An Administration may exempt any unit which embodies features
of a novel kind from any of the provisions of the Code the application
of which might impede research into the development of such features.
Any such unit should, however, comply with safety requirements which,
in the opinion of that Administration, are adequate for the service
intended and are such as to ensure the overall safety of the unit.
The Administration which allows any such exemption should list such
exemptions on the Certificate and communicate to the Organization
the particulars, together with the reasons therefore, so that the
Organization may circulate the same to other Governments for the information
of their officers.
