Note: Greg Harper dated 7/2/15:
The nameplate example does not encompass the actual explosion-proof rating such as Class I, Division I, etc.
During the EASA meeting, I conversed with Mr. Liu regarding the necessity for varied temperature codes at distinct ambient temperatures. A copy of the HHI nameplate was also dispatched as a reference. It appears to be the former nameplate. Kindly resubmit the corrected version.
