Standard Guide for Conducting Internal Pressure Tests on United Nations (UN) Packagings
Abstract: 4.1 Dangerous goods (hazardous materials) regulations require performance tests to be conducted on packaging designs before being authorized for use. The regulations do not include standardized procedures for conducting ... -
Standard Specification for Ethyl Tertiary-Butyl Ether (ETBE) for Blending with Aviation Spark-Ignition Engine Fuel
Abstract: This specification covers requirements for fuel grade ethyl tertiary-butyl ether (ETBE) that may be used for blending with fuels for aviation spark-ignition engines where permissible. The requirements for ETBE that may be ... -
Standard Test Method for Evaluation of Automotive Engine Oils for Valve-Train Wear Performance in Cummins ISB Medium-Duty Diesel Engine
Abstract: 5.1 This test method was developed to assess the performance of a heavy-duty engine oil in controlling engine wear under operating conditions selected to accelerate soot production and valve-train wear in a turbocharged ... -
Standard Test Method for Pyrolysis Solids Content in Pyrolysis Liquids by Filtration of Solids in Methanol
Abstract: 5.1 Pyrolysis liquid can be produced to various char concentrations. Increasing pyrolysis solids content can affect the pyrolysis liquid biofuel handling, atomization and storage stability in a negative manner. -
Standard Practice for Determining Residual Stresses in Extruded or Molded Sulfone Plastic (SP) Parts by Immersion in Various Chemical Reagents
Abstract: 5.1 Thermoplastic moldings contain residual stresses due to differential cooling rates through the thickness of the molding. Changes in residual stress have been found to occur with time after molding due to stress relaxation. ... -
Standard Practice for Manual Sampling of Liquid Fuels, Associated Materials and Fuel System Components for Microbiological Testing
Abstract: 5.1 Representative samples of fuel products and associated substances are required for the determination of microbial contamination in fuels and fuel systems in order to accurately assess the biodeterioration risk posed ... -
Standard Test Method for Adenosine Triphosphate (ATP) Content of Microorganisms in Fuel, Fuel/Water Mixtures, and Fuel Associated Water
Abstract: 5.1 This test method measures the concentration of ATP present in the sample. ATP is a constituent of all living cells including bacteria and fungi. Consequently, the presence of ATP is a reliable indicator of microbial ... -
Standard Practice for Collection of Integrated Samples for the Speciation of Biomass (Biogenic) and Fossil-Derived Carbon Dioxide Emitted from Stationary Emissions Sources
Abstract: 5.1 Greenhouse gases are reported to be a major contributor to global warming. Since “biomass CO2” emitted from combustion devices represents a net-zero carbon contribution to the atmosphere (that is, plants remove CO2 ... -
Standard Test Method for Determination of Vibrated Bulk Density of Calcined Petroleum Coke using a Semi-Automated Apparatus
Abstract: 5.1 Vibrated bulk density (VBD) is an indicator of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon applications. (Warning—Vibrated bulk density for a sample of calcined petroleum ... -
Standard Test Method for Evaluation of Diesel Engine Oils in T-12 Exhaust Gas Recirculation Diesel Engine
Abstract: 5.1 This test method was developed to evaluate the wear performance of engine oils in turbocharged and intercooled four-cycle diesel engines equipped with EGR and running on ultra-low sulfur diesel fuel. Obtain results ... -
Standard Practice for Indicating Oil in Abrasives
Abstract: 4.1 Oil in abrasives can be transferred to the surface being cleaned, thus contaminating it. This can cause film defects, affect adhesion of the coating applied over it, and the ultimate performance of the coating system. ... -
Standard Test Method for Determination of Relative Density and Absorption of Fine, Coarse, and Blended Aggregate Using Combined Vacuum Saturation and Rapid Submersion
Abstract: 4.1 Relative density (specific gravity) is the characteristic generally used for calculation of the volume occupied by the aggregate in various mixtures containing aggregate, including portland cement concrete, bituminous ... -
Standard Practice for Performance Testing of Packages for Single Parcel Delivery Systems
Abstract: 4.1 This practice provides a guide for the evaluation of shipping units in accordance with a uniform system, using established test methods at levels representative of those occurring in actual distribution. The recommended ... -
Standard Test Method for Determination of Volatile Organic Compounds Emitted from Carpet using a Specific Sorbent Tube and Thermal Desorption / Gas Chromatography
Abstract: 5.1 Manufacturers of carpet need to monitor emissions of VOCs to assess the environmental impact of their products indoors. These results are also used to demonstrate compliance with VOC emission limits for individual VOCs. ... -
Standard Test Method for Prolonged Worked Stability of Lubricating Grease in Presence of Water (Water Stability Test)
Abstract: 5.1 It is known that contamination by water can affect the shear stability of some greases in service. This test method is widely used to determine the wet shear stability of greases in service. Many grease specifications ... -
Standard Guide for Recordkeeping Microfiltration and Ultrafiltration Systems
Abstract: 4.1 Proper operation and maintenance of an MF or UF system are key factors in obtaining successful performance. This guide provides the necessary input for the evaluation of the performance of the MF/UF system, the ... -
