The National Electrical Manufacturers Association (NEMA) has published NEMA 410-2015 Performance Testing for Lighting Controls and Switching Devices with Electronic Drivers and Discharge Ballasts. This standard covers the definition, measurement, and testing of characteristics relevant to the use and application of lighting controls and electronic drivers, discharge ballasts, and self-ballasted lamps. The testing guidelines were originally developed in 2011; the 2015 revision, which was released in May 2016, incorporates 347V text requirements. The document, in hard copy form, is available for purchase and it can also be downloaded for free; both options are available via the NEMA website.
