Screening and quality control of petroleum products and fuels can be a tedious and expensive process when performed with traditional methods. A faster and more efficient approach utilizing Near-Infrared Spectroscopy (NIRS) is presented in a free webinar by Metrohm in association with Digital Refining on June 16, 2021. Participants will get an overview what NIRS is, how to implement this ...
AMETEK Grabner Instruments’ ASTM D7094 flashpoint method made history in 2013, when ASTM members accepted the method for ASTM Diesel Fuel and Kerosene specifications. Recently, ASTM members expressed their confidence again in the method and voted to include the flashpoint method in ASTM D7467 Biodiesel (B6 to B20) specifications. A inter-laboratory study in 2013 using AMETEK Grabner ...
The requirements specified for diesel fuel oils shall be determined in accordance with the following test methods: flash point; cloud point; water and sediment; carbon residue; ash; distillation; viscosity; sulfur; copper corrosion; cetane number; cetane index; aromaticity; lubricity; and conductivity. ...
The aromatic hydrocarbon content of motor diesel fuel is a factor that can affect exhaust emissions and fuel combustion characteristics, as measured by cetane number. The United States Environmental Protection Agency (US EPA) regulates the aromatic content of diesel fuels. California Air Resources Board (CARB) regulations place limits on the total aromatics content and ...
This standard describes an apparatus that provides the versatility required to conduct oxidation or thermal stability tests on liquids using a wide variety of test conditions. It is sufficiently flexible so that new test conditions can be chosen in response to the changing demands of the marketplace. Procedures using this apparatus are described in the following ASTM ...
The distillation (volatility) characteristics of hydrocarbons have an important effect on their safety and performance, especially in the case of fuels and solvents. The boiling range gives information on the composition, the properties, and the behavior of the fuel during storage and use. Volatility is the major determinant of the tendency of a ...
Grabner Instruments, a subsidiary of AMETEK, Inc. has introduced a new portable and highly versatile FTIR spectrometer for the fully automatic measurement of gasoline, diesel and biofuel blends. The MINISCAN IRXpert is the first completely portable fuel analyzer that combines superior scanning range and resolution with the advantages of mid-IR and near-IR spectroscopy for highest measurement ...
Density is a fundamental physical property that can be used in conjunction with other properties to characterize both the light and heavy fractions of petroleum and petroleum products. Determination of the density or relative density of petroleum and its products is necessary for the conversion of measured volumes to volumes at ...
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 from used oil analysis and component measurements before and after test. The test method may be used for engine oil specification acceptance when all details of ...
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 and aftercooled four-cycle diesel engine with sliding tappet followers equipped with exhaust gas recirculation hardware. The design of the engine used ...
CCS apparent viscosity is not suitable for predicting low temperature flow to the engine oil pump and oil distribution system. Engine cranking data were measured by the Coordinating Research Council (CRC) L-49 test with reference oils that had viscosities between 600 and 8400 mPa•s (cP) at –17.8°C and between 2000 and 20 000 ...
Significance and Use This test method was developed to assess the performance of an engine oil to control engine wear and deposits under heavy-duty operating conditions selected to accelerate soot generation, valve train wear, and deposit formation in a turbocharged, aftercooled four-stroke-cycle diesel engine equipped ...
This test provides a guide for determining the demulsibility characteristic of lubricating oils that are prone to water contamination and may encounter the turbulence of pumping and circulation capable of producing water-in-oil emulsions. 1. Scope 1.1 This test method covers the measurement of the ability of oil and water to separate from each ...
Copper corrosion limits provide assurance that difficulties will not be experienced in deterioration of the copper and copper-alloy fittings and connections that are commonly used in many types of utilization, storage, and transportation equipment. 1. Scope 1.1 This test method covers the detection of the presence of components in liquefied petroleum ...
Like Test Methods D2550 and D3602, this test method can detect carryover traces of refinery treating residues in fuel as produced. ...
Scope 1.1 This test method is commonly referred to as the Mack T-10. This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including lead corrosion and wear of piston rings and cylinder liners. 1.2 This test method also provides ...
The fuels shall be sampled and tested appropriately to examine their conformance to detailed requirements as to composition, volatility, fluidity, combustion, corrosion, thermal stability, contaminants, and additives. ...
This test method is used to evaluate the ability of a grease to adhere to a metal surface when subjected to direct water spray. The results obtained from the use of this test method suggest correlation in operations involving direct water spray impingement such as steel mill roll neck bearing service. This test method is used for quality control and ...
Scope 1.1 This test method covers the procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. 1.2 The differential pressure values in mm Hg are defined only in terms of this test method. 1.3 The values stated in SI units are to be regarded as standard. ...
Apparent viscosity versus shear rate information can be useful in predicting pressure drops in grease distribution systems under steady-state flow conditions at constant temperature. 1. Scope 1.1 This test method covers measurement, in poises, of the apparent viscosity of lubricating greases in the temperature range from −54 to 38°C (−65 to ...
