An integral part of this PT 25/9A protocol are methodical instructions with possible participant´s comments and tabulated results. The results will be processed under a code number only so the participant´s identity may not be disclosed.

The protocol PT 25/9A and PT programme (including time schedule) is also available online for download at our homepage:

Please send the filled-out form (as Microsoft Word file) as attachment to our e-mail:

The title page of the protocol, however, should be the signed (and stamped) and scanned and attached to the same e-mail, preferably in PDF format.

It is not necessary for our purposes to receive the originals in print by mail, the electronic version suffices. We also hope to save you effort and expanses in this way.
