A requirement of a class surveyor, recorded on an Interim Certificate of Class, that a specific measure, repair, survey, etc. must be carried out by a specified date in order for the ship to retain her class.
On a damaged ship there may be, for example, a "Condition of class now imposed" that an indented shell plate ("now temporarily repaired") must be "satisfactorily dealt with" by the next dry-docking (with due date shown). On a new LNG carrier there may be, for example, a "condition of class now imposed" that the cargo tank safety devices, high level alarms and overfill valve shutdown are to be examined and tested at the first cargo loading. When confirmed by a class surveyor to have been satisfactorily complied with, a previously-imposed condition of class will be shown on a new Interim Certificate of Class under the heading "Conditions of class now deleted".
