3、 for use by laboratories that make use of ASTM TestMonitoring Center (TMC)3 services (see Annex A1 Annex A4).The TMC provides reference oils and engineering and statistical services to laboratories that desireto produce test results that are statistically similar to those produced by laboratories pr

4、eviouslycalibrated by the TMC.In general, the Test Purchaser decides if a calibrated test stand is to be used. Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process. In addition, the American Petroleum Institut

5、e (API) and the Gear LubricantReview Committee of the Lubricant Review Institute (SAE International) require that a laboratory usethe TMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laborator

6、y (andhence the Test Purchaser) has an assurance that the test stand was operating at the proper level of testseverity. It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services pro

7、cess.Laboratories that choose not to use the TMC services may simply disregard these portions.ASTM International policy is to encourage the development of test procedures based on genericequipment. It is recognized that there are occasions where critical/sole-source equipment has beenapproved by the

8、 technical committee (surveillance panel/task force) and is required by the testprocedure. The technical committee that oversees the test procedure is encouraged to clearly identifyif the part is considered critical in the test procedure. If a part is deemed to be critical, ASTMencourages alternativ

9、e suppliers to be given the opportunity for consideration of supplying the criticalpart/component providing they meet the approval process set forth by the technical committee.An alternative supplier can start the process by initiating contact with the technical committee(current chairs shown on AST

10、M TMC website). The supplier should advise on the details of the partthat is intended to be supplied. The technical committee will review the request and determinefeasibility of an alternative supplier for the requested replacement critical part. In the event that areplacement critical part has been

11、 identified and proven equivalent the sole-source supplier footnoteshall be removed from the test procedure.1.
