          A concise overview of shielding options for various types of interference and recommendations on shielding practices, including suggestions on terminating and grounding methods, are provided.<br />\n
          \t\t\t\t<br />\n
          This function of this guide on shielding practice for low voltage cables is to inform and familiarize the reader with shielding practice. An overview of shielding practice, systems, and test methods is provided. These tests may not be standardized; however, they are included to inform the reader and provide an overview as to what has been done to characterize shielding. This guide provides the following:<br />\n
          -An enumeration of sources of electrostatic and electromagnetic interference<br />\n
          -A review of shielding techniques to control electrostatic and electromagnetic interference for varying types oflow voltage cable uses for power, control and instrumentation services, including signal and communications cable<br />\n
          -An overview of the functional characteristics of various types of shielding<br />\n
          -Criteria for defining the most favorable techniques to combat interference<br />\n
          -Suggested tests or techniques for measuring shielding effectiveness<br />\n
          -Recommendations on shielding practices, including suggestions on terminating and grounding methods<br />\n
          The main purpose of this guide is to show how shielding can be used to minimize the effects of interference on low voltage cables. The secondary purpose is to familiarize the user with the topic of shielding and provide background information on the need for shielding. Alternate approaches will be given to achieve these purposes.

          A concise overview of shielding options for various types of interference and recommendations on shielding practices, including suggestions on terminating and grounding methods, are provided.<br />\n
          \t\t\t\t<br />\n
          This function of this guide on shielding practice for low voltage cables is to inform and familiarize the reader with shielding practice. An overview of shielding practice, systems, and test methods is provided. These tests may not be standardized; however, they are included to inform the reader and provide an overview as to what has been done to characterize shielding. This guide provides the following:<br />\n
          -An enumeration of sources of electrostatic and electromagnetic interference<br />\n
          -A review of shielding techniques to control electrostatic and electromagnetic interference for varying types oflow voltage cable uses for power, control and instrumentation services, including signal and communications cable<br />\n
          -An overview of the functional characteristics of various types of shielding<br />\n
          -Criteria for defining the most favorable techniques to combat interference<br />\n
          -Suggested tests or techniques for measuring shielding effectiveness<br />\n
          -Recommendations on shielding practices, including suggestions on terminating and grounding methods<br />\n
          The main purpose of this guide is to show how shielding can be used to minimize the effects of interference on low voltage cables. The secondary purpose is to familiarize the user with the topic of shielding and provide background information on the need for shielding. Alternate approaches will be given to achieve these purposes.

          A concise overview of shielding options for various types of interference and recommendations on shielding practices, including suggestions on terminating and grounding methods, are provided.<br />\n
          \t\t\t\t<br />\n
          This function of this guide on shielding practice for low voltage cables is to inform and familiarize the reader with shielding practice. An overview of shielding practice, systems, and test methods is provided. These tests may not be standardized; however, they are included to inform the reader and provide an overview as to what has been done to characterize shielding. This guide provides the following:<br />\n
          -An enumeration of sources of electrostatic and electromagnetic interference<br />\n
          -A review of shielding techniques to control electrostatic and electromagnetic interference for varying types oflow voltage cable uses for power, control and instrumentation services, including signal and communications cable<br />\n
          -An overview of the functional characteristics of various types of shielding<br />\n
          -Criteria for defining the most favorable techniques to combat interference<br />\n
          -Suggested tests or techniques for measuring shielding effectiveness<br />\n
          -Recommendations on shielding practices, including suggestions on terminating and grounding methods<br />\n
          The main purpose of this guide is to show how shielding can be used to minimize the effects of interference on low voltage cables. The secondary purpose is to familiarize the user with the topic of shielding and provide background information on the need for shielding. Alternate approaches will be given to achieve these purposes.

          This standard sets forth uniform methods of measurement of radio-frequency (RF) signals and noise emitted from both unintentional and intentional emitters of RF energy in the frequency range 9 kHz to 40 GHz. Methods for the measurement of radiated and ac powerline conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods cover measurement of certain devices that deliberately radiate energy, such as intentional emitters, but does not cover licensed transmitters. This standard is not intended for certification/approval of avionic equipment or for industrial, scientific, and medical (ISM) equipment. These methods apply to the measurement of individual units or systems comprised of multiple units. Additional methods may be added to this standard to fulfilll future requirements as needed. The methods used for validation of test sites, such as open area sites and absorber-lined rooms for frequencies in the range of 30 to 1000 MHz, are contained in this standard. Further work on absorber-lined room validation is under consideration. An effort has been made, wherever possible, to harmonize the measurement procedures contained herein with those in effect internationally.

          Uniform methods of measurement of radio noise emitted from low-voltage electrical and electronic equipment, including digital and other information technology equipment, in the frequency range of 9 kHz to 40 GHz are set forth. Both unintentional and certain intentional radiators are included. Methods for the measurement of radiated and powerline conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements.<br />\n

          This standard sets forth uniform methods of measurement of radio-frequency (RF) signals and noise emitted from both unintentional and intentional emitters of RF energy in the frequency range 9 kHz to 40 GHz. Methods for the measurement of radiated and ac powerline conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods cover measurement of certain devices that deliberately radiate energy, such as intentional emitters, but does not cover licensed transmitters. This standard is not intended for certification/approval of avionic equipment or for industrial, scientific, and medical (ISM) equipment. These methods apply to the measurement of individual units or systems comprised of multiple units. Additional methods may be added to this standard to fulfilll future requirements as needed. The methods used for validation of test sites, such as open area sites and absorber-lined rooms for frequencies in the range of 30 to 1000 MHz, are contained in this standard. Further work on absorber-lined room validation is under consideration. An effort has been made, wherever possible, to harmonize the measurement procedures contained herein with those in effect internationally.
