Standard Test Method for Measuring Volume of Apparent Density Cup Used in Test Methods B212, B329, and B417

Standard Test Method for Measuring Volume of Apparent Density Cup Used in Test Methods B212, B329, and B417

SIGNIFICANCE AND USE
This test method enables the measurement of the volume of the apparent density cup to ensure that it complies with the specified volume of 25.00 ± 0.03 cm3  (cylindrical cup), or 16.39 ± 0.05 cm3  (square cup). Use of an out-of-specification cup will give erroneous apparent density values using the formulae in Test Methods B 212, B 329, and B 417.
SCOPE
1.1 This test method covers a procedure for measuring the volume of the apparent density cups used in Test Methods B 212, B 329, and B 417.
1.2 The apparent density cup, particularly its rim, may become worn during use, and it is recommended that the volume of the cup be checked periodically (at least every 6 months) in order to ensure that it complies with the specified volume.
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 B873-23(Test Method)
Standard Test Method for Measuring Volume of Apparent Density Cup Used in Test Methods B212, B329, and B417

SIGNIFICANCE AND USE
5.1 This test method enables the measurement of the volume of the apparent density cup to ensure that it complies with the specified volume of 25.00 cm3  ± 0.03 cm3  (cylindrical cup), or 16.39 cm3  ± 0.05 cm3  (square cup). Use of an out-of-specification cup will give erroneous apparent density values using the formulae in Test Methods B212, B329, and B417.
SCOPE
1.1 This test method covers a procedure for measuring the volume of the apparent density cups used in Test Methods B212, B329, and B417.  
1.2 The apparent density cup, particularly its rim, may become worn during use, and it is recommended that the volume of the cup be checked periodically (at least every 6 months) in order to ensure that it complies with the specified volume.  
1.3 Units—With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the long standing industry practice, the values in SI units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

Standard Test Method for Saybolt Viscosity

SIGNIFICANCE AND USE
5.1 This test method is useful in characterizing certain petroleum products, as one element in establishing uniformity of shipments and sources of supply.  
5.2 See Guide D117 for applicability to mineral oils used as electrical insulating oils.  
5.3 The Saybolt Furol viscosity is approximately one tenth the Saybolt Universal viscosity, and is recommended for characterization of petroleum products such as fuel oils and other residual materials having Saybolt Universal viscosities greater than 1000 s.  
5.4 Determination of the Saybolt Furol viscosity of bituminous materials at higher temperatures is covered by Test Method E102/E102M.
SCOPE
1.1 This test method covers the empirical procedures for determining the Saybolt Universal or Saybolt Furol viscosities of petroleum products at specified temperatures between 21 and 99 °C [70 and 210 °F]. A special procedure for waxy products is indicated.  
Note 1: Test Methods D445 and D2170/D2170M are preferred for the determination of kinematic viscosity. They require smaller samples and less time, and provide greater accuracy. Kinematic viscosities may be converted to Saybolt viscosities by use of the tables in Practice D2161. It is recommended that viscosity indexes be calculated from kinematic rather than Saybolt viscosities.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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 D445-24(Test Method)
Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)

SIGNIFICANCE AND USE
5.1 Many petroleum products, and some non-petroleum materials, are used as lubricants, and the correct operation of the equipment depends upon the appropriate viscosity of the liquid being used. In addition, the viscosity of many petroleum fuels is important for the estimation of optimum storage, handling, and operational conditions. Thus, the accurate determination of viscosity is essential to many product specifications.
SCOPE
1.1 This test method specifies a procedure for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid.  
Note 1: For the measurement of the kinematic viscosity and viscosity of bitumens, see also Test Methods D2170 and D2171.
Note 2: ISO 3104 corresponds to Test Method D445 – 03.  
1.2 The result obtained from this test method is dependent upon the behavior of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behavior). If, however, the viscosity varies significantly with the rate of shear, different results may be obtained from viscometers of different capillary diameters. The procedure and precision values for residual fuel oils, which under some conditions exhibit non-Newtonian behavior, have been included.  
1.3 The range of kinematic viscosities covered by this test method is from 0.2 mm2/s to 300 000 mm2/s (see Table A1.1) at all temperatures (see 6.3 and 6.4). The precision has only been determined for those materials, kinematic viscosity ranges and temperatures as shown in the footnotes to the precision section.  
1.4 The values stated in SI units are to be regarded as standard. The SI unit used in this test method for kinematic viscosity is mm2/s, and the SI unit used in this test method for dynamic viscosity is mPa·s. For user reference, 1 mm2/s = 10-6 m2/s = 1 cSt and 1 mPa·s = 1 cP = 0.001 Pa·s.  
1.5 WARNING—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 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.

