This standard specifies the additional requirements to be met, and the additional parameters whose values are to be declared by the manufacturer, in respect of interruptions to, and alternating components (ripple) in the d.c. auxiliary energizing quantities of static measuring relays.
The requirements of this standard may also apply to certain electromagnetic relays having a d.c. auxiliary energizing quantity.
SECTION TWO — REQUIREMENTS CONCERNING INTERRUPTIONS TO D.C. AUXILIARY ENERGIZING QUANTITY
This section deals with interruptions to the d.c. auxiliary energizing quantity which are considered as an influencing quantity having a standard reference value but no nominal range.
