This draft of Egyptian standard specifies requirements for bearing metals based on tin casting alloys for multilayer plain bearings. The chemical composition and material properties refer to the original unprocessed material and are measured on representative samples. Testing results on final bearings can differ due to the influence of bearing production. Therefore, it is not intended that these results be compared with data given in ISO 4381:2011.
Worth mentioning is that this draft standard adopts the technical content of ISO 4381:2011 (confirmed in 2018)
Plain bearings (ICS code(s): 21.100.10); Lead, zinc, tin and their alloys (ICS code(s): 77.120.60)
