Further interpretation of the requirements is discussed for harmonisation (albeit anonymously) in the Technical Committee meetings. The document Procedure for Harmonisation acts discusses how harmonisation topics are put on the agenda and how harmonisation acts are taken. If an organisation does not agree with the Ladder CI's interpretation of a requirement, the company may ask its Ladder CI to put the subject of the difference of interpretation on the agenda for harmonisation for the next Technical Committee.
There are currently no harmonisation acts for Handbook 3.1. The harmonisation decisions for Handbook 3.0 can be found below. Those harmonisation acts have been incorporated in Handbook 3.1.
