32、x Temperature Limiting DeviceAfter initial riginstallation, preset the oven air temperature limit to 400F(204 C). This can be achieved by placing the insulated ovencover in position on the rig and installing the air temperaturesensor at a penetration depth of 3 in. (75 mm) below the topinner surface

33、 of the cover. Switch on the heaters and circulatingfan. Adjust the temperature control device to deactivate theheaters when the air temperature reaches 400F (204 C). Thisoven temperature limit may later be reduced as outlined in 10.3to meet rig heat-up requirements.8.2 Temperature Recording and Con

34、trollingInstrumentationSince this test procedure is extremely sensi-tive to temperature, it is necessary to maintain a periodic checkupon the accuracy of all items related to temperature measure-ment and control. Therefore, immediately after the installationof a new test rig, and before every set of

35、 reference tests, theinstrumentation used to measure and record the air and oiltemperatures shall be calibrated against known standardstraceable to NIST.22For instance, the oil temperature thermo-couple and indicating controller shall be calibrated. This can beaccomplished by immersing the tip of th

36、e probe into anauxiliary temperature-controlled oil bath equipped with astirrer. The bath temperature shall be set accurately at 325F(162.8 C) and the test measuring equipment shall be con-firmed to be accurate prior to testing.8.3 Gear CaseUsing the organic cleaning agent (see 7.3),clean the gear c
