ASTM E10-23 Standard Test Method for Brinell Hardness of Metallic Materials Active 发布日期 :  1970-01-01 实施日期 : 

4.1 The Brinell hardness test is an indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, or other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.4.2 Brinell hardness tests are considered satisfactory for acceptance testing of commercial shipments, and have been used extensively in industry for this purpose.4.3 Brinell hardness testing at a specific location on a part may not represent the physical characteristics of the whole part or end product.1.1 This test method covers the determination of the Brinell hardness of metallic materials by the Brinell indentation hardness principle. This standard provides the requirements for a Brinell testing machine and the procedures for performing Brinell hardness tests.1.2 This test method includes requirements for the use of portable Brinell hardness testing machines that measure Brinell hardness by the Brinell hardness test principle and can meet the requirements of this test method, including the direct and indirect verifications of the testing machine. Portable Brinell hardness testing machines that cannot meet the direct verification requirements and can only be verified by indirect verification requirements are covered in Test Method E110.1.3 This standard includes additional requirements in the following annexes:Verification of Brinell Hardness Testing Machines Annex A1Brinell Hardness Standardizing Machines Annex A2Standardization of Brinell Hardness Indenters Annex A3Standardization of Brinell Hardness Test Blocks Annex A41.4 This standard includes nonmandatory information in the following appendixes that relates to the Brinell hardness test:Table of Brinell Hardness Numbers Appendix X1Examples of Procedures for DeterminingBrinell Hardness Uncertainty Appendix X21.5 At the time the Brinell hardness test was developed, the force levels were specified in units of kilograms-force (kgf). Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information and much of the discussion in this standard refers to forces in kgf units.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.

4.1 Measurement of the thickness of a coating is essential to assessing its utility and cost.4.2 The coulometric method destroys the coating over a very small (about 0.1 cm2) test area. Therefore its use is limited to applications where a bare spot at the test area is acceptable or the test piece may be destroyed.1.1 This test method covers the determination of the thickness of metallic coatings by the coulometric method, also known as the anodic solution or electrochemical stripping method.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.3 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.

Two types of adhesive shall be classified according to composition. Type I which consists of two-part kits of liquid base and modified amide liquid accelerator. Type I is further subdivided into two grades: Grade 1 with low viscosity and Grade 2 with high viscosity. The other classification is Type II which consists of premixed, frozen, Type I, Grade 1 or Type I, Grade 2. Different tests shall be conducted in order to determine the following mechanical properties of the adhesives: room-temperature shear, high-temperature shear, low-temperature shear, room-temperature Shore D hardness, room-temperature T-peel, and outgassing characteristics such as total mass loss and vacuum condensable material.1.1 The specification covers a two-part modified epoxy paste adhesive for bonding metallic and nonmetallic materials. The adhesive should be suitable for forming bonds that can withstand environmental exposure to temperatures from –184 to 82 °C [–300 to 180 °F] when exposed to an expected combination of stress, temperature, and relative humidity to be encountered in service.NOTE 1: When coordinated through the Department of Defense (DoD) and the National Aeronautics and Space Administration (NASA), this practice will be a direct replacement of MIL-A-82720 (OS), MIS-26872, and MSFC-SPEC-2037.1.2 The values stated in SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.1.3 The following precautionary statement pertains to the test method portion only, Section 8, of this specification: 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.

4.1 The ball punch deformation test is widely used to evaluate and compare the formability of metallic sheet materials. Biaxial stretching is the predominant mode of deformation occurring during the test and, therefore, the results are most often used to rate or compare materials that are to be formed mainly by stretching. However, precise correlations between the cup height as determined by this test and the formability of a sheet material under production conditions have not been established.4.2 It is recognized that the cup heights for specimens from the same sample may vary with differences in magnitude of hold-down force, lubrication, and method of end point determination. The procedures described in Sections 5, 7.1, and 7.3 will minimize these variations.1.1 This test method covers the procedure for conducting the ball punch deformation test for metallic sheet materials intended for forming applications. The test applies to specimens with thicknesses between 0.008 and 0.080 in. (0.2 and 2.0 mm).NOTE 1: The ball punch deformation test is intended to replace the Olsen cup test by standardizing many of the test parameters that previously have been left to the discretion of the testing laboratory.NOTE 2: The modified Erichsen test has been standardized in Europe. The main differences between the ball punch deformation test and the Erichsen test are the diameters of the penetrator and the dies. Erichsen cup heights are given in SI units.1.2 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.1.3 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.

3.1 This practice is applicable to the calculation of stresses seen on a knee tibial component when loaded in a manner described in this practice. This practice can be used to identify the worst-case size for a particular implant. When stresses calculated using this FEA method were compared to the stresses measured at two locations on the tibial tray using physical strain gauging techniques performed at one laboratory, the difference observed was -6.8 % at one location (with the strain gauges reporting the higher stress) and 3.1 % at the other location (with the FEA method reporting a higher stress). This difference should be considered when determining the worst-case size(s) of the same implant design.3.2 The loading of tibial tray designs in vivo will, in general, differ from the loading defined in this practice. However, this practice is designed to allow for comparisons between the fatigue performance of different metallic tibial component designs, when tested under similar conditions.1.1 This practice establishes requirements and considerations for the numerical simulation of metallic orthopaedic total knee tibial components using Finite Element Analysis (FEA) techniques for the estimation of stresses and strains. This practice is only applicable to stresses below the yield strength, as provided in the material certification.1.2 Purpose—This practice establishes requirements and considerations for the development of finite element models to be used in the evaluation of metallic orthopaedic total knee tibial component designs for the purpose of prediction of the static implant stresses and strains. This procedure can be used for worst-case assessment within a series of different implant sizes of the same implant design to reduce the physical test burden. Recommended procedures for performing model checks and verification are provided as an aid to determine if the analysis follows recommended guidelines. Finally, the recommended content of an engineering report covering the mechanical simulation is presented.1.3 Limits—This practice is limited in discussion to the static structural analysis of metallic orthopaedic total knee tibial components (which excludes the prediction of fatigue strength).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.
