1   Scope

  This part of [IEC 63522](/search?q=IEC%C2%A063522)
   is used for testing electromechanical elementary relays (electromechanical relays,
  reed relays, reed contacts, reed switches and technology combination of these) and
  shall evaluate their ability to perform under expected conditions of transportation,
  storage and all aspects of operational use. 
This document defines standard test methods for: 

   
      
         

1. measuring the insertion and withdrawal forces of the mating relay and socket;

2. measuring the insertion and withdrawal forces on relays with flat quickconnect terminations;

3. verifying the correct connection of flat terminals with eye lug connectors.
