Yes, 30mA plug in RCD's can be trip time tested with certain testers. The Seaward Supernova Elite has the capabilty to do this as a standalone unit. The Seaward PrimeTest 350 and PrimeTest 250 have the capability of trip testing in conjunction with the Seaward NTB -01. The RCD's are tested at 1 x Current only.
