ASTM D2502 – Standard Test Method for Estimation of Mean Relative Molecular Mass of Petroleum Oils from Viscosity Measurements Description: Significance and Use 4.1 This test method provides a means of calculating the mean relative molecular mass of petroleum oils from another physical measurement. 4.2 Mean relative molecular mass is a fundamental physical constant that can be …
ASTM D2501 – Standard Test Method for Calculation of Viscosity-Gravity Constant (VGC) of Petroleum Oils Description: Significance and Use 4.1 The viscosity-gravity constant (VGC) is a useful function for the approximate characterization of the viscous fractions of petroleum.2 It is relatively insensitive to molecular weight and is related to a fluids composition as expressed in terms of …
ASTM D2500 – Standard Test Method for Cloud Point of Petroleum Products and Liquid Fuels Description: Significance and Use 5.1 For petroleum products and biodiesel fuels, cloud point of a petroleum product is an index of the lowest temperature of their utility for certain applications. Scope 1.1 This test method covers only petroleum products and biodiesel fuels …
ASTM D2492 – Standard Test Method for Forms of Sulfur in Coal (Withdrawn 2021) Description: Significance and Use 4.1 This test method provides for a separation of coal-associated sulfur into two commonly recognized forms: pyritic and sulfate. Organic sulfur is calculated by difference. Results obtained by the test method are used to serve a number of …
ASTM D2488 – Standard Practice for Description and Identification of Soils (Visual-Manual Procedures) Description: Significance and Use 5.1 The descriptive information required in this practice can be used to describe a soil to aid in the evaluation of its significant properties for engineering use. 5.2 The descriptive information required in this practice should be used to supplement …
ASTM D2487 – Standard Practice for Classification of Soils for Engineering Purposes (Unified Soil Classification System) Description: Significance and Use 5.1 This standard classifies soils from any geographic location into categories representing the results of prescribed laboratory tests to determine the particle-size characteristics, the liquid limit, and the plasticity index. 5.2 The assigning of a group name …
ASTM D2486 – Standard Test Methods for Scrub Resistance of Wall Paints Description: Significance and Use 4.1 Paints often become soiled, especially near doorways, windows, and in work and play areas. These test methods cover the determination of the relative resistance of different paints to erosion when repeatedly scrubbed during the life of the paint. 4.2 Test …
ASTM D2485 – Standard Test Methods for Evaluating Coatings For High Temperature Service Description: Significance and Use 4.1 Some coating systems are developed for use over steel that is exposed to high temperatures during service life. This method provides an accelerated means of determining the performance of these coating systems. Testing of coatings designed for interior …
ASTM D2475 – Standard Specification for Felt Description: Abstract This specification covers all standard types of felt in the form of rolls and sheets that are suitable for mechanical use. Certain special-purpose felts are also covered. Felts shall be classified according to thickness and mass, properties and general descriptions. Felt classifications shall be based on …
ASTM E1461 – Standard Test Method for Gel Time and Peak Exothermic Temperature of Reacting Thermosetting Resins (Withdrawn 2008) Description: Significance and Use Since the gel time and the peak exothermic temperature of a reacting thermosetting plastic composition vary with the volume of material mixed at one time, it is essential that the volume be …
