not satisfactory for determining de-dusting material content.1.6 The values stated in SI units are to be regarded as standard.1.6.1 Exception—Non-SI units are shown in parentheses for information only.1.7 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 to establish appropriate safety, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The test method is useful for determining the water-soluble materials in vegetable-tanned leathers.4.2 The water-soluble matter includes the soluble nontanning components of the tanning materials used, sugars and materials of a similar nature, and inorganic compounds such as Epsom salts, Glauber's salts, borax, and other soluble salts added during curing and tannery processing.1.1 This test method covers the determination of the water-soluble materials in all types of vegetable-tanned leathers. This test method does not apply to wet blue.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This sampling procedure is used to collect a particulate filter sample containing particulates 0.2 µm or larger in size to be used to measure the size and concentration of particulates in a gaseous fuel stream.1.1 This practice is primarily for sampling particulates in gaseous fuels up to a nominal working pressure (NWP) of 70 MPa (10 152 psi) using an in-stream filter. This practice describes sampling apparatus design, operating procedures, and quality control procedures required to obtain the stated levels of precision and accuracy.1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 The quantity of non-dispersible matter of carbon black is important in some molded or extruded products as it may relate to the surface appearance of those products. The maximum amount of non dispersible matter and the minimum size of the particles to be analyzed in each application is normally determined and agreed to between the user and the producer.1.1 This test method covers the determination of non-dispersible matter after mechanical water flushing of regular untreated carbon blacks. It may not be applicable to oil-treated carbon blacks because the oil would prevent proper wetting of the black by water.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

AbstractThese test methods establish the standard procedures for determining the hygroscopic moisture (and other matter volatile under the test conditions) in pigments. Method A shall be performed on pigments that do not decompose at a specified temperature. This method shall require the use of a wide-mouth cylindrical glass weighing bottle, an oven, and an analytical balance. Method B, on the other hand, shall be used for pigments that decompose at the same specified temperature. This method shall also need a wide-mouth cylindrical glass weighing bottle, an open-tube manometer, a glass desiccator, an oil vacuum pump, and an analytical balance.1.1 These test methods cover procedures for determining hygroscopic moisture (and other matter volatile under the test conditions) in pigments.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
