Determination of radial crushing strength ICS 77.160 H72 National Standards of People's Republic of China Replacing GB/T 6804-2002 Sintered metal bushing Determination of radial crushing strength (ISO 2739.2006, MOD) Posted 2008-08-11 2009-02-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis revised standard adopts ISO 2739.2006 "sintered metal bushing radial crushing strength was measured." This standard and ISO 2739.2006 Main technical differences and editorial changes as follows. --- Increasing the specific requirements for specimen measurements, including measuring utensils and measurement methods; --- Increasing the numerical rounding rules; --- Remove the ISO 2739.2006 in the preface; --- With a decimal symbol instead of a decimal point ",". ","; --- Because Table 1 "1MPa = 1N/m2" there is an error, so delete the entry. This standard is GB/T 6804-2002 "Sintered metal bushes - Determination of radial crushing strength," the amendment. Revision of the standard techniques Content surgery was amended as follows. --- Increasing the accuracy of the terms of the note. This standard is proposed and managed by China Machinery Industry Federation. Drafting of this standard. Beijing Institute of powder metallurgy limited liability company. The main drafters of this standard. Hao Ying, Xing Xu, Chen Wei Zhongwen governance, Huang month. This standard replaces the standards previously issued as follows. --- GB 6804-1986, GB/T 6804-2002. Sintered metal bushing Determination of radial crushing strength1 ScopeThis standard specifies the method for the determination of the cylindrical sintered metal bushing radial crushing strength. This standard applies to pure metal powder or alloy powder made of sintered bush. Sintered metal bush with ribs (sliding bearing) for measuring radial crush strength, the outer diameter of the different partial resection of the primary measurement Body part. Spherical sintered metal bearing agreement by both parties, with reference to the provisions of this standard method for determining the crushing load.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 8170-1987 numerical rounding rules Principle 3 Slowly continuously increased radial load on a cylindrical sample until a rupture, measured crush load (also known as maximum crushing load). test Sample deformation amount shall not exceed 10% of the diameter. Calculated using the radial crushing load and the cylindrical sample size relationship crushing strength.4 measuring device4.1 Test machine. capable of continuous radial load applied to the sample, and can display crush load reading device. 4.2 Measuring Tool. caliper, micrometer or other measuring range and accuracy appropriate.5 Sample5.1 sintered sample is a cylindrical (see FIG. 1), does not allow a flange, notch, groove, or an inclined horizontal hole. Both ends of the specimen are not allowed glitch. 5.2 is the result of the sample can be oiled or not oiled. 5.3 If necessary, the cylindrical sample obtained by machining; but the test results after processing the cylindrical sample may have unmachined difference.
