ISO 17786:2015 燃料用二甲醚 (DME). 高温 (105 ℃) 蒸发残留物的测定. 质量分析法

This International Standard specifies a procedure of test for high temperature (105 °C) evaporation residue in DME used as fuel by the mass analysis method. This procedure is applicable to determine the amount of high temperature (105 °C) evaporation residue up to the value specified in ISO 16861. Several tests can be applied to determine amount of evaporation residue in liquefied products. Among them, this International Standard specifies the method that has detection limit sufficient for a DME specification in ISO 16861, using less resource compared to other methods. When more precise quantitative test is required, use of ISO 13757 instead of this International Standard is recommended. Because of the procedure applied, the evaporation residue which has a boiling point lower than 105 °C will not be determined. NOTE The precision of this method has been studied for a limited set of samples and content levels by a limited amount of labs. It allows establishment of a quality specification of DME but cannot be considered as a full precision determination in line with the usual statistical methodology as in ISO 4259.

EN 16136:2015 汽车燃料 无铅汽油中锰和铁含量的测定 电感耦合等离子体发射光谱法（ICP OES）法

This European Standard specifies a method based on inductively coupled plasma optical emission spectrometry (ICP OES) for the determination of manganese content from about 0,5 mg/l to about 7,5 mg/l and of iron content from about 1,4 mg/l to about 6,0 mg/l in unleaded petrol containing up to 3,7 % (m/m) oxygen. WARNING - The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. NOTE 1 Manganese as MMT and iron as ferrocene are added to petrol to increase anti-knock properties. NOTE 2 Solutions of MMT in petrol are unstable when exposed to light. Low and erratic results are expected if petrol samples are exposed to light prior the analysis. Iron and manganese contents higher than 6,0 mg/l and 7,5 mg/l respectively may be measured after preliminary dilution of the sample with a suitable solvent. However, the precision has not been established for such a procedure. Further work regarding automotive ethanol (E85) fuel is on-going in CEN. NOTE 3 For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction (µ) and the volume fraction () of a material respectively.

This procedure is applicable to determine the amount of methanol, CO, CO2, methyl formate, ethyl methyl ether, and hydrocarbons up to C4, up to the value specified in ISO 16861. NOTE The precision of this method has been studied for a limited set of samples and content levels by a limited number of labs.

This International Standard specifies a procedure of test for the amount of water content in DME used as fuel by the Karl Fischer titration method. This procedure is applicable to determine the amount of water up to the value specified in ISO 16861. This test method is intended for use with commercially available coulometric (or volumetric) Karl Fischer reagents and for the determination of water in DME additives, lube oils, base oils, automatic transmission fluids, hydrocarbon solvents, and other petroleum products. By proper choice of the sample size, this test method can be used to determine water from mg/kg (ppm) to percent level concentrations. NOTE The precision of this method has been studied for a limited set of samples and content levels by a limited amount of labs. It allows establishment of a quality specification of DME but cannot be considered as a full precision determination in line with the usual statistical methodology as in ISO 4259.

ASTM D7901-14b 用作燃料的二甲醚的标准规格

1.1 This specification covers dimethyl ether (DME) for use as a fuel in engines specifically designed or modified for DME and for blending with liquefied petroleum gas (LPG). This specification is for use by manufacturers of dimethyl ether, by engine developers of purpose-built engines, in contracts for the purchase of DME for fuel purposes, and for the guidance of consumers of this type of fuel. Note 1: The generation and dissipation of static electricity can create problems in the handling of DME. For more information on the subject, see Guide D4865. 1.2 The values stated in SI units are to be regarded as standard. Units in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice applies to the blending of automotive spark-ignition engine fuels with ethanol concentrations greater than those suitable for conventional-fuel vehicles and less than the minimum ethanol content specification limits of Specification D5798. These mid-level ethanol fuel blends are for use in flexible-fuel vehicles and are sometimes referred to at retail as “Ethanol Flex Fuel.” 1.2 These mid-level ethanol fuel blends are only suitable for use in ground flexible-fuel vehicles equipped with spark-ignition engines. Flexible-fuel vehicles are designed to operate on gasoline or gasoline-ethanol blends that meet the requirements of Specification D4814, ethanol fuel blends that meet the requirements of Specification D5798, or any combination of these. In the United States, these vehicles are certified by the U.S. EPA as emissions compliant with these types of fuels. 1.3 The mid-level ethanol fuel blend shall be blended from either: 1.3.1 Denatured fuel ethanol conforming to the requirements of Specification D4806 with a reduced limit on inorganic chloride content that will ensure no more than 1 mg/kg inorganic chloride in the finished fuel and from spark-ignition engine fuel conforming to Specification D4814 (often at a distribution terminal or bulk plant), or 1.3.2 Ethanol fuel blends conforming to Specification D5798 and from spark-ignition engine fuel conforming to Specification D4814 (often at a retail site). 1.4 This practice describes the required procedures for blending various mid-level ethanol fuel blends for flexible-fuel vehicles at the bulk distribution point or retail/commercial delivery site. These requirements may be applied at other points in the production and distribution system when provided by agreement between the purchaser and the supplier. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
