ASTM D4810 – Standard Test Method for Hydrogen Sulfide in Natural Gas Using Length-of-Stain Detector Tubes Description: Significance and Use 5.1 The measurement of hydrogen sulfide in natural gas is important because of gas quality specifications, the corrosive nature of H2S on pipeline materials, and the effects of H2S on utilization equipment. 5.2 This test method provides …
ASTM D4809 – Standard Test Method for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter (Precision Method) Description: Significance and Use 5.1 The heat of combustion is a measure of the energy available from a fuel. A knowledge of this value is essential when considering the thermal efficiency of equipment for producing either power …
ASTM D4808 – Standard Test Methods for Hydrogen Content of Light Distillates, Middle Distillates, Gas Oils, and Residua by Low-Resolution Nuclear Magnetic Resonance Spectroscopy Description: Significance and Use 5.1 The hydrogen content represents a fundamental quality of a petroleum product that has been correlated with many of the performance characteristics of that product. 5.2 This test method …
ASTM D4807 – Standard Test Method for Sediment in Crude Oil by Membrane Filtration Description: Significance and Use 4.1 A knowledge of the sediment content of crude oil is important both in refinery operations and in crude oil commerce. Scope 1.1 This test method covers the determination of sediment in crude oils by membrane filtration. This test …
ASTM D4806 – Standard Specification for Denatured Fuel Ethanol Description: Abstract This specification covers nominally anhydrous denatured fuel ethanol intended for blending with unleaded or leaded gasolines for use as a spark-ignition automotive engine fuel. Denatured fuel ethanol shall conform to the specified performance requirements for the following: ethanol content, methanol, solvent-washed gum, water content, …
ASTM D4804 – Standard Test Method for Determining the Flammability Characteristics of Nonrigid Solid Plastics Description: Significance and Use 5.1 The test results represent the afterflame and afterglow times, in seconds, for a material under the conditions of the test. 5.2 The afterflame and afterglow times and other burning phenomena will vary with thickness. Test data shall …
ASTM D4803 – Standard Test Method for Predicting Heat Buildup in PVC Building Products Description: Significance and Use 5.1 Heat buildup in PVC exterior building products due to absorption of the energy from the sun may lead to distortion problems. Heat buildup is affected by the color, emittance, absorptance, and reflectance of a product. Generally, the …
ASTM D4799 – Standard Practice for Accelerated Weathering Test Conditions and Procedures for Bituminous Materials (Fluorescent UV, Water Spray, and Condensation Method) Description: Significance and Use 4.1 This weathering apparatus is used for comparing the weathering characteristics of bituminous materials against a control material for which the outdoor weathering characteristics are known. It is not possible …
ASTM D4798 – Standard Practice for Accelerated Weathering Test Conditions and Procedures for Bituminous Materials (Xenon-Arc Method) Description: Significance and Use 4.1 Tests conducted according to this practice are used to compare the weathering characteristics of bituminous materials versus a control material of known outdoor durability. It is not possible to establish a single relationship that …
ASTM D4797- Standard Test Methods for Gravimetric Analysis of White and Yellow Thermoplastic Pavement Marking Description: Significance and Use 5.1 The function of these test methods is to define the percent of binder and retroreflective optics or non-retroreflective particles in the composition of the thermoplastic pavement marking as defined by the applicable specification for the manufacture …
