Determination of the specific surface area of powders (solids) by gas adsorption method

ASTM E542-01(2007) 实验室容量分析仪的标准校准规程

1.1 This practice covers procedures for use in the calibration of volumetric ware, in accordance with Specification E694 such as is in common use in chemical and clinical laboratories. It is based on the gravimetric determination of the quantity of water either contained or delivered, and the conversion of this value to true volume at the standard temperature of 20C by means of suitable equations and standard tables. Calibration using mercury is excluded. Calibration may be performed using alternative gravimetric methodology, provided that it is demonstrated and documented that the results obtained are equivalent to those obtained using the methodology described herein. 1.2 This practice is intended to encompass capacity ware between the limits of 0.1 cm3 and 2000 cm3. Typical products falling within the purview of this practice are burets graduated" to deliver", graduated cylinders, volumetric flasks, specific gravity flasks, measuring and dilution pipets, and transfer and capacity pipets.1.3 The procedures are not recommended for calibration of apparatus with capacities below 0.1 cm3, such as microglassware.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.

Standard Practice for Calibration of Laboratory Volumetric Apparatus

ISO 14139:2000 水文测验 应用建筑物做明渠水流测量 复合测流建筑物

This International Standard specifies the methods of measurement of flow in rivers and artificial channels, using any combination of standard weirs and/or flumes in a compound structure. For guidance on the selection of weirs and/or flumes, refer to ISO 8368. All structures can be operated in the modular flow range, but only a limited number of structures can be used in the drowned (non-modular) flow range (see clause 4). Compound weirs improve the quality of discharge measurements at low stages. The characteristics of velocity distribution are described annex A. Structures standardized for operation in the drowned (non-modular) flow range and the method of computation of flow are described in annex B. Methods and examples of flow measurement calculations are given in annex C. Compound flow-measuring structures without divide piers need in situ or model calibrations and are not covered by this International Standard.

Standard liquids for calibrating viscometers

ASTM D4741-00 高温和高剪切速率下用锥塞粘度计测量粘度的标准试验方法

1.1 This test method covers the laboratory determination of the viscosity of oils at 150oC and 1 X 106s-1 and at 100oC and 1 X 10 6s-1, using high shear rate tapered-plug viscometer models BE/C or BS/C.1.2 Newtonian calibration oils are used to adjust the working gap and for calibration of the apparatus. These calibration oils cover a range from approximately 1.8 to 5.9 mPa-s (cP) at 150oC and 4.2 to 18.9 mPa-s (cP) at 100oC. This test method should not be used for extrapolation to higher viscosities than those of the Newtonian calibration oils used for calibration of the apparatus. If it is so used, the precision statement will no longer apply.1.3 A non-Newtonian reference oil is used to check that the working conditions are correct. The exact viscosity appropriate to each batch of this oil is established by testing on a number of instruments in different laboratories. The agreed value for this reference oil may be obtained from the chairman of the Coordinating European Council (CEC) Surveillance Group for CEC L-36-A90, or from the distributor. 1.4 Applicability to products other than engine oils has not been determined in preparing this test method.1.5 This test method uses the millipascal seconds, mPa-s, as the unit of viscosity. For information, the equivalent cgs unit, centipoise, cP, is shown in parentheses.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.

Standard Test Method for Measuring Viscosity at High Temperature and High Shear Rate by Tapered-Plug Viscometer

ASTM F1995-00(2005) 利用薄膜开关剪切力测定表面安装设备(SMD)粘着强度的标准试验方法

The different combinations of SMD types, attachment medias, circuit substrates, plating options, and process variation can account for significant variation in test outcome. The SMD shear strength test is useful to manufacturers and users for determining the bond strength of the component to the membrane switch circuit.1.1 This test method covers the determination of the shear integrity of materials and procedures used to attach surface mount devices (SMD) to a membrane switch circuit.1.2 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 D4287-00(2010) 用锥板粘度计测定高速剪切粘度的标准试验方法

