Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. The purpose of the relay is to switch and carry load currents while a minor control current through the relay coil is applied. 

The relay shall provide only two (2) operating modes: 

  • Switching Contact Open: No current flows 
  • Switching Contact Closed: Load current flows An intermediate stage is not permitted. 

Applicability. This standard applies to the following relays which are defined as follows: 

  • Relay with Normally Closed (NC) contacts: Single Pole Single Throw (SPST), NC 
  • Relay with Normally Open (NO) contacts: SPST, NO 
  • Relay with changeover contacts: Single Pole Double Throw (SPDT) 
  • Relay with multiple contacts: Double Pole Double Throw (DPDT) 
  • Solid State Relay (SSR): Constructed with electronic components which switch the load current on and off by means of Field Effect Transistors (FET) or electromechanical relays 
  • Multiple coil 
  • Latching

Remarks. This specification covers the testing of general purpose electromechanical plug-in, Printed Circuit Board (PCB), and SSRs. It presents a series of physical, environmental and durability tests, and product requirements which are used to determine the capability of a relay as specified by the part drawing.

Where a user's engineering practices or needs are not applicable to all features of this standard, it is intended that as many details as is practical be followed.
