Standard Test Method for Metal Powder Skeletal Density by Helium or Nitrogen Pycnometry

SIGNIFICANCE AND USE
5.1 Both suppliers and users of metals can benefit from knowledge of the skeletal density of these materials. Results of many intermediate and final processing steps are controlled by or related to skeletal density of the metal. In addition, the performance of many sintered or cast metal structures may be predicted from the skeletal density of the starting metal powder, for all or a portion of the finished piece.
SCOPE
1.1 This test method covers determination of skeletal density of metal powders. The test method specifies general procedures that are applicable to many commercial pycnometry instruments. The method provides specific sample outgassing procedures for listed materials. It includes additional general outgassing instructions for other metals. The ideal gas law forms the basis for all calculations.  
1.2 This test method does not include all existing procedures appropriate for outgassing metal materials. The included procedures provided acceptable results for samples analyzed during an interlaboratory study. The investigator shall determine the appropriateness of listed procedures.  
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 longstanding 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.

Standard Test Methods for Density of Compacted or Sintered Powder Metallurgy (PM) Products Using Archimedes’ Principle

SIGNIFICANCE AND USE
5.1 The volume of a complex shaped PM part cannot be measured accurately using micrometers or calipers. Since density is mass per unit volume, a precise method for measuring the volume is needed. Archimedes’ principle may be used to calculate the volume of water displaced by an immersed object. For this to be applicable to PM materials that contain surface connected porosity, the surface pores are sealed by oil impregnation or some other means.  
5.2 The green density of compacted parts or test pieces is normally determined to assist during press set-up, or for quality control purposes. It is also used for determining the compressibility of base powders, mixed powders, and premixes.  
5.3 The sintered density of sintered PM parts and sintered PM test specimens is used as a quality control measure.  
5.4 The impregnated density of sintered bearings is normally measured for quality control purposes as bearings are generally supplied and used oil-impregnated.
SCOPE
1.1 This standard describes a method for measuring the density of powder metallurgy products that usually have surface-connected porosity.  
1.2 The density of impermeable PM materials, those materials that do not gain mass when immersed in water, may be determined using Test Method B311.  
1.3 The current method is applicable to green compacts, sintered parts, and green and sintered test specimens.  
1.4 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. The values given in parentheses after SI units are provided for information only and are not considered 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.

Standard Test Method for Measuring Dimensional Changes Associated with Processing Metal Powders Intended for Die Compaction

SIGNIFICANCE AND USE
5.1 Dimensional Change When Compacting and Sintering Metal Powders:  
5.1.1 The dimensional change value obtained under specified conditions of compacting and sintering is a material characteristic inherent in the powder.  
5.1.2 The test is useful for quality control of the dimensional change of a metal powder mixture, to measure compositional and processing changes and to guide in the production of PM parts.  
5.1.3 The absolute dimensional change may be used to classify powders or differentiate one type or grade from another, to evaluate additions to a powder mixture or to measure process changes, and to guide in the design of tooling.  
5.1.4 The comparative dimensional change is mainly used as a quality control test to measure variations between a lot or shipment of metal powder and a reference powder of the same material composition.  
5.1.5 Factors known to affect size change are the base metal powder grade; type and lot; particle size distribution; level and types of additions to the base metal powder; amount and type of lubricant, green density, as well as processing conditions of the test specimen; heating rate; sintering time and temperature; sintering atmosphere; and cooling rate.  
5.2 Dimensional Change of Various PM Processing Steps:  
5.2.1 The general procedure of measuring the die or a test compact before and after a PM processing step, and calculating a percent dimensional change, is also adapted for use as an internal process evaluation test to quantify green expansion, repressing size change, heat treatment changes, or other changes in dimensions that result from a manufacturing operation.
SCOPE
1.1 This standard covers a test method that may be used to measure the sum of the changes in dimensions that occur when a metal powder is first compacted into a test specimen and then sintered.  
1.2 The dimensional change is determined by a quantitative laboratory procedure in which the arithmetic difference between the dimensions of a die cavity and the dimensions of a sintered test specimen produced from that die is calculated and expressed as a percent growth or shrinkage.  
1.3 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 stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 Metallographically Estimating the Observed Case Depth of Ferrous Powder Metallurgy (PM) Parts