The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D 4958), spraying, electrostatic disk, or roll coating. This test method is suitable for all paints and varnishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment dispersions as determined by Test Method D 1210.1.1 This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s−1. 1.2 Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

Standard Test Method for High-Shear Viscosity Using a Cone/Plate Viscometer

ASTM D6606-00(2017) 用DUCK粘度计测定调色剂和清漆粘度和屈服点的标准试验方法

5.1 Actual direct measurements of apparent viscosity and stress at shear rates of interest can be useful in the practical control of ink viscosity during production and the specification acceptance between supplier and purchaser. 5.2 Use of the Duke automated viscometer provides direct measurements for viscosity and yield value versus extrapolating data points that may be far from the desired shear rates. 1.1 This test method covers the procedure for determining the viscosity of varnishes, ink vehicles, and similar liquids that are essentially nonvolatile and unreactive under ordinary room conditions using the Duke Automated high-shear rod and collar viscometer.2 1.2 The instrument in this test method is similar in principle to the falling-rod viscometer described in Test Method D4040 except that the collar is motor driven and the range of available shear stresses is considerably greater. This instrument is capable of measured and extrapolated viscosity and yield values provided the proper model is chosen for the given application. See Section 6 for the ranges of specified models. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, that may be associated with its use. It is the responsibility of the user of this standard to establish any appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4212-99 浸渍型粘度杯测定粘度的试验方法

1.1 This test method covers the determination of viscosity of paints, varnishes, lacquers, and related liquid materials by dip-type viscosity cups. This test method is recommended only for viscosity control work within one plant or laboratory and should not be used to check compliance with specifications. 1.2 Viscosity cups are designed for testing of Newtonian and near-Newtonian liquids. If the test material is non-Newtonian, that is, shear-thinning or thixotropic, another method, such as Test Methods D2196, should be used. 1.3 This standard does not purport to address all of the safety problems, 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 D4221-99(2005) 用双倍流体比重计测定粘土的分散特性的试验方法

Dispersive clays are those which normally deflocculate when exposed to water of low-salt concentration, the opposite of aggregated clays that would remain flocculated in the same soil-water system (3, 4, 7). Generally, dispersive clays are highly erosive, possibly subject to high shrink-swell potential, may have lower shear strength, and have lower permeability rates than aggregated clays. Available data (1) indicates that the test method has about 85 % reliance in predicting dispersive performance (85 % of dispersive clays show more than 35 % dispersion). Since this test method may not identify all dispersive clays, design decisions based solely on this test method may not be conservative. It is often run in conjunction with the crumb test (4, 7), the pinhole test given in Test Method D 4647, or the analysis of pore water extract (4, 7), or combination thereof, to identify possible dispersive clay behavior. Note 18212;Notwithstanding the statement on precision and bias contained in this test method; the precision of this test method is dependent on the competence of the personal performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D 3740 are generally considered capable of competent and objective testing. Users of this test method are cautioned that compliance with Practice D 3740 does not in itself ensure reliable testing. Reliable testing depends on several factors; Practice D 3740 provides a means of evaluating some of those factors.1.1 This test method, when used in conjunction with a test performed by Test Method D 422 on a duplicate soil sample, provides an indication of the natural dispersive characteristics of clay soils ().1.2 This test method is applicable only to soils with a plasticity index greater than 4 as determined in accordance with Test Method D 4318 and more than 12 % of the soil fraction finer than 5-m as determined in accordance with Test Method D 422 ().1.3 This test method is similar to Test Method D 422, except that this method covers the determination of percent of soil particles smaller than 5-m in diameter in a soil-water suspension without mechanical agitation and to which no dispersing agent has been added.1.4 The amount of particles smaller than 5-m determined by this method compared with the total amount of particles smaller than 5-m determined by Test Method D 422 is a measure of the dispersive characteristics of the soil.1.5 This test method may not identify all dispersive clay soils. Pinholes (Test Method D 4647 and crumb tests, or both, ()or the analysis of pore water extract () may be performed to help verify dispersion.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.
