The lubricants must be iden-tified by submission of an IR (infrared) reference spectrum and ICP (induc-tively coupled plasma) reference val-ues for the viscosity grades requested for approval. All test data must be generated within Siemens-approved laboratory for application-specific testing. Sie-mens will not accept test data gener-ated in an unapproved laboratory . 8 For the approval of viscosity range, oil manufacturers must guarantee that the performance level obtained in test on specific oil are consistent for that product independent of production lo-cation or viscosity grade across the vis-cosity range. In addition, the oil man-ufacturer has to warrant that the required properties do not only apply to fresh oil, but that they also do not deteriorate within permissible toler-ances through the entire period of use. The period of use for mineral oils must be at least 1,0 operating hours or two years maximum, and for synthetic oils at least 2,0 operating hours or four years maximum, assuming an av-erage oil operating temperature of 1 (8 ). Some of the challenges of the specification include extensive and ex-pensive testing of lubricants against battery of tests outlined in the specifi-cations, Shah says. Additionally , sometimes there are differences in re-sults when run at different labs. It would be helpful if these tests become standardized DIN and/or ASTM tests. The formulations tested and ap- proved by Siemens MD must be identi-cal to the oils produced commercially under the approved fluid name. Any changes to the approved formulations beyond permissible tolerances within production must be noted in writing and sent to Siemens MD. Unaccept-able changes will result in voided ap-proval and removal of the oil brand from the approved lubricant list. Tam says, Asian customers ask for Siemens MD-approved products, and commercially we have problem if we cannot deliver s
