55 CHAPTER SUMMARY OF TEST PROCEDURE 10 A 10-ml sample is placed in a test cell, pre-heated to a specified temperature, and held at that temperature for a specified time to ensure complete solution of all components of the oil. The temperature of the cell is then lowered to the test temperature at a programmed cooling rate. The test temperature and the cooling program (profile) are determined by the nature of the sample being tested and by the test method being used.
56 NOTE Most commercial oils do not have a yield stress when tested as specified by the SAE J300 Viscosity Classification. For the complete, definitive description of the ASTM D 4684 method, see the provided Standard Test Method for Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature, Designation: D 4684, also available in the Annual Book of ASTM Standards, Volume 05.03. NOTE Nothing in this manual is intended to supersede the provisions of the ASTM test method.
57 The temperature profile for this method consists of a 1.5-hour soak at 50°C ± 1°C, a 2-hour nonlinear cool-down to the test temperature, and a 14-hour soak ± 0.02°C at the test temperature. The entire temperature profile, up to the point of measuring yield stress and viscosity, requires 17.5 hours.

Press the flashing Start Test button on the CMRV Controller front panel and proceed immediately to step 8. 8. Slide the rotor locking pin upward to its detent position, allowing the weight/hook-cage to hang free.
67 11. Repeat steps 1-10 to perform yield stress/viscosity tests for all remaining cells to be tested in order from left to right. Notes on yield stress testing Step 9 (see previous section) is required for ASTM D 3829. The ASTM D 4684 method is a pass-fail method for fresh oils. If the rotor fails to move with the weight of the 10-gram hook-cage, the oil has failed the test. However, the MRVW program permits adding of additional weights.
68 The CMRV-5000 will measure the speed of rotor rotation by timing the revolution(s) of the pulleywheel as the weight falls. NOTE The total number of rotations measured by the CMRV-5000 during the viscosity test depends on the viscosity of the sample and the values chosen in the Advanced Settings box. Default values for the Advanced Settings correspond to the specifications of the ASTM method selected for the profile. 7.

Adding a data point to the profile 2. Click the Add Point button to add the data to the profile.
84 TO delete the point click Yes. To keep the selected point(s) click No. Cooling profile limitations CMRV cooling capacity The CMRV cooling capacity changes proportionally with the temperature at which the instrument is controlling. Greater cooling capacity is achieved at warmer temperatures, and capacity decreases as temperature decreases. This makes linear rates-of-cooling impossible in relatively short time frames.
85 NOTE When the user is designing an entirely new profile “from scratch”, the test parameters will default to ASTM D 4684 specifications. Copies or modifications of standard profiles will default to the parameters associated with the ASTM method (D 3829 or D 4684). Changing test parameters To change test parameters: 1. Open the Profile Designer. 2. Select the desired profile and click the Create ..., Copy ... or Edit ... button as desired. The Profile Editor window will open. 3.

111 CHAPTER APPENDIX C — THERMOMETRY C Kinematic viscosity and temperature Kinematic viscosity is an extremely temperature-sensitive measurement a change of 1°C can sometimes lead to a viscosity change of 10 percent or more. Therefore, it is not surprising that temperature measurement and control are the most common problems encountered by laboratories performing accurate kinematic viscosity measurements.
112 ASTM thermometer tables The following tables show the ASTM thermometers available from CANNON® Instrument Company: CANNON® Mini-Rotary Viscometer CMRV-5000 Instruction & Operation Manual Version 1.
113 NOTE International shipments may be subject to special shipping regulations. ASTM D 445 — Checking the ice point Frequency To achieve an accuracy of ± 0.02°C for calibrated kinematic viscosity thermometers, a check at the ice point must be made. New thermometers should be checked monthly for the first six months, then once every six months. CANNON® Mini-Rotary Viscometer CMRV-5000 Instruction & Operation Manual Version 1.
114 Method The following text outlines procedures for checking the ice point of a thermometer. The text is adapted from: 1994 Annual Book of ASTM Standards, Volume 05.01, Method E77 ASTM Method E77 contains a detailed procedure for the measurement of ice points. The instructions listed here are specifically designed for the mercury-in-glass “kinematic viscosity” thermometers described in Table 2, and may not apply to other thermometers.
115 NBS Monograph150: Joining separated mercury columns The following text outlines procedures for joining separated mercury columns in thermometers. The text is adapted from: NBS MONOGRAPH 150 Liquid-In-Glass Thermometry Wise, Jacquelyn A. NOTE Many inquiries are received concerning separated mercury column which occur especially during shipment. Since no means of avoiding such occurrences has yet been found, some directions for joining mercury may be helpful and are described below.
116 fluid to break away from the wall of the capillary and flow down the bore to join the main column. Uniting gas bubbles Minute gas bubbles, which are sometimes found along the surface of the mercury in the thermometer bulb, may be collected by “washing” the bulb with a large gas bubble. Bring all of the mercury into the bulb as outlined in section (A). Hold the thermometer in a horizontal position and gently tap it against the hand to form a large gas bubble.
117 CHAPTER APPENDIX D — MULTI-UNIT CONFIGURATION D Introduction The CMRV-5000 instrument have been designed to permit multi-unit configurations of up to four CMRV units. Configuration is accomplished via a “daisy-chain” technique using RS-485 connections. A multi-unit interface kit containing all required items for multi-unit configuration is available from CANNON® (Catalogue # 9728-R40 for 120V units; #9728-R45 for 240V units).
118 Attach the CAT-5 cable to one of the open RS-485 ports on the first CMRV. Attach the next CAT-5 cable to the other open RS-485 port on the first CMRV, and connect the other end of the cable to an open RS485 port on the second CMRV. Continue this "daisy RS-485 connections on the CMRV chassis chain" process until the last CMRV has been connected. NOTE Each additional CMRV should be connected to the previous CMRV in the daisy-chain. Up to four CMRV units can be connected to a single computer. 5.
