This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
NOTE 1 - Examples for electrical relays in the sense of this document include electromechanical relays, reed relays, reed contacts, reed switches, solid state relays, time relays and technology combinations of these.
This document defines a standard test method for thermoelectric electromotive force (e.m.f.).
NOTE 2 - If different metals are attached at both ends and the temperatures where the metals are connected are different, then a current will flow in one direction in the circuit. The electromotive force that causes this current is called thermoelectromotive force
