          Uniform measurement procedures and techniques are provided for determining the effectiveness of electromagnetic shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable to 50 Hz and 100 GHz, respectively) for enclosures having all dimension greater than or equal to 2.0 m. The types of enclosures covered include, but are not limited to, single-shield or double-shield structures of various construction, such as bolted demountable, welded, or integral with a building; and made of materials such as steel plate, copper or aluminum sheet, screening, hardware cloth,metal foil,or shielding fabrics.<br />\n

          This standard provides uniform measurement procedures for determining the effectiveness of electromagnetic (EM) shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable down to 50 Hz and up to 100 GHz). The owner of the shielding enclosure shall provide the frequencies at which the shield will be tested, and the shielding effectiveness (SE) limits for pass/fail. This standard suggests a range of test frequencies that would provide very high confidence in the effectiveness of the shield. This standard dose not define SE limits for pass or fail.<br />\n
          The purpose of this standard is to provide the following:<br />\n
          a) A standard procedure for the measurement of the effectiveness of shielded enclosures, in a broad range of radio frequencies (RFs), including a minimum set of recommended frequencies<br />\n
          b) Identical procedures applicable to frequencies other than the standard set<br />\n

          Uniform measurement procedures and techniques are provided for determining the effectiveness of electromagnetic shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable to 50 Hz and 100 GHz, respectively) for enclosures having all dimension greater than or equal to 2.0 m. The types of enclosures covered include, but are not limited to, single-shield or double-shield structures of various construction, such as bolted demountable, welded, or integral with a building; and made of materials such as steel plate, copper or aluminum sheet, screening, hardware cloth,metal foil,or shielding fabrics.<br />\n

          This standard provides uniform measurement procedures for determining the effectiveness of electromagnetic (EM) shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable down to 50 Hz and up to 100 GHz). The owner of the shielding enclosure shall provide the frequencies at which the shield will be tested, and the shielding effectiveness (SE) limits for pass/fail. This standard suggests a range of test frequencies that would provide very high confidence in the effectiveness of the shield. This standard dose not define SE limits for pass or fail.<br />\n
          The purpose of this standard is to provide the following:<br />\n
          a) A standard procedure for the measurement of the effectiveness of shielded enclosures, in a broad range of radio frequencies (RFs), including a minimum set of recommended frequencies<br />\n
          b) Identical procedures applicable to frequencies other than the standard set<br />\n
          c) An optional measurement technique to detect the nonlinear behavior of high-permeability ferromagnetic enclosures (see Annex C)

Therefore, it identifies limitations and sources of errors of the commonly accepted techniques for measuring gaskets, and provides a basis for comparing the various accepted techniques. It encompasses measurements of the as-installed behavior of gaskets as well as manufacturing-related quality control measurements. Special attention is also given to test methods for small samples of gaskets (also above 1 GHz), correlation between different methods, and to identify possible measuring methods for near-field characterization of gaskets [as used on printed circuit board (PCB) board applications].

          This standard specifies U.S. consensus standard methods, instrumentation, and facilities for measurement of radio-frequency (RF) signals and noise emitted from electrical and electronic devices in the frequency range 9 kHz to 40 GHz. It does not include generic nor product-specific emission limits. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes. Measurement methods are included for radiated and line-conducted emissions that can be generated by a variety of devices, as described in 1.2. Definitions are provided for terms and phrases contained in the text, in which the words do not represent obvious or common usage. Measurement instrumentation, facilities, and test sites are specified and characterized, including Open Area Test Sites (OATS) and RF absorber-lined, metal chambers used for radiated emission measurement. Transverse electromagnetic wave devices used for radiated emission measurement are treated in normative Annex M. The requirements of Annex M, when such tests are performed, shall take precedence in this standard. In most cases, measurement instrumentation and calibration requirements are only generally characterized in deference to standards dedicated to these subjects, which should be used in conjunction with this standard. Requirements for operation of test samples during measurements are presented for devices in general, as well as for specific types of devices that are frequently measured. Specific requirements for emission test data recording and reporting are presented with reference to general requirements contained in documents dedicated to standard laboratory practices, which also should be used in conjunction with this standard. The main text is augmented by a series of annexes, which provide details for certain measurement methods and facilities, as well as step-by-step procedures for measurement of emissions from specific types of devices. Annex J provides an index of main text clauses by<br />\n
          device type.

          This standard specifies U.S. consensus standard methods, instrumentation, and facilities for measurement of radio-frequency (RF) signals and noise emitted from electrical and electronic devices in the frequency range 9 kHz to 40 GHz. It does not include generic nor product-specific emission limits. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes. Measurement methods are included for radiated and line-conducted emissions that can be generated by a variety of devices, as described in 1.2. Definitions are provided for terms and phrases contained in the text, in which the words do not represent obvious or common usage. Measurement instrumentation, facilities, and test sites are specified and characterized, including Open Area Test Sites (OATS) and RF absorber-lined, metal chambers used for radiated emission measurement. Transverse electromagnetic wave devices used for radiated emission measurement are treated in normative Annex M. The requirements of Annex M, when such tests are performed, shall take precedence in this standard. In most cases, measurement instrumentation and calibration requirements are only generally characterized in deference to standards dedicated to these subjects, which should be used in conjunction with this standard. Requirements for operation of test samples during measurements are presented for devices in general, as well as for specific types of devices that are frequently measured. Specific requirements for emission test data recording and reporting are presented with reference to general requirements contained in documents dedicated to standard laboratory practices, which also should be used in conjunction with this standard. The main text is augmented by a series of annexes, which provide details for certain measurement methods and facilities, as well as step-by-step procedures for measurement of emissions from specific types of devices. Annex J provides an index of main text clauses by<br />\n
          device type.

          Revision Standard - Superseded.<br />\n
          (Revision of IEEE Std 187-1990) Abstract: Spurious radiation from sound and television broadcast receivers of the superheterodyne type are possible sources of interference with other radio services. This standard describes the potential sources of spurious radiation from receivers intended for the reception of sound and television broadcast, and the measurement methods for them.<br />\n
          \t\t\t\t<br />\n
          To add new Advanced Televsion System Committee (ATSC) television standards to the present standards and clarify areas in conflict with current US Federal Communication Commission (FCC) requirements. This will include investigation of new TV receivers already being sold in the USA, including National Televsion System Committee (NTSC), ATSC and Digital Satellite System (DSS) and various combinations of these transmission methods. Finally, to expand the current standard which only applies to Table Top TV measurement setups, to include Set Top Box (STB) receivers and Rear Projection TV receivers.<br />\n
          This standard is needed to assure common measurement procedures for RF emissions in present and new technology products during the transition of NTSC analog TV to ATSC and DSS digital TV products in the USA and to ensure FCC accepts this industry need.
