ASTM D5478-13(2022) 用落针粘度计测定材料粘度的标准试验方法

1.1 These test methods cover the measurement of the viscosity of Newtonian and non-Newtonian liquids. These test methods are applicable to liquids having viscosities in the range from 5 × 10−4 Pa·s to 103 Pa·s (0.5 cP to 106 cP). The shear rate range is dependent upon the needle used and viscosity of the liquid and may vary from 10−4 s−1 to 103 s−1 . With an extension bar and applied weight, a shear rate of 104 s–1 may be achieved. 1.2 The yield stress of liquids having this property may also be determined. 1.3 These test methods consist of determining liquid viscosities of Newtonian and non-Newtonian fluids (clear or opaque) by measuring the steady-state (constant) or terminal velocities of cylindrical needles as they fall through the test liquid under the influence of gravity. Yield stresses of nonNewtonian liquids may be measured using the same procedure. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D8092-22 用微通道粘度计现场测定运动粘度的标准试验方法

1.1 This test method describes a means for measuring the kinematic viscosity of transparent and opaque liquids such as new and in-service lubricating oils using a miniature microchannel viscometer at 40 °C in the range of 12.9 mm2 /s to 174 mm2 /s 1.2 The precision has only been determined for those materials and viscosity ranges, as indicated in Section 17 on Precision and Bias. 1.3 This test method is specifically tailored to obtaining a rapid, direct, temperaturestabilized measure of the kinematic viscosity of new and in-service lubricants in the field in realtime without the use of solvents or chemical cleaning agents. The measurement takes place at 40 °C and kinematic viscosity is directly obtained. No temperature extrapolations or density corrections are necessary. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 9 on Hazards. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D7961-22 在大温度和压力范围内校准U形管密度传感器的标准实施规程

1.1 This practice outlines procedures for the calibration of U-tube density cells. It is applicable to instruments capable of determining fluid density at temperatures in the range –10 °C to 200 °C and pressures from just greater than the saturation pressure to 140 MPa. The practice refers to density cells as they are utilized to make measurements of fluids primarily in the compressed-liquid state. Examples of substances for which the density can be determined with a calibrated U-tube density meter include: crude oils, gasoline and gasoline-oxygenate blends, diesel and jet fuels, hydraulic fluids, and lubricating oils. 1.2 This practice specifies a procedure for the determination of the expanded uncertainty of the density measurement. 1.3 This practice pertains to fluids with viscosities < 1 Pa·s (1000 centipoise) at ambient conditions. 1.4 4 The values listed in SI units are regarded as the standard, unless otherwise stated. The SI unit for mass density is kilograms per cubic metre (kg·m-3 ) and can be given as grams per cubic centimetre (g·cm-3 ). 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

GSO OIML R 129-1:2022 多维测量仪器第1部分：计量技术要求

This Standard specifies the metrological and technical requirements for the type evaluation of multi-dimensional measuring instruments used to determine the dimensions and/or dimensional volume of an object for the purpose of calculating charges for postage, freight or storage. The instruments may be used in conjunction with a weighing instrument also used in the determination of charges, in which case the procedure is usually for the dimensional volume to be calculated, a conversion factor applied, and the resulting dimensional weight of the object compared to its weight to establish which quantity (the largest of measured weight or dimensional weight) will be used to determine the charges. In some cases dimensions other than volume are used for determining charges. The Recommendation also includes type evaluation procedures, verification procedures and test procedures. The requirements of This Standard apply to automatic and semi-automatic instruments, but they do not apply (for example) to simple linear measures such as tape measures. The instruments measure the length, width and height of a rectangular box and in some cases determine the dimensional volume of that box. If the object is not in the form of a rectangular box, the volume of the smallest rectangular box (by volume) which fully encloses the object is determined (see 2.2.1). Instruments may include different measurement devices, each using a different method to measure separate dimensions of an object. The instrument may measure the object whilst there is relative motion between the instrument and the object. If the multi-dimensional measuring instrument is associated with a weighing instrument, which is also used for determining the charges, the requirements for the weighing instrument are found in the following OIML Recommendations: (a) OIML R 76 Non-automatic weighing instruments [1] for non-automatic weighing instruments; and (b) OIML R 51 Automatic catchweighing instruments [2] for automatic weighing instruments. The requirements of This Standard may also be used, where applicable, for type evaluation and verification of other instruments which measure the dimensions and/or the volume of objects for applications other than for determining postage, freight or storage charges.