Standard Test Method for Viscoelastic Properties of Paste Ink Vehicle Using an Oscillatory Rheometer

SIGNIFICANCE AND USE
5.1 This test method has found acceptance in the lithographic ink industry in predicting rheological behavior of a vehicle under press conditions caused by extrusion, shear-thinning rollers and dot gain recovery.  
5.2 This test method is restricted within the torque limitations and strain resolution of the rheometer used.  
5.3 Results may not be reproducible if the vehicle is not homogenous.
SCOPE
1.1 This test method covers the procedure for determining the viscoelastic properties of printing ink vehicles by measuring the G', G”, and tan delta using a controlled strain cone and plate oscillatory rheometer.  
1.2 This test method provides the flexibility of using several different types of rheometers to determine viscoelastic properties in ink vehicles.  
1.3 This test method is not intended for systems that are volatile at procedure temperatures as evaporation may occur effectively changing the percent solids before testing is finished and significantly altering the rheology.  
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.

1.2 This guide provides guidance for evaluating, selecting, and specifying general purpose balances and standard masses used in testing soil, rock, and related construction materials.  
1.3 The accuracy requirements for balances are specified in terms of the combined effect of all sources of error contributing to overall balance performance. The measurement of specific sources of error and consideration of details pertaining to balance construction has been intentionally avoided.  
1.4 This guide does not include requirements for balances having accuracies greater than those generally required in testing soil, rock, and related construction materials or for research programs or specialized testing requirements.  
1.5 This guide does not apply to nongraduated balances.  
1.6 This guide does not address the methods used to verify or quantify specific parameters dealing with balances. For a description of tests used in evaluating balance performance, see NIST Handbook 44.  
1.7 This guide is not intended to be used as a specification for the purchase of balances.
Note 1: The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS), and the International Organization of Legal Metrology (OIML) publish standards or practices that specify construction requirements as well as performance guides for balances. ASTM, OIML, and NIST publish construction standards and tolerances for standard masses.
Note 2: The terms “mass” and “determine the mass of” are used in this standard instead of the more commonly used terms “weight” and “weigh” to comply with standard metric practice. In addition, the term “standard mass(es)” is used instead of “standard weight(s)” when referring to a piece of material of known specified mass used to compare or measure the mass of other masses.  
1.8 The values states in SI units are to be regarded as standard.  
1.9 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.  
1.10 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.

ASTM D4486-23(Test Method)
Standard Test Method for Kinematic Viscosity of Volatile and Reactive Liquids

SIGNIFICANCE AND USE
5.1 Kinematic viscosity is a physical property which is of importance in the design of systems in which flowing liquids are used or handled.
SCOPE
1.1 This test method covers the measurement of kinematic viscosity of transparent, Newtonian liquids which because of their reactivity, instability, or volatility cannot be used in conventional capillary kinematic viscometers. This test method is applicable up to 2 × 10−5 N/m2 (2 atm) pressure and temperature range from −53 °C to +135 °C (−65 °F to +275 °F).  
1.1.1 For the measurement of the kinematic viscosity of other liquids, see Test Method D445. The difference between the two methods is in the viscometers. The viscometers specified in used Specification D446 are open to the atmosphere, while the viscometers in this method are sealed. When volatile liquids are measured in sealed viscometers, the density of the vapor may not be negligible compared with the density of the liquid and the working equation of the viscometer has to account for that. See Section 11 for details.  
1.2 WARNING—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 7.2, 7.3, 7.4, and Annex A1.

