IEC TR 61000-4-38:2015 has been released. The standard is titled, “Electromagnetic Compatibility (EMC) – Part 4-38: Testing and Measurement Techniques – Test, verification and calibration protocol for voltage fluctuation and flicker compliance test systems.”
“IEC TR 61000-4-38:2015(E) defines a test protocol for flicker test systems designed to perform compliance tests in accordance with IEC 61000-3-3 and IEC 61000-3-11. It is intended to provide test system manufacturers and testing laboratories with systematic methods to determine if the flicker test system meets the IEC design specifications for a wide range of voltage fluctuations and fluctuation frequencies, as specified in IEC 61000-4-15:2010, Table 5, that have been observed in product testing. It has the status of a basic EMC publication in accordance with IEC Guide 107.”
