Work Group Charge
Review and update API Spec 10D to include performance testing requirements for centralizers that are to be used in applications where they are run through restrictions that are smaller than the hole size in which they are to be set. 2

10D Document Status
Decision on Table 1 has been made, update to the working document is pending reformatting of the table itself.
Basically, limited additional sizes added to Table 1 and in-between sizes can be interpolated while sizes outside the covered range will use formula to determine value.
The tolerance on the ID of the outer pipe has been updated to improve test results as well as eliminate a loop hole for use as restriction (was ” ”, now is ” ”).
Awaiting responses of a few outstanding action items from Work Group members 9

10. 10D Work Group – document status continued:
More discussion was had on the potential impact to restoring force of running the centralizers through the restriction abruptly verses in a staged step-down method (from uncompressed OD to intermediate ID to restriction ID) versus a single step procedure (uncompressed OD directly into restriction ID):
It was decided to let a study of the effect on restoring force decide if it is warranted to put in the standard or not. If the difference in restoring force is > the 15% variation, then we will develop and include a modified test procedure for under reamed application. This will allow for stage restriction to prevent permanent deformation to the bows brought about from the high starting force condition.  10

11. 10D Work Group –
Decision was made to add the proposed reporting format to the document as an example of suggested reporting for use in the modeling software. 11

12. 10D Work Group – document status continued
Basically Table 1 is done
Definitions are close
Test procedures are ready (only awaiting impact study)
Pass Fail criterion is clear for both applications (still uses 67% data point and standard conditions)
Reporting format resolved and compatible with modeling software
We just need to word smith proposed reporting format ….. 12
