Standard Test Methods for Determining Loose and Tapped Bulk Densities of Powders using a Graduated Cylinder (Withdrawn 2018)

Standard Test Methods for Determining Loose and Tapped Bulk Densities of Powders using a Graduated Cylinder (Withdrawn 2018)

SIGNIFICANCE AND USE
The data from the loose bulk density test can be used to estimate the size of bags, totes, small bins or hoppers for the storage of a fixed mass of powder in its loose condition. It can also be used to estimate the mass of powder that will fit in small size containers such as drums. It cannot be used to estimate powder quantities of large vessels such as silos.
Values of loose bulk density obtained using this test method should be used with caution, since they can vary considerably depending on the inital state of dispersion of the test specimen, height-to-diameter ratio of specimen in graduated cylinder, dryness of powder, and other factors.
The data from the tapped bulk density test can be used to estimate the needed volume of small containers holding a fixed mass of powder that has been compacted. An example would be a packing line where vibration is used to tamp powders into a small container for effective packing purposes.
Bulk density values can vary significantly if the particle size of the actual material to be handled is different than tested. A bulk solid consisting of large and small particles often has higher bulk densities than the fine particles by themselves. For powders, lower densities are possible if the fine particles are fluidized or aerated.
The results of this test method are most applicable to containers with volumes up to about one cubic meter. Another method (such as D 6683) should be used when considering larger silos.
Note 1—The quality of the results produced by this standard is dependent on the competence of the personnel 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/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D 3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D 3740 provides a means of ...
SCOPE
1.1 This test method covers the apparatus and procedures for determining the bulk densities of free flowing and moderately cohesive powders and granular materials up to 3.5 mm in size in their loose (Method A) and tapped (Method B) states.
1.2 This test method should be performed in a laboratory under controlled conditions of temperature and humidity.
1.3 This test method is similar to those of Test Methods B 212, D 29, and D 2854.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.
1.4.1 The procedures used to specify how data are collected/recorded or calculated in this 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 variations, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.
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.

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 Determining Mass per Unit Area of Geohazard Nettings

SIGNIFICANCE AND USE
5.1 Using a geohazard netting as a medium to retain rock particles necessitates compatibility between it and the adjacent rock. This test method measures the mass per unit area of a geohazard netting which is often specified by design engineers as an indicator of a geohazard netting’s ability to stabilize and control the movement of loose rocks. Knowing a geohazard netting’s mass per unit area is also important in analyzing the anchoring required to support the mesh at the top of a soil or rock slope.  
5.2 This test method may also be used for quality control during the manufacturing process and quality assurance that material meets project or material specifications.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
SCOPE
1.1 This test method is an index test to determine the mass per unit area of geohazard nettings. The mass per unit area is a characteristic of a geohazard netting that contributes to its ability to stabilize and control the movement of loose rocks. There are many different types of geohazard nettings which necessitates a single standard by which all geohazard nettings may be measured.  
1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered 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; the absolute and the gravitational systems. 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 (lbm) or recording density in lbm/ft3 shall not be regarded as nonconformance with this standard.  
1.2.2 The terms density and unit weight are often used interchangeably. Density is mass per unit volume, whereas, unit weight is force per unit volume. In this standard, density is given only in SI units. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.  
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 the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering data.  
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 practi...

Standard Test Method for Marsh Funnel Viscosity of Construction Slurries

SIGNIFICANCE AND USE
5.1 Viscosity is a fundamental characteristic for slurries in construction applications. The Marsh Funnel Viscosity test can be used for field quality control of slurries. Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures.
Note 1: The development of the Marsh Funnel is credited to Hallan N. Marsh of Los Angeles who published the design and use of his funnel viscometer in 1931.  
5.2 This test method allows for the assessment of the apparent viscosity of construction slurries in the laboratory and in the field. The Marsh Funnel Viscosity is not a true viscosity, it is an index value and can only be used to assess the relative viscosity of the slurry to water. Higher MFV values are obtained for slurries with higher viscosity and lower MFV values are obtained for slurries with lower viscosity.  
5.3 In this test, it is assumed that the apparent viscosity of a slurry is directly related to the flow duration through a specially shaped funnel (the Marsh Funnel).  
5.4 In slurry construction applications, the viscosity of a slurry must be maintained within a predetermined range to stabilize the surrounding soil being supported.  
5.5 The Marsh Funnel Viscosity has been widely used in drilling soil and rock for water wells and oil, gas, soil stabilization, foundation drilling, and hydraulic barrier applications.  
5.6 Inert suspended solids (such as fine sands, clays, and cement) and additives affect the viscosity of slurries. This test may be used to determine the relative effects of these and other such materials on the viscosity of a slurry.
Note 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing, sampling/inspection/etc. Us...
SCOPE
1.1 This test method provides an indirect measurement of the viscosity of construction slurries using a funnel (Marsh Funnel) and a graduated cup with specific volume marks. This test method provides an indicator of the viscosity on a routine basis. This test method has been modified from the API Recommended Practice 13B-1.  
1.2 The result determined using the method is referred to as the Marsh Funnel Viscosity. The Marsh Funnel Viscosity is an index property and is not an actual measurement of viscosity.  
1.3 This test can be performed in the laboratory or in the field to assess the Marsh Funnel Viscosity of a slurry for quality control purposes.  
1.4 Units—The values stated in either SI units or inch-pound units 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.  
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.

SCOPE
1.1 This test method covers the apparatus and procedures for determining the bulk densities of free flowing and moderately cohesive powders and granular materials up to 3.5 mm in size in their loose (Method A) and tapped (Method B) states.  
1.2 This test method should be performed in a laboratory under controlled conditions of temperature and humidity.  
1.3 This test method is similar to those of Test Methods B212, B329, B417, D29, and D2854.

SIGNIFICANCE AND USE
4.1 This guide provides those using standards related to soil, rock, and related construction materials, with a means for selecting the balance required for a particular standard.  
4.2 This guide provides those writing standards pertaining to soil, rock, and related construction materials with a means for specifying the balance capabilities required for a particular standard and for describing the balance selected in a uniform fashion.  
4.3 This guide provides agencies conducting soil, rock, and related construction materials, testing with guidance for selecting and evaluating general purpose balances and standard masses.  
4.4 This guide provides inspection organizations with criteria for evaluating general purpose balances and standard masses.
SCOPE
1.1 This guide provides minimum requirements for general-purpose scales, balances, and standard masses used in testing soil, rock, and related construction materials.  
1.2 This guide provides guidance for evaluating, selecting, and specifying general purpose scales, balances, and standard masses used in testing soil, rock, and related construction materials.  
1.3 The accuracy requirements for balances and scales 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 and scales 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 and scales. 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 and scales.
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 “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 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.  
1.9 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 D445-23(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 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.

Standard Test Method for Viscosity of Transparent Liquids by Bubble Time Method

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 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.

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...
