          This standard applies to surge protectors for application on multi-conductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to 1000 V rms, or 1200 V dc. These surge protectors are intended to limit voltage surges, current surges, or both.<br />\n
          This standard is not intended to cover individual device components. Installation of all surge protectors SPDs) must be in conformance with the requirements of applicable local and national electrical codes. Specifically excluded from this standard are protectors for low-voltage power circuit applications.<br />\n
          The surge protectors covered by this standard are to be tested by means of the connections or terminations that are used when the surge protector is installed in the field. For surge protectors that are intended to be used with a base or connector, that base or connector shall be part of the tests.<br />\n

          This revision will add new technology and devices and will assist the user in the specification and use of these data, signaling and communication devices. Information will be added on a Multiport SPD and will harmonize with C62.36.

          Surge protectors for application on multiconductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to 1000 V rms or 1200 V dc are covered. These surge protectors are multiple-component series or parallel combinations of one or more nonlinear elements and zero or more linear elements. The tables of typical performance values provide a means of comparison among various surge<br />\n

          \t\t\t\t<br />\n
          This standard applies to surge protectors for application on multi-conductor and coaxial, balanced or unbalanced, data, communications, and signaling circuits with voltages less than or equal to 1000 V rms, or 1200 V dc. These surge protectors are intended to limit voltage surges, current surges, or both.<br />\n
          This standard is not intended to cover individual device components. Installation of all surge protectors SPDs) must be in conformance with the requirements of applicable local and national electrical codes. Specifically excluded from this standard are protectors for low-voltage power circuit applications.<br />\n
          The surge protectors covered by this standard are to be tested by means of the connections or terminations that are used when the surge protector is installed in the field. For surge protectors that are intended to be used with a base or connector, that base or connector shall be part of the tests.<br />\n
          The tables of typical performance values of this standard provide a means of comparison among various surge protectors. They also provide a common engineering language beneficial to the user and manufacturer of surge protectors used in low-voltage data, communications, and signaling circuits.<br />\n
          This revision will add new technology and devices and will assist the user in the specification and use of these data, signaling and communication devices. Information will be added on a Multiport SPD and will harmonize with C62.36.

          Revision Standard - Inactive-Withdrawn.<br />\n

          \t\t\t\t<br />\n
          The purpose of this standard is threefold:1) To define the basic requirements of a test circuit which can be used to measure longitudinal balance. This test circuit will be capable of yielding consistent and repeatable test results.; 2) To define test conditions to be established while using the test circuit. Standard test conditions are considered vital for obtaining consistent results from a suitable circuit.; 3) To describe standard test procedures to be followed when the test circuit is operated. This standard specifies the elements of the test circuit only in general terms to allow considerable freedom when a test set is being designed. It thereby precludes the possibility that only one set of circuit elements will be capable of meeting the standard. This standard is based on a resistive test circuit, although pure resistance is not essential. Resistive elements are specified because they are generally considered easy to duplicate and balance. Repeatable and consistent balance numbers are the object of issuing this standard. Balance circuits are used at frequencies extending well into the megahertz range and there may be a need for measuring longitudinal balance at high frequencies. The definition of degree of longitudinal balance and the general configuration of the driving test circuit given in this standard are applicable at all frequencies. However, the test circuit impedances and other requirements for measurement outside the voice band are beyond the scope of this standard.

          Revision Standard - Inactive-Withdrawn.<br />\n
          The basic requirements for a test circuit that can be used to measure longitudinal balance are defined. Resistive elements are specified because they are generally considered easy to duplicate and balance. Standard test conditions and procedures are established.<br />\n
          \t\t\t\t<br />\n
          The purpose of this standard is threefold:1) To define the basic requirements of a test circuit which can be used to measure longitudinal balance. This test circuit will be capable of yielding consistent and repeatable test results.; 2) To define test conditions to be established while using the test circuit. Standard test conditions are considered vital for obtaining consistent results from a suitable circuit.; 3) To describe standard test procedures to be followed when the test circuit is operated. This standard specifies the elements of the test circuit only in general terms to allow considerable freedom when a test set is being designed. It thereby precludes the possibility that only one set of circuit elements will be capable of meeting the standard. This standard is based on a resistive test circuit, although pure resistance is not essential. Resistive elements are specified because they are generally considered easy to duplicate and balance. Repeatable and consistent balance numbers are the object of issuing this standard. Balance circuits are used at frequencies extending well into the megahertz range and there may be a need for measuring longitudinal balance at high frequencies. The definition of degree of longitudinal balance and the general configuration of the driving test circuit given in this standard are applicable at all frequencies. However, the test circuit impedances and other requirements for measurement outside the voice band are beyond the scope of this standard.
