3、rly equipped laboratory without outside assistance.However, the ASTM Test Monitoring Center (TMC)3provides reference oils and assessment of thetest results obtained on those oils by the laboratory (seeAnnex A1). By this means, the laboratory willknow whether their use of this test method gives resul
4、ts statistically similar to those obtained by otherlaboratories. Furthermore, various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications. For example, the American Petroleum Institute(API) imposes such a requirement, in connection with
5、several U.S. Army engine lubricating oilspecifications. Accordingly, this test method is written for use by laboratories that utilize the TMCservices. Laboratories that choose not to use those services may simply ignore those portions of thistest method that refer to the TMC. This test method may be
6、 modified by means of Information Lettersissued by the TMC. In addition, the TMC may issue supplementary memoranda related to this testmethod. Users of this test method shall contact the TMC, Attention: Administrator, to obtain the mostrecent of these information letters.1. Scope*1.1 This test metho
