Preparation of Apparatus8.1 Air Box Temperature Limiting DeviceAfter initial rig installation, preset the oven air temperature limit

32、to 400F (204 C).This can be achieved by placing the insulated oven cover in position on the rig and installing the air temperature sensor at apenetration depth of 3 in. (75 mm) below the top inner surface of the cover. Switch on the heaters and circulating fan. Adjust thetemperature control device t

33、o deactivate the heaters when the air temperature reaches 400F (204 C). This oven temperature limitmay later be reduced as outlined in 10.3 to meet rig heat-up requirements.8.2 Temperature Recording and Controlling InstrumentationSince this test procedure is extremely sensitive to temperature,it is

34、necessary to maintain a periodic check upon the accuracy of all items related to temperature measurement and control.Therefore, immediately after the installation of a new test rig, and before every set of reference tests, the instrumentation used tomeasure and record the air and oil temperatures sh

35、all be calibrated against known standards traceable to NIST.22For instance, theoil temperature thermocouple and indicating controller shall be calibrated. This can be accomplished by immersing the tip of theprobe into an auxiliary temperature-controlled oil bath equipped with a stirrer.The bath temp

36、erature shall be set accurately at 325F(162.8 C) and the test measuring equipment shall be confirmed to be accurate prior to testing.8.3 Gear CaseUsing the organic cleaning agent (see 7.3), clean the gear case, vent tube, vent tube baffle, retainer bushings,seal sleeves, case cover plate, seal plate

37、, nuts, studs, flat washers, baffle plate, spacer bushings, bearing bushings and clamp, keys,shaft ends, shaft nuts, and catalysts. Nylon bristle brushes, steel brushes, and long pipe cleaners can be used to aid cleaning. Donot use any copper or copper-containing brushes or material as a cleaning me

38、dium. Following the cleaning procedure with anorganic cleaning agent, wash parts thoroughly with cleaning solvent (see 7.5), and finally with a volatile hydrocarbon solvent (see7.6 or 7.7), to facilitate air drying. Allow parts to air dry.8.4 Test GearsThoroughly clean the test gears with cleaning s

39、olvent (see 7.5). Carefully examine the gear teeth for nicks andburrs. Do not use gears with major imperfections. Redress minor gear teeth imperfections with a fine stone or file. After finalexamination, wash gears once more with cleaning solvent and finally with a volatile hydrocarbon solvent, to f

40、acilitate air drying.Allow gears to air dry.8.4.1 Prepare each gear with new Screen-Kut silicon carbide C-180 paper.11,23Place a new piece of silicon carbide paper ona solid surface that has a thickness greater than or equal to12 in. (12.7 mm). Saturate the entire silicon carbide paper with cleaning

41、solvent (see 7.5). Use one new piece of silicon carbide paper per gear side, using both sides of the silicon carbide paper asnecessary. Sand both sides of the test gears, with the required gear holder apparatus (6.1.16) on the silicon carbide paper, usinga figure eight motion. Do not apply a downwar

42、d force to the gear holder while sanding. Sand the gears until the manufacturersmachining marks are removed. After final examination, wash gears once more with cleaning solvent (see 7.5) and finally with avolatile hydrocarbon solvent (see 7.6 or 7.7), to facilitate air drying. Allow gears to air dry

43、. If the gears are not to be usedimmediately, wrap them in a paper towel and Nox-Rust paper.11,248.4.1.1 Discard the test gears if not used within 24 h after polishing is completed.8.5 Test BearingPrior to installation, wash the test bearing first with cleaning solvent (see 7.5), and finally with a

44、volatilehydrocarbon solvent, to facilitate drying. Allow the bearing to air dry.8.6 Copper Catalyst:8.6.1 Notch one strip for purpose of identification. The notch shall be triangular in shape centered on the long side of the strip.Sides of the triangular notch shall be equal and approximately 0.2 in

45、. (approximately 5 mm) in length.8.6.2 Polish both catalyst strips on all six sides with Screen-Kut silicon carbide C-180 paper.11 ,23Use either a new piece ofScreen-Kut or one retained from the gear polishing procedure described in 8.4.1.8.6.3 Wipe both catalyst strips with absorbent cotton pads mo

46、istened with cleaning solvent (see 7.5), and wash with a volatilehydrocarbon solvent, to facilitate drying. Allow catalyst strips to air dry.8.6.4 Record the mass of the catalyst with the notched strip to the nearest 0.0001 g prior to installation. Handle cleaned catalyststrips with one of the follo

47、wing: new nitrile gloves, new latex gloves, tweezers, or ashless filter paper to avoid contamination ofthe catalyst surface from skin contact.21Until the next revision of this test method, the ASTM Test Monitoring Center (TMC) will update changes in this test method by means of Information Letters.I
