Kries Voltage Detecting Systems are designed according to IEC 61243-5. The relevant IEC-committee has prepared a new standard IEC 62271-213:2021 which is the replacement for the IEC 61243-5.
This new standard cancels and replaces the first edition of IEC 61243-5 published in 1997 and the first edition of IEC 62271-206 published in 2011. This edition constitutes a merging of the content of IEC 61243-5 and IEC 62271-206.
Of course, Kries VDS are tested according to the new standard IEC 62271-213:2021. The new standard will be printed on the clamp label during 2021 and over the transition period also on the front cover.
