Standard Test Method for Determination of the Viable Aerobic Microbial Content of Fuels and Associated Water—Thixotropic Gel Culture Method
Abstract: 5.1 This test method is intended to provide a tool for assessing whether fuel storage and distribution facilities or end user fuel tanks are subject to microbial growth and alert fuel suppliers or users to the potential ... -
Standard Test Method for Determination of Light Hydrocarbons and Cut Point Intervals in Live Crude Oils and Condensates by Gas Chromatography
Abstract: 5.1 This test method determines methane (nC1) to hexane (nC6), cut point carbon fraction intervals to nC24 and recovery (nC24+) of live crude oils and condensates without depressurizing, thereby avoiding the loss of highly ... -
Standard Test Method for Modified Fouling Index (MFI-0.45) of Water
Abstract: 5.1 This test method is an alternative for the silt density index (SDI) method (Test Method D4189) with the aim to overcome inaccuracies related to a nonlinear relation with the fouling potential due to particulate matter ... -
Standard Test Method for Chloride Content Determination of Aviation Turbine Fuels using Chloride Test Strip
Abstract: 5.1 Chloride present in aviation turbine fuel can originate from refinery salt drier carryover or possibly from seawater contamination (for example, product transferred by barge). Elevated chloride levels have caused ... -
Standard Specification for Disproportionation (TDP) Toluene
Abstract: This specification establishes requirements for disproportionation (TDP) toluene. For purposes of determining conformance with this specification, an observed value or a calculated value shall be rounded off "to the nearest ... -
Standard Test Method for Shear Testing of Powders Using the Freeman Technology FT4 Powder Rheometer Shear Cell
Abstract: 5.1 The test can be used to evaluate the following: 5.1.1 Classification or Comparison of Powders—There are several parameters that can be used to classify powders relative to each other, the most useful being the measured ... -
Standard Test Method for Measuring the Merit of Dispersancy of In-Service Engine Oils with Blotter Spot Method
Abstract: 5.1 Dispersancy is the property that allows oil to suspend and carry away pollutants of diverse sources such as soot from combustion, metallic particles from wear, corrosion of mechanical parts, and insoluble products ... -
Standard Test Method for Moisture in Cotton by Oven-Drying
Abstract: 5.1 This test method for testing the moisture content of cotton can be used for acceptance testing of commercial shipments of lint cotton provided the between-laboratory bias is known. 5.1.1 If there are differences or ... -
Standard Test Method for Determination of 4-Carboxybenzaldehyde and p-Toluic Acid in Purified Terephthalic Acid by Reverse Phase High Performance Liquid Chromatography
Abstract: 4.1 The presence of 4-CBA and p-TOL in PTA used for the production of polyester is undesirable because they can affect the PET quality (such as contribute to fiber breaks), the polymerization process, and 4-CBA imparts ... -
Standard Terminology for Radiochemical Analyses
Abstract: 3.1 This terminology standard describes terms and definitions used in standards for radiochemical analysis maintained by ASTM Committee D19 on Water. The terminology is also recommended for general use in the radiochemistry ... -
Standard Test Method for Evaluating the Flexural Properties and Internal Bond Strength of Fire-Retarded Mat-Formed Wood Structural Composite Panels Exposed to Elevated Temperatures
Abstract: 5.1 The properties evaluated by this test method are intended to provide comparative information on the effects of fire-retardant chemical formulations and environmental conditions on the flexural properties and IB strength ... -
Standard Specification for Biological Properties of Industry Reference Materials (IRM)
Abstract: This specification covers the biological quality specifications or requirements, or both, for Industry Reference Materials (IRMs) used to conduct product, specification, and development testing in the rubber and carbon ... -
Standard Classification for Nomenclature of Reference Materials of Committee D24
Abstract: 3.1 Standard reference materials are used for calibration and verification of many carbon black tests under the jurisdiction of D24. This practice defines a systematic means of naming these reference materials and does so ... -
Standard Guide for Electronic Methods for Detecting and Locating Leaks in Waterproof Membranes
Abstract: 4.1 The failure to correct membrane defects during and as soon as possible after its installation can cause premature failure of the membrane. Problems include design deficiencies, faulty application of the membrane system, ... -
Standard Test Method for Determination of Fatty Acid Methyl Esters (FAME) in Diesel Fuel by Linear Variable Filter (LVF) Array Based Mid-Infrared Spectroscopy
Abstract: 5.1 Biodiesel is a fuel commodity primarily used as a blending component with diesel fuel. It is important to check the concentration of biodiesel in the diesel fuel in order to make sure it is either not below the minimum ... -
