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 …
ASTM D2902 – Standard Specification for Fluoropolymer Resin Heat-Shrinkable Tubing for Electrical Insulation Description: AbstractThis specification applies to flexible fluoropolymer resin heat-shrinkable extruded tubing made from tetrafluoroethylene resin, copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), and from perfluoroalkoxy (PFA) resin for use as electrical insulation. This specification covers three types of tubings, namely: Type I tubing, …
ASTM D2896 – Standard Test Method for Base Number of Petroleum Products by Potentiometric Perchloric Acid Titration Description: Significance and Use 5.1 New and used petroleum products can contain basic constituents that are present as additives. The relative amounts of these materials can be determined by titration with acids. The base number is a measure of …
ASTM D2893 – Standard Test Methods for Oxidation Characteristics of Extreme-Pressure Lubrication Oils Description: Significance and Use 4.1 These test methods have been widely used to measure the oxidation stability of extreme pressure lubricating fluids, gear oils, and mineral oils. Scope 1.1 These test methods (A and B) cover the determination of the oxidation characteristics of extreme-pressure …
ASTM D2892 – Standard Test Method for Distillation of Crude Petroleum (15-Theoretical Plate Column) Description: Significance and Use 5.1 This test method is one of a number of tests conducted on a crude oil to determine its value. It provides an estimate of the yields of fractions of various boiling ranges and is therefore valuable in …
ASTM D2890 – Standard Test Method for Calculation of Liquid Heat Capacity of Petroleum Distillate Fuels Description: Significance and Use 5.1 Heat capacities obtained by this method are those at atmospheric pressure. However, because the temperature range is low, the calculated values are similar to saturated liquid heat capacities in the temperature-pressure range required for most …
ASTM D2889 – Standard Test Method for Calculation of True Vapor Pressures of Petroleum Distillate Fuels Description: Significance and Use 5.1 The true vapor pressure of a distillate fuel is a relative measurement, both of the tendency of the most volatile portion of the fuel to gasify, and of the restraining pressure required to prevent gasification …
