1.1 This test method covers methods to evaluate a charac-teristic of raw rubber or unvulcanized rubber compounds that is designated as green strength. This special strength property for uncured rubbers is an important processing performance attribute in rubber product manufacturing. 1.2 The values stated in SI units are to be regarded as standard. No other […]

1.1 This test method covers the determination of copper in jet fuels in the range of 5 µg ⁄kg to 100 µg ⁄kg using graphite furnace atomic absorption spectrometry. Copper contents above 100 µg ⁄kg may be determined by sample dilution with kerosine to bring the copper level into the aforementioned method range. When sample

1.1 This test method covers a procedure for determining the degree of biodegradability of lubricants or their components in an aerobic aqueous medium on exposure to an inoculum under controlled laboratory conditions. This test method is an ulti-mate biodegradation test that measures oxygen demand in a closed respirometer. 1.2 This test method is suitable for

1.1 This method is used to measure the adhesion strength (180 degree peel) between plies of reinforced geomembranes such as internally-reinforced geomembranes and coated fab-rics. 1.2 This method is not intended for determining the strength of geomembrane seams or for determining the ply adhesion strength of geocomposite components (such as nonwoven geotextile bonded to geomembrane,

1.1 This specification covers graded Trinidad Lake modified asphalt binders. Grading designations are related to the average seven-day maximum pavement design temperature, °C, the intermediate pavement design temperature, °C, and minimum pavement design temperature, °C. NOTE 1—For asphalt cements graded by penetration at 25 °C, see Specification D 946. For asphalt cements graded by viscosity

1.1 This practice covers determination of the color stability of a hydrocarbon resin by exposure to a specific temperature for a defined time period in a forced-draft oven. 1.2 Color stability is measured by the change in color of the test resin, measured via the yellowness index color scale, in accordance with Practice E313, or

1.1 This practice covers determination of glass transition temperatures of hydrocarbon (HC) resins by differential scan-ning calorimetry (DSC). 1.2 This practice is applicable to HC resins as defined in Terminology D6640. The normal operating temperature range is from the cryogenic region to approximately 180°C. The temperature range can be extended.

1.1 This practice covers testing to evaluate chemical constituents, chemical and physical properties of compounding materials, and compounded and cured rubbers, which may frequently be conducted by one or more test methods. When more than one test method is available, two questions arise:Which test method has the better (or best) response to or discrimination for

1.1 This practice covers the steps necessary to determine if a site is ready for closure with emphasis on general sampling techniques and how to determine if the agreed upon level of remediation has been achieved. 1.2 A minimum of statistical procedures is used in this practice.

1.1 This practice covers a test method for the evaluation of granular activated carbon (GAC) for the adsorption of soluble pollutants from water. This practice can be used to estimate the operating capacities of virgin and reactivated granular acti-vated carbons. The results obtained from the small-scale column testing can be used to predict the adsorption
