Security v8.03.404 for Part Method

Can anyone help in letting me know if it's even possible to setup a
security class based upon the "Part Class" and if so, how? I would
like to know if I have parts with a classification of "PT", that only
these parts could be viewed and edited by a specific security group.
While all part classes including the mentioned above could be viewed
and edited by all other security groups.

Thanks in advance
