28、changed or change only within a permissible range over a long period of time. It is on account of these properties that the materials are regarded as being especially suitable for the tribological system. As to the tribological system “plain bearing”, the compatibility between the bearing materials

29、and lubricant is of special interest and is dependent on chemical and mechanical actions.The test established in this document determines the behaviour of plain bearing materials with respect to corrosion by lubricants (lubricating oils) under static conditions, i.e. without any mechanical action ta

30、king place simultaneously.In order for such corrosion tests to be evaluated and compared, it is necessary that they be carried out in accordance with the conditions laid down in this document. Other conditions are to be indicated in detail. ISO 2017 All rights reserved vBS ISO 10129:2017BS ISO 10129

However, it is also possible to include a

37、lready known behaviour in the test reference materials or reference lubricants.5.2 The duration of the test shall be chosen, and, if necessary, extended, so that at the end of the test, definite information on the corrosion behaviour of the material tested and, possibly, of the reference material ca
