    Rationale

    Additional Fuel Flow Measurement Device 2. Additional Oil Circulation Pump and Updated Motor Specifications 1. During the October 29, 2018 Sequence VI Surveillance Panel Conference call, the panel agreed to allow the use of another model MicroMotion measurement device. The manufacturer is phasing out the current model (CMF010) specified in the procedure and model CMFS010 is a comparable replacement. Section 6.7.2 has been revised to add Model CFMS010 to the test method. 2. During the November 6, 2018 Sequence VI Surveillance Panel Conference call, the panel agreed to allow the use of another model pump for the oil recirculation pump. Model G4124B has been found suitable for this application. Also, the panel agreed to increase the motor rpm specification from 1140 1150 rpm to 1140 1170 rpm, as newer motors are being received with a higher speed rating. Finally, pump model G4214A is identified incorrectly. The correct model is G4124A. Section 6.6.5.2 has been revised to reflect these changes. SUBJECT: Alternate Procedure for Establishing Oil Level Marks As a result of an electronic ballot, the Sequence VI Surveillance Panel agreed to allow an alternate method for defining oil level marks. Section A11.1.21 has been modified and section A11.3, including footnote 22, has been added to allow use of this alternate method for determining oil level in ASTM Test Method 8114. During the March 22, 2019 Sequence VI Surveillance Panel Conference call, the panel agreed to clarify the additional break in as it relates to anomalous results. Section 10.1.18 has been revised to better describe the process and circumstances for conducting additional break-in.
