John IP ratings should be evaluated and tested in accordance to IEC60529. Your end-product luminaire standard may not require an IP rating depending on the construction and voltage/current levels involved. Have a great Labor Day weekend, Peter

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.
