ISO 20846-2019 石油产品--汽车燃料硫含量的测定--紫外荧光法 Petroleum products -- Determination of sulfur content of automotive fuels -- Ultraviolet fluorescence method
This document specifies an ultraviolet (UV) fluorescence test method for the determination of the <br />sulfur content of the following products:<br />— having sulfur contents in the range 3 mg/kg to 500 mg/kg,<br />— motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up <br />to about 10 % (V/V)],<br />— diesel fuels, including those containing up to about 30 % (V/V) fatty acid methyl ester (FAME),<br />— having sulfur contents in the range of 3 mg/kg to 45 mg/kg,<br />— synthetic fuels, such as hydrotreated vegetable oil (HVO) and gas to liquid (GTL).<br />Other products can be analysed and other sulfur contents can be determined according to this test <br />method, however, no precision data for products other than automotive fuels and for results outside <br />the specified range have been established for this document. Halogens interfere with this detection <br />technique at concentrations above approximately 3 500 mg/kg.<br />NOTE 1 Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts <br />of sulfur-bearing materials are contained in the feedstocks.<br />NOTE 2 This test method can be used to determine sulfur in process feeds and can also be used to control <br />sulfur in effluents.<br />NOTE 3 For the purposes of this document, “% (m/m)” and “% (V/V)” are used to represent the mass fraction, <br />w, and the volume fraction, φ, of a material respectively.<br />NOTE 4 Sulfate species in ethanol do not have the same conversion factor of organic sulfur in ethanol. <br />Nevertheless, sulfates have a conversion factor close to that of organic sulfur.<br />NOTE 5 Nitrogen interference can occur, see 6.5 for further guidance....

ISO 6249-2021 石油产品--燃气轮机燃料热氧化稳定性的测定 Petroleum products — Determination of thermal oxidation stability of gas turbine fuels
This document specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. It is applicable to middle distillate and wide-cut fuels and is particularly specified for the performance of aviation gas turbine fuels.<br />The test results are indicative of fuel thermal oxidation stability during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface at a specified temperature....

NB/SH/T 6006-2020 石油产品铜腐蚀性快速试验 一次性铜箔片 Standard test method for rapid determination of corrosiveness to copper from
本标准规定了用一次性铜箔片快速评价石油产品铜腐蚀性的试验方法。<br />本标准适用于测定航空汽油、喷气燃料、车用汽油、稳定轻烃或在37.8℃时蒸气压不大于124kPa的其他烃类、溶剂油、煤油、柴油、馏分燃料油、润滑油和其他石油产品对铜的腐蚀程度。<br />警示：有些产品，如稳定轻烃，其蒸气压比车用汽油或航空汽油的典型蒸气压高，因此应特别注意，不要把装有高蒸气压的稳定轻烃或其他产品的压力容器放到100℃浴中。蒸气压超过124kPa的试样在100℃时<br />能产生很大的压力，会使压力容器破裂；故对蒸气压超过124kPa的试样，应采用SH/T0232测定。...

ISO/TR 19441-2018 石油产品--当前燃料、生物燃料和生物燃料组件的密度和温度关系 Petroleum products — Density versus temperature relationships of current fuels, biofuels and biofuel components
This document lists and describes recent density measurements at different temperatures for biofuel components and biofuel blends such as gasoline E5, E10, E85 and biodiesel B100, B7, as well as domestic heating oils and paraffinic diesel fuels.<br />It can be used to calculate , the thermal expansion coefficient from a given temperature to 15 °C. This document can also serve to compare several aspects of density/temperature modelling and to check for compliance with and limitations in relation to existing calibration requirements. It can help in the determination of specific necessities for the grouping of fuels into common product family classes, also suggesting ways to treat fuels or components with an unusual behaviour. In addition, this document proposes possible steps for an internationally harmonized handling of new components coming into the market....

ASTM D664-2017 用电位滴定法测定石油产品酸值的试验方法 Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration
1.1 This test method covers procedures for the determination of acidic constituents in petroleum products, lubricants, biodiesel, and blends of biodiesel. 1.1.1 Test Method A—For petroleum products and lubricants soluble or nearly soluble in mixtures of toluene and propan-2-ol. It is applicable for the determination of acids whose dissociation constants in water are larger than 10–9; extremely weak acids whose dissociation constants are smaller than 10–9 do not interfere. Salts react if their hydrolysis constants are larger than 10–9. The range of acid numbers included in the precision statement is 0.1 mg/g KOH to 150 mg/g KOH. 1.1.2 Test Method B—Developed specifically for biodiesel and biodiesel blends with low acidity and slightly different solubility. This test method requires the use of an automatic titrator with automatic endpoint-seeking capability. Note 1: In new and used oils, the constituents that may be considered to have acidic characteristics include organic and inorganic acids, esters, phenolic compounds, lactones, resins, salts of heavy metals, salts of ammonia and other weak bases, acid salts of polybasic acids, and addition agents such as inhibitors and detergents. 1.2 The test method may be used to indicate relative changes that occur in oil during use under oxidizing conditions regardless of the color or other properties of the resulting oil. Although the titration is made under definite equilibrium conditions, the test method is not intended to measure an absolute acidic property that can be used to predict performance of oil under service conditions. No general relationship between bearing corrosion and acid number is known. Note 2: The acid number obtained by this standard may or may not be numerically the same as that obtained in accordance with Test Methods D974 and D3339. There has not been any attempt to correlate this method with other non-titration...
