IFR is a 12 month license currency in EASA as well. The 6 month check is an operators proficiancy check only which applies to commercial operations and does not apply to the IF rating as such i.e. if you fail your OPC then it does not imply that your IF rating is suspended, it just means that you did not meet the requirements of your operator and need additional training to prove operator proficiancy. SAFA can not check OPC currency - this is usually checked by the authority conducting audits and checking crew documents at an operators offices.
So as was mentioned - it does not apply to your operation.- so nothing to worry about as long as your documents you need to carry on board are current.
