9、DIN EN ISO 6506-1, Metallic materials Brinell hardness test Part 1: Test method 4DIN ISO 4384-2:2014-071 Scope This International Standard specifies parameters for the hardness testing of solid materials for plain bearings made from cast and wrought copper and aluminium alloys by machining and formi
10、ng their wrought products and ingots, and of tin-based ingots. It represents a supplement to existing International Standards on hardness testing and, therefore, includes only the extensions and restrictions for observation compared to those publications. Owing to the heterogeneous structural compos
11、ition of the majority of these bearing metals, a Brinell test is used. 2 Specimen The surface of the specimen in the test area shall be metallic bright and conditioned in such a way that a satisfactory measurement of the test impression is possible. During the preparation of the specimens, it shall
12、be ensured that the material is not heated. The testing of cast and wrought copper and aluminium alloys shall always be carried out on turned or flied and subsequently prepared surfaces, with the exception of hot-pressed parts. If the manufacturing method permits, the specimens shall be carefully po
13、lished. In the case of lead and tin alloys with a roughness value of Rt 6 m, the polishing may be carried out with abrasive paper of grain size 240 and in the case of copper and aluminium alloys with a roughness value of Rt 4 m, with abrasive paper of grain size 320 and with a suitable lubricant.
