This paper discusses selected issues of technical diagnostics and mechanics system status monitoring. The issues presented new elements in the test of quality vibrations machines in exploitation. Investigation of machinery destruction processes accompanying every machine just after its manufacturing until its liquidation. This gives a basis for rational maintenance of machines in newly created diagnostic maintenance systems. State evaluation depending on a good model and appropriate symptoms
