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

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.