ASTM E3277-23a(Test Method)
Standard Test Method for Determining the Liquid or Solid State of a Material by Rheometry

SIGNIFICANCE AND USE
5.1 Shipping regulations often require the identification of a material as either a liquid or a solid. This test method may be used to make that determination for regulatory purposes. (See also Test Method D4359.)  
5.2 For liquid thermosetting resin, as cure progresses, the liquid resin becomes a solid. A thermosetting resin is more easily worked or shaped while in the liquid-like form and becomes more difficult to do so as the cure advances. The point at which the solid-like character becomes dominant is called the gel point and is considered to be the end of the period where the thermosetting resin is workable. Gel point is identified as that point where tan δ = 1 as determined in Test Method D4473.
Note 1: Gel point at ambient temperature is seldom a useful parameter. Use of this test method at the more useful elevated temperatures requires capabilities readily available but outside of 7.2.6, 7.2.7, and Section 10.  
5.3 This test method may be used in research, development, and for regulatory compliance.
SCOPE
1.1 Using rheometry, this test method determines, for regulatory purposes, whether a viscose viscous material is a liquid or a solid. Very small amounts of material (typically less than 3 g) may be used for this measurement.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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.

ABSTRACT
This test method covers the procedures for determining the viscosity of transparent liquids by bubble time method. The transparent liquids should be free from crystalline or gel particles. Test apparatus include a constant-temperature bath, standard viscosity tubes, a series of standard viscosity tubes as reference standards, timing device, tube racks, and viscosity tube corks.
SCOPE
1.1 This test method covers the determination of the viscosity in bubble seconds by timing. The bubble seconds are approximately equal to stokes for most liquids.  
1.2 The test method is applicable to transparent liquids that are free from crystalline or gel particles.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

Standard Test Method for Determining the Change in Mass of Rolled Erosion Control Products When Submerged in Water

SIGNIFICANCE AND USE
5.1 Rolled erosion control products are intended to protect seed beds from erosion and provide an environment that encourages seed germination. Maintaining a moist environment by gradually releasing absorbed moisture helps provide a beneficial growth environment. The ability of a product to absorb moisture is commonly specified. This test method can be used for quality control and to determine product conformance to a specification.  
5.2 Change in mass of RECPs submerged in water may be used to control the quality of many RECPs. Change in mass of RECPs submerged in water has not been proven to relate to field performance for all materials.  
5.3 The change in mass of RECPs submerged in water may vary considerably depending on the composition of the materials used in the product or due to inconsistency within the product. This test method enables the characterization and control of product consistency.  
5.4 This test method may be used to determine the effect of different component materials and makeup of RECPs on the change in mass when submerged in water.  
5.5 This test method may be used for acceptance testing of commercial shipments of RECPs. Comparative tests as directed in 5.6 may be advisable.  
5.6 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier shall conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the evaluation of bias. As a minimum, the two parties shall take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question. The test specimens shall be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories shall be compared using Student’s t-test for unpaired date and an acceptable probability level ch...
SCOPE
1.1 This test method measures the change in mass of a rolled erosion control product when specimens are submerged in water for a prescribed period of time. The change in mass is reported as a percentage of the original dry mass of the specimen.  
1.2 Units—The values stated in either SI units or inch-pound units [given in brackets] are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.  
1.2.1 It is common practice in the engineering/construction profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf). This practice implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated, this standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass. However, the use of balances and scales recording pounds of mass (lbf) or recording density in lbm/ft3 shall not be regarded as nonconformance with this standard.  
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this test method.  
1.3.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for t...

Standard Test Method for Viscosity by Dip-Type Viscosity Cups

SIGNIFICANCE AND USE
5.1 Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related properties of paints and related fluids.  
5.2 This type of cup is used to measure viscosity because it is easy to use, robust, and may be used in tanks, reservoirs, and reactors.  
5.3 There are other types of apparatus for measuring viscosity in the laboratory that provide better precision and bias, including the Ford viscosity cup (Test Method D1200), and the rotational viscometer (Test Methods D2196).  
5.4 Certain higher shear rate devices such as cone/plate viscometers (Test Method D4287) provide more information about sprayability, roll coatability, and other high-shear rate related properties of coatings.
SCOPE
1.1 This test method covers the determination of viscosity of paints, varnishes, lacquers, inks, and related liquid materials by dip-type viscosity cups. This test method is recommended for viscosity control work within one plant or laboratory and should be used to check compliance with specifications only when sufficient controls have been instituted to ensure adequate comparability of results.  
1.2 Viscosity cups are designed for testing of Newtonian and near-Newtonian liquids. If the test material is non-Newtonian, for example, shear-thinning or thixotropic, another method, such as Test Methods D2196, should be used. Under controlled conditions, comparisons of the viscosity of non-newtonian materials may be helpful, but viscosity determination methods using controlled shear rate or shear stress are preferred.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.
