5、 Lubricant ReviewCommittee of the Lubricant Review Institute(SAE International)require that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laboratory(andhence the Test Pu
6、rchaser)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 process.Laboratories that ch
7、oose 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 technical committee(surve
8、illance 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 alternative suppliers to be given the opp
9、ortunity 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 ASTM TMC website).The supplier sho