SIGNIFICANCE AND USE
5.1 The engineering function of many PM parts may require an exterior portion of the part to have a hardened layer. Where case hardening produces a distinct transition in the microstructure, metallographic estimation of the observed case depth may be used to check the depth to which the surface has been hardened.
SCOPE
1.1 A metallographic method is described for estimating the observed case depth of ferrous powder metallurgy (PM) parts. This method may be used for all types of hardened cases where there is a discernible difference between the microstructure of the hardened surface and that of the interior of the part.  
1.2 With the exception of the values for grit size for which the U.S. standard designation is the industry standard, the values stated in SI units are to be regarded as 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.

Standard Test Methods for Flow Rate of Metal Powders Using the Carney Funnel

SIGNIFICANCE AND USE
5.1 The rate and uniformity of die cavity filling are related to flow properties, which thus influence production rates and uniformity of compacted parts.  
5.2 The ability of a powder to flow is a function of interparticle friction. As interparticle friction increases, flow is slowed. Some powders, often fine powders and lubricated powder mixtures, may not flow through the Hall funnel of Test Method B213. Nevertheless, if a larger orifice is provided, such as in the Carney funnel, a meaningful flow rate may be determined, providing specific information for certain applications.  
5.3 Test Method B213, using the Hall funnel, is the preferred method for determining the flowability of metal powders. The Carney funnel of these test methods should only be used when a powder will not flow through the Hall funnel. These test methods may also be used for comparison of several powders when some flow through the Hall funnel and some do not.  
5.4 Humidity and moisture content influence flow rate. Wet or moist powders may not flow through either the Hall or the Carney funnel.  
5.5 These test methods are based on flow of a specific mass of powder. If flow of a specific volume of powder is preferred, Test Method B855 may be used for powders that flow readily through the Hall funnel.  
5.6 These test methods may be part of the purchase agreement between powder suppliers and powder metallurgy (PM) part producers, or it can be an internal quality control test by either the supplier or the end user.
SCOPE
1.1 These test methods cover the determination of a flow rate, by use of the Carney funnel, of metal powders and powder mixtures that do not readily flow through the Hall funnel of Test Method B213.  
1.2 This is a non-destructive quantitative test performed in the laboratory.  
1.3 With the exception of the values for density and the mass used to determine density, for which the use of gram per cubic centimetre (g/cm3) and gram (g) units is the longstanding industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only, and are not considered 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.

Standard Test Methods for Surface Roughness of Powder Metallurgy (PM) Products

SIGNIFICANCE AND USE
3.1 The surface roughness of PM parts is an important characteristic in relation to factors such as their load-bearing, wear, sealing, sliding, adhesion, electrical contact, and lubricant retention properties.  
3.2 Surface roughness may also be critical for component assembly or system performance. Dimensional fit and mating surface interaction may require certain surface roughness requirements to meet performance specifications.
SCOPE
1.1 These test methods cover measuring the surface roughness of powder metallurgy (PM) products at all stages of manufacturing from green compact to fully hardened finished component.  
1.2 These test methods provide the definition and schematic of some common surface roughness parameters (Ra, Rt, and RzISO)  
1.3 This standard specifies two different standardized procedures for measuring the surface roughness of PM parts.  
1.3.1 Method 1 uses a conical stylus and a Gaussian filter.  
1.3.2 Method 2 uses a chisel (knife) edge stylus.  
1.3.3 Each test method results in a different measure of surface roughness and the results are not directly comparable.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.

Standard Test Method for Tap Density of Metal Powders and Compounds

SIGNIFICANCE AND USE
4.1 This test method covers the evaluation of the tap density physical characteristic of metal powders and related compounds. The measured tap density bears a relationship to the mass of powder that will fill a fixed volume die cavity or other container in situations where the container is tapped, vibrated, or otherwise agitated. The degree of correlation between the results of this test method and the quality of powders in use will vary with each particular application and has not been fully determined.
SCOPE
1.1 This test method specifies a method for the determination of tap density (packed density) of metal powders and compounds, that is, the density of a powder that has been tapped, to settle contents, in a container under specified conditions.  
1.2 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.  
1.3 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.
