ASTM D6708-04 测量材料相同性质的两种试验方法间预期一致性的改进和统计学评估的标准实施规范

1.1 This practice defines statistical methodology for assessing the expected agreement between two standard test methods that purport to measure the same property of a material, and deciding if a simple linear bias correction can further improve the expected agreement. It is intended for use with results collected from an interlaboratory study meeting the requirement of Practice D 6300 or equivalent (for example, ISO 4259). The interlaboratory study must be conducted on at least ten materials that span the intersecting scopes of the test methods, and results must be obtained from at least six laboratories using each method.Note 1--Examples of standard test methods are those developed by voluntary consensus standards bodies such as ASTM, IP/BSI, DIN, AFNOR, CGSB.1.2 The statistical methodology is based on the premise that a bias correction will not be needed. In the absence of strong statistical evidence that a bias correction would result in better agreement between the two methods, a bias correction is not made. If a bias correction is required, then the parsimony principle is followed whereby a simple correction is to be favored over a more complex one.Note 2--Failure to adhere to the parsimony principle generally results in models that are over-fitted and do not perform well in practice.1.3 The bias corrections of this practice are limited to a constant correction, proportional correction or a linear (proportional + constant) correction.1.4 The bias-correction methods of this practice are method symmetric, in the sense that equivalent corrections are obtained regardless of which method is bias-corrected to match the other.1.5 A methodology is presented for establishing the 95 % confidence limit (designated by this practice as the cross-method reproducibility) for the difference between two results where each result is obtained by a different operator using different apparatus and each applying one of the two methods X and Y on identical material, where one of the methods has been appropriately bias-corrected in accordance with this practice.Note 3--Users are cautioned against applying the cross-method reproducibility as calculated from this practice to materials that are significantly different in composition from those actually studied, as the ability of this practice to detect and address sample-specific biases (see 6.8) is dependent on the materials selected for the interlaboratory study. When sample-specific biases are present, the types and ranges of samples may need to be expanded significantly from the minimum of ten as specified in this practice in order to obtain a more comprehensive and reliable 95 % confidence limits for cross method reproducibility that adequately cover the range of sample specific biases for different types of materials.1.6 This practice is intended for test methods which measure quantitative (numerical) properties of petroleum or petroleum products.1.7 Software program CompTM Version 1.0.21 (ADJ6708) performs the necessary computations prescribed by this practice.

Standard Practice for Statistical Assessment and Improvement of the Expected Agreement Between Two Test Methods that Purport to Measure the Same Property of a Material

ASTM D664-04 电位滴定法测定石油产品酸值的标准试验方法

1.1 This test method covers procedures for the determination of acidic constituents in petroleum products and lubricants soluble or nearly soluble in mixtures of toluene and propan-2-ol (Note 1). 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. Note 18212;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 an 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 an oil under service conditions. No general relationship between bearing corrosion and acid number is known. Note 28212;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 D3339.1.3 The values stated in acceptable SI units are to be regarded as the standard.1.4 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.

ASTM D7094-04(2009) 用改良的连续闭杯试验仪测量闪点的标准试验方法

The flash point temperature is one measure of the tendency of the test specimen to form a flammable mixture with air under controlled laboratory conditions. It is only one of a number of properties which must be considered in assessing the overall flammability hazard of a material. Flash point is used in shipping and safety regulations to define flammable and combustible materials and for classification purposes. This definition may vary from regulation to regulation. Consult the particular regulation involved for precise definitions of these classifications. This test method can be used to measure and describe the properties of materials in response to heat and an ignition source under controlled laboratory conditions and shall not be used to describe or appraise the fire hazard or fire risk of materials under actual fire conditions. However, results of this test method may be used as elements of a fire risk assessment, which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Flash point can also indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material, such as the contamination of lubricating oils by small amounts of diesel fuel or gasoline. This test method was designed to be more sensitive to potential contamination than Test Method D6450.1.1 This test method covers the determination of the flash point of fuels, lube oils, solvents and other liquids by a continuously closed cup tester utilizing a specimen size of 2 mL, cup size of 7 mL, with a heating rate of 2.5°C per minute. 1.1.1 Apparatus requiring a specimen size of 1 mL, cup size of 4 mL, and a heating rate of 5.5°C per minute must be run according to Test Method D6450. 1.2 This flash point test method is a dynamic method and depends on definite rates of temperature increase. It is one of the many flash point test methods available and every flash point test method, including this one, is an empirical method. Note 18212;Flash point values are not a constant physical chemical property of materials tested. They are a function of the apparatus design, the condition of the apparatus used, and the operational procedure carried out. Flash point can, therefore, only be defined in terms of a standard test method and no general valid correlation can be guaranteed between results obtained by different test methods or where different test apparatus is specified. 1.3 This test method utilizes a closed but unsealed cup with air injected into the test chamber. 1.4 This test method is suitable for testing samples with a flash point from 35 to 225°C. Note 28212;Flash point determinations below 35°C and above 225°C may be performed; however, the precision has not been determined below and above these temperatures. 1.5 If the user’s specification requires a defined flash point method other than this method, neither this method nor any other test method should be substituted for the prescribed test method without obtaining comparative data and an agreement from the specifier. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this stand......

