P3TF22, P3TF30 and P3TF35 are being been cancelled by GE and replaced with P3TF52 classes A, B and C.  The specification that defines the acceptance criteria for P3TF52 is P29TF82, class A, B and C.

When the DFO comes out it will be DFO-P29TF82.

I don’t blame you for being a bit confused.

The above does not cover P3TF42 (Ti forging Multizone).  This spec is also cancelled and replaced by P29TF82, Class D.  Socomate instrument is not approved for Class D as it must be approved as an instrument/recorder combination (we are working on it).

P3TF31 is not cancelled by the above spec and the USPC-3100 will show up on DFO-P3TF31.

P3TF15 and P3TF34 are also GE specs not cancelled by the above but they do not require a DFO.
