Full titles differ between systems:
IPC:
Arrangements for measuring or indicating electric quantities not covered by groups > Measuring form factor, i.e. quotient of root-mean-square value and arithmetic mean of instantaneous value; Measuring peak factor, i.e. quotient of maximum value and root-mean-square value
CPC:
Arrangements for measuring or indicating electric quantities not covered by groups G01R19/00 - G01R27/00 > Measuring form factor, i.e. quotient of root-mean-square value and arithmetic mean of instantaneous value; Measuring peak factor, i.e. quotient of maximum value and root-mean-square value