ASTM D6045-04 自动三色法测定石油产品颜色的标准试验方法

Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because color is readily observed by the user of the product. In some cases the color may serve as an indication of the degree of refinement of the material. When the color range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. However, color is not always a reliable guide to product quality and should not be used indiscriminately in product specifications.1.1 This test method covers the automatic determination of color of a wide variety of petroleum products such as undyed motor and aviation gasoline, aviation turbine fuels, naphthas, kerosine, pharmaceutical white oils, diesel fuel oils, heating oils, and lubricating oils by the automatic tristimulus method. This test method correlates to Test Method D 156 and Test Method D 1500 as calculated by the instrumentation. Note 1 - With the appropriate sample handling, this test method would apply to petroleum waxes, but they were not used in the round robin, and the precision of this test method with regard to waxes is unknown.1.2 This test method reports results in terms of Test Method D 156 or Test Method D 1500.1.3 This test method has a one-to-one correlation for the entire range of Test Method D 1500 ASTM Color and for the range from 0 to +30 for Test Method D 156 Saybolt color.1.4 This test method does not apply to solid samples, petroleum products containing dye, and petroleum products having extreme fluorescence.1.5 This test method does not apply to cloudy samples. Such samples shall be filtered so they are clear before measuring. 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.

ASTM D483-04(2014) 石油制植物喷洒油不磺化残渣的标准试验方法

5.1 This test method is useful for distinguishing between oils that are adaptable to various types of spraying application, with a higher unsulfonated oil being required for leaf spraying as compared to dormant vegetation application. 1.1 This test method covers the determination of unsulfonated residue in plant spray oils of petroleum origin and applies only to the petroleum oil content. It provides a measure of the degree of refinement of plant spray oils by determining the extent to which the oil is attacked by 98.618201;% sulfuric acid under closely standardized conditions. Since the relationship between unsulfonated residue and the actual composition of the oil is not known, this test method should be applied only for measuring the degree of refinement and not for the determination of aromatics or olefins, or both. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.

