ECIA - EIA-407 - TESTING PROCEDURES FOR RELAYS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT Organization: ECIA
Date: 1978-01-01
Description: The standard is intended for relays that perform general switching functions in military and commercial systems: it is not applicable to the following electromagnetic switching devices, some of which are covered by other standards: Choppers Circuit breakers Contactors Motor-driven time-delay relays Relays associated with electric power apparatus Stepping relays Pneumatic and hydraulic relays Reed switch relays (EIA Standard RS-436) Thermal relays Solid state relays (EIA Standard RS-443) For the definition of the various relay terms cited in this publication refer to: (1) ANSI C83.16-1971 American National Standard Definitions and Terminology for Relays for Electronic Equipment.
DSF/FPREN 60255�-127 - MEASURING RELAYS AND PROTECTION EQUIPMENT -- PART 127: FUNCTIONAL REQUIREMENTS FOR OVER/UNDER VOLTAGE PROTECTION Organization: DS
Description: The standard includes specification of the protection function, measurement characteristics and time delay characteristics. This part of IEC 60255 specifies defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions.
ATIS 0100513 - FRAME RELAY DATA COMMUNICATION SERVICE -ACCESS, USER INFORMATION TRANSFER, DISENGAGEMENT, AND AVAILABILITY PERFORMANCE PARAMETERS Organization: ATIS
Date: 2003-02-01
Description: The frame relay service classes may be used to describe the information transfer phase of data networks when providing national frame relay service (either permanent virtual connection service or switched virtual connection service). Three frame relay performance parameters – frame transfer delay, frame delay jitter, and committed frame loss ratio – are used to characterize the various frame relay service classes.
UL 1008A - UL STANDARD FOR SAFETY MEDIUM-VOLTAGE TRANSFER SWITCHES - FIRST EDITION; REPRINT WITH REVISIONS THROUGH AND INCLUDING APRIL 17, 2013 Organization: UL
Date: 2012-03-30
Description: These requirements cover transfer switches together with their associated control devices including, but not limited to, voltage sensing relays, frequency sensing relays, and time delay relays. An automatic transfer switch as covered by these requirements is a device that automatically transfers a common load from a normal supply to an alternate supply in the event of failure of the normal supply, and automatically returns the load to the normal supply when the normal supply is restored.
UL 1008A OUTLINE - OUTLINE OF INVESTIGATION FOR TRANSFER SWITCH EQUIPMENT, OVER 600 VOLTS - ISSUE 1 Organization: UL
Date: 2006-08-02
Description: These requirements cover transfer switches together with their associated control devices including voltage sensing relays, frequency sensing relays, time delay relays, and the like. An automatic transfer switch as covered by these requirements is a device that automatically transfers a common load from a normal supply to an alternate supply in the event of failure of the normal supply, and automatically returns the load to the normal supply when the normal supply is restored.
UL 1008S - UL STANDARD FOR SAFETY SOLID-STATE TRANSFER SWITCHES - FIRST EDITION Organization: UL
Date: 2012-11-15
Description:   These requirements cover transfer switches together with their associated control devices including voltage sensing relays, frequency sensing relays, time delay relays, and the like.  An automatic transfer switch as covered by these requirements is a device that automatically transfers a common load from a normal supply to an alternate supply in the event of failure of the normal supply, and automatically returns the load to the normal supply when the normal supply is restored.
