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 …
ASTM D2880 – Standard Specification for Gas Turbine Fuel Oils Description: Abstract This specification covers the selection of fuels for gas turbines, excepting gas turbines used in aircraft, for the guidance of interested parties such as turbine manufacturers and the suppliers and purchasers of fuel oils. The specification sets forth the properties of fuels at …
ASTM D2879 – Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope Description: Significance and Use 5.1 The vapor pressure of a substance as determined by isoteniscope reflects a property of the sample as received including most volatile components, but excluding dissolved fixed gases such as air. Vapor pressure, per se, …