ASTM D1319-03e1 用荧光指示剂吸附法测定液态石油产品中烃类物质的标准试验方法

The determination of the total volume % of saturates, olefins, and aromatics in petroleum fractions is important in characterizing the quality of petroleum fractions as gasoline blending components and as feeds to catalytic reforming processes. This information is also important in characterizing petroleum fractions and products from catalytic reforming and from thermal and catalytic cracking as blending components for motor and aviation fuels. This information is also important as a measure of the quality of fuels, such as specified in Specification D 1655. 1.1 This test method covers the determination of hydrocarbon types over the concentration ranges from 5 to 99 volume % aromatics, 0.3 to 55 volume % olefins, and 1 to 95 volume % saturates in petroleum fractions that distill below 315C. This test method may apply to concentrations outside these ranges, but the precision has not been determined. Samples containing dark-colored components that interfere in reading the chromatographic bands cannot be analyzed.1.2 This test method is intended for use with full boiling range products. Cooperative data have established that the precision statement does not apply to narrow boiling petroleum fractions near the 315C limit. Such samples are not eluted properly, and results are erratic.1.3 The applicability of this test method to products derived from fossil fuels other than petroleum, such as coal, shale, or tar sands, has not been determined, and the precision statement may or may not apply to such products.1.4 This test method has two precision statements depicted in tables. The first table is applicable to unleaded fuels that do not contain oxygenated blending components. It may or may not apply to automotive gasolines containing lead antiknock mixtures. The second table is applicable to oxygenate blended (for example, MTBE, ethanol) automotive spark ignition fuel samples with a concentration range of 13-40 volume percent aromatics, 4-33 volume percent olefins, and 45-68 volume percent saturates.1.5 The oxygenated blending components, methanol, ethanol, methyl-tert-butylether (MTBE), tert-amylmethylether (TAME), and ethyl-tert-butylether (ETBE), do not interfere with the determination of hydrocarbon types at concentrations normally found in commercial blends. These oxygenated components are not detected since they elute with the alcohol desorbent. Other oxygenated compounds shall be individually verified. When samples containing oxygenated blending components are analyzed, correct the results to a total-sample basis.1.6 The values stated in SI units are to be regarded as standard. Note 18212;For the determination of olefins below 0.3 volume %, other test methods are available, such as Test Method D 2710.This standard does not purport to address all of the safety concerns, if any, associated with its use.

1.1 This test method covers the use of automated vapor pressure instruments to determine the total vapor pressure exerted in vacuum by air-containing, volatile, liquid petroleum products. This test method is suitable for testing samples with boiling points above 0176;C (32176;F) that exert a vapor pressure between 7 and 130 kPa (1.0 and 18.6 psi) at 37.8176;C (100176;F) at a vapor-to-liquid ratio of 4:1. Measurements are made on liquid sample sizes in the range from 1 to 10 mL. No account is made for dissolved water in the sample.Note 18212;Samples can also be tested at other vapor-to-liquid ratios, temperatures, and pressures, but the precision and bias statements need not apply.1.1.1 Some gasoline-oxygenate blends may show a haze when cooled to 0 to 1176;C. If a haze is observed in 8.5, it shall be indicated in the reporting of results. The precision and bias statements for hazy samples have not been determined (see Note 10).1.2 This test method is suitable for calculation of the dry vapor pressure equivalent (DVPE) of gasoline and gasoline-oxygenate blends by means of a correlation equation (see 13.2). The calculated DVPE very closely approximates the dry vapor pressure that would be obtained on the same material when tested by Test Method D 4953.1.3 The values stated in SI units are regarded as standard.

ASTM D6892-03 石油产品倾点的标准试验方法(自动倾斜法)

The pour point of a petroleum product is an index of the lowest temperature of its utility for certain applications. Flow characteristics, such as pour point, can be critical for the correct operation of lubricating systems, fuel systems, and pipeline operations. Petroleum blending operations require precise measurement of the pour point. Test results from this test method can be determined at either 1 or 3°C intervals. This test method yields a pour point in a format similar to Test Method D 97 or IP 15, when the 3°C interval results are reported. Note 28212;Since some users may wish to report their results in a format similar to Test Method D 97 or IP 15 (in 3°C intervals) the precision data were derived for the 3°C intervals. For statements on bias relative to Test Method D 97 or IP 15, see the research report. This test method has comparable repeatability and better reproducibility relative to Test Method D 97 or IP 15 as measured in the 1998 interlaboratory program.5 FIG. 1 Schematic of Cooling/Heating Block and Cooling Circulating Bath1.1 This test method covers the determination of the pour point of petroleum products by an automatic instrument that tilts the test jar to detect movement of the surface of the test specimen with an optical device, after being removed from a regulated, stepped-bath cooling jacket.1.2 This test method is designed to cover the range of temperatures from -57 to +51176lC; however, the range of temperatures included in the 1998 interlaboratory test program only covered the temperature range from -51 to -11176;C.1.3 Test results from this test method can be determined at either 1 or 3176;C testing intervals.1.4 This test method is not intended for use with crude oils.Note 18212;The applicability of this test method on residual fuel samples has not been verified. For further information on the applicability, refer to 1.4.1.5 The values stated in SI units are regarded as standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.
