IP 68 rating provides protection against touching with tools > 1mm and against submertion, so I do not believe that a fixture with user accessible aparts can be IP68 rated..

Even if it is not potted such that low voltage parts are accessible, can it be rated IP68? The version of IEC60529 we have does not have a lower voltage limit. The scope indicates for devices with a rated voltage not exceeding 72.5kV. Any input would be greatly appreciated. John Allen Product Safety Consulting, Inc. 605 Country Club Dr. | Stes.
