This standard defines the parameters to be used in the identification of contact wires used in transit systems and electric railways and railroads. This standard is intended for use in identifying contact wire by metallurgical content, electrical conductivity and agency ownership. This standard is n...

Guidelines for establishing criteria for application, performance, interchangeability, tests, life cycle costs, and safety requirements of traction power rectifier transformers are established in this standard. Set forth are the electrical, mechanical and theremal design, manufacturing, and testing ...

Communications protocols to be used for inter-unit and intra-unit serial data communications between subsystems aboard passenger trains are defined by this standard. Minimum acceptable parameters for a network that can simultaneously handle monitoring and control traffic from multiple systems are se...

The purpose of this standard is to provide minimum design requirements for supporting structures types to provide support of overhead contact systems for electrified transit. This standard is developed to govern the design and fabrication of supporting structures for OCS. It is provided to define mi...

Methods for qualifying static battery chargers, inverters and uninterruptible power supply (UPS) systems for Class 1E installations outside containment in nuclear power generating stations are described in this standard. Similar electronic equipment for use in applications outside containment, where...
