ASTM D297 – Standard Test Methods for Rubber Products—Chemical Analysis Description: Abstract These test methods cover the qualitative and quantitative analyses of the composition of natural and synthetic crude rubbers. These methods are divided into general and specific test methods. General test methods shall be performed to determine the amount and type of some or …
ASTM D2961 – Standard Practice for Single-Stage Total Moisture Less than 15 % in Coal Reduced to 2.36 mm [No. 8 Sieve] Topsize Description: Significance and Use 5.1 The measurement of total moisture is required to determine whether coal meets commercial or environmental specifications, or both. Within the limitations prescribed in the scope, this practice describes a …
ASTM D2950 – Standard Test Method for Density of Asphalt Mixtures in Place by Nuclear Methods Description: Significance and Use 4.1 The test method described is useful as a rapid, nondestructive technique for determining the in-place density of compacted asphalt mixtures. 4.2 With proper calibration and confirmation testing, the test method is suitable for quality control and …
ASTM D2942 – Standard Test Method for Total Acid Acceptance of Halogenated Organic Solvents (Nonreflux Methods) Description: Significance and Use 4.1 Solvents that have been depleted in stabilizer content can become acidic. Acids can cause corrosion to process and storage equipment used for halogenated solvents. 4.2 Halogenated organic solvents may contain amine type (alkaline, aqueous extractable) acid …
ASTM D2941 – Standard Test Method for Measuring Break Pattern of Leather (Break Scale) Description: Significance and Use 4.1 Break depends on the fiber structure and on the relation between the grain and other strata of the leather. A fine break, or a grain pattern which shows many fine wrinkles when it is bent to form …
ASTM D2939 – Standard Test Methods for Emulsified Bitumens Used as Protective Coatings (Withdrawn 2012) Description: Significance and Use These tests are useful in evaluating and characterizing coal tar emulsion and other bituminous emulsions to establish uniformity of shipments. Scope 1.1 These test methods cover procedures for sampling and testing emulsified bitumens used in relatively …
ASTM D2936 – Standard Test Method for Direct Tensile Strength of Intact Rock Core Specimens Description: Significance and Use 5.1 Rock is much weaker in tension than in compression. Thus, in determining the failure condition for a rock structure, many investigators employ the tensile strength of the component rock as the failure strength for the structure. …
ASTM D293 – Standard Test Method for the Sieve Analysis of Coke Description: Significance and Use 3.1 This test method determines the size distribution of coke for conformance to specifications of percentages retained on designated screen sizes. Scope 1.1 This test method describes the separation of a coke sample into defined size fractions and expressing said fractions …
ASTM D2919 – Standard Test Method for Determining Durability of Adhesive Joints Stressed in Shear by Tension Loading Description: Significance and Use 4.1 The combination of stress and moisture decreases the durability of most adhesive joints. Stresses in the presence of water or water vapor may cause some adhesive joints to fail at some small fraction …
ASTM D2908 – Standard Practice for Measuring Volatile Organic Matter in Water by Aqueous-Injection Gas Chromatography Description: Significance and Use 5.1 This practice is useful in identifying the major organic constituents in wastewater for support of effective in-plant or pollution control programs. Currently, the most practical means for tentatively identifying and measuring a range of volatile …
