We would like to use English as the ISO 27001 program language – documentation, meetings, etc. but we will refer to some documentation (in German) already in place. Will this be acceptable as references and/or evidences for the final ISO 27001 certification?
Answer: Yes, references and/or evidences in multiple languages are acceptable for the final ISO 27001 audit certification, but you should inform the certification body of this fact when arranging the certification audit. In the audit, it is certain that the certification auditor will seek evidence that people who use this documented information to carry out their activities, have the necessary fluency in the languages involved (e.g. lawyers evaluating contracts, buyers evaluating suppliers proposals, etc.), so be prepared for that.
