5. August 2018 Workgroup Activities
Participants and venues
OFITE conference room (6 members)
Conference call (6 members)
Key Activities
Team discussed testing methods used in Phase 1
Identified that one main source of uncertainty may come from the calibration of the testing equipment
Use of standardized material to isolate testing related factors from cement sample related factors

6. April 2018 Workgroup Activities
Key Activities
Two materials have been identified: Aluminum (E = 10 Mpsi; v=0.33) and Delrin (E < 0.5 Mpsi)
A third material has been looked for in the between, with no success
It has been proposed to serialize the calibration sample for further use: The objective could be to standardize the calibration of the testing equipment
Calibration samples would be needed for all plug size
Size received range from 1-in diameter to 6-in diameter
The lab have provided with the size of the plugs they can test

7. August 2018 Workgroup Activities
Key activities:
Second source of uncertainty could come from the parallelism and perpendicularity of the plugs
Third source of uncertainty could come from the sample saturation
It has been proposed to prepare a listing of the information to be provided on a test for comparison purposes.
