DIN ISO 4384 consists of the following parts, under the general title Plain bearings Hardness testing of bearing metals: Part 1: Multilayer bearing materials Part 2: Solid materials The DIN Standard corresponding to the

8、 International Standard referred to in this document is as follows: ISO 6506-1 DIN EN ISO 6506-1 Amendments This standard differs from DIN ISO 4384-1:2001-02 as follows: a) normative references have been updated; b) Table 1 “Test conditions” has been updated; Previous editions DIN ISO 4384-1: 2001-0

10、This part of ISO 4384 specifies parameters for the hardness testing of compound materials for plain bearings made from steel and bearing metal with bearing metals based on copper and aluminium, manufactured by casting, sintering or bonding. It represents a supplement to the existing ISO publications

11、 on hardness testing and, therefore, includes only the extensions and restrictions to be observed compared to those publications.The measuring method applied depends on the bearing metal layer thickness, its hardness and its structure.2 Normative referencesThe following referenced documents are indi

12、spensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 6506-1, Metallic materials Brinell hardness test Part 1: Test method3 SpecimenThe surface

13、 of the specimen in the test area shall be bright metallic and conditioned in such a way that a satisfactory measurement of the test impression is possible. During the preparation of the specimens, it shall be ensured that the material is not heated.The test surface shall be plane in accordance with

14、 ISO 6506-1.Differing to ISO 6506-1, the thickness of the test piece shall be at least four times the depth of indentation.4 ProcedureThe test conditions shall be as given in Table 1.6DIN ISO 4384-1:2014-07Table 1 Test conditionsCom-pound materialLayer thickness of bear-ing material mmTest condition

17、ample;c) test conditions and result obtained;d) all operations not specified by this part of ISO 4384, or regarded as optional;e) details of any occurrence which might have affected the result.NOTE 1 There is no general process of accurately converting Brinell hardness into other scales of hardness

18、or into tensile strength. These conversions, therefore, are intended to be avoided, unless a reliable basis for the conversion can be obtained by comparison tests.NOTE 2 Note that for anisotropic materials, for example those which have been heavily cold-worked, there will be a difference between the lengths of the two diameters of the indentation. The specification for the product can indicate limits for such differences.
