Some guidance regarding Amateur use of circular polarization is given by IARU Region 1 in the VHF Managers Handbook. 

IARU-R1 recommend that "Looking into the direction of transmission, helical beam aerials shall have a right-hand thread."

See page 122 - 8.8.5 IARU region 1 Technical Recommendation P.1 at
