2.3.2 Physical requirements 

Although compliance of an international application with the PCT requirements as to form and content is, as a rule, ascertained during the international phase, the EPO may check Euro-PCT applications entering the European phase for compliance with Rule 11 PCT. If the application documents do not comply with this provision, the EPO will issue a communication indicating any deficiencies and invite the applicant to correct them within a time limit of two months under Rule 58.

Since the translation filed under Rule 159(1)(a) is filed for the procedure before the EPO as designated or elected Office, the translation must comply with the physical requirements as set out in A‑III, 3 ("Physical requirements"). The requirements are in general identical with the corresponding requirements of the PCT.
