    Definition
  • Provides uniform measurement procedures for determining the shielding effectiveness of electromagnetic (EM) shielding for a variety of enclosures and boxes having all dimensions between 0.1 and 2 meters in the radio frequency range not addressed by IEEE 299-2006. This standard is divided into(...)
  • 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(...)
  • Measurements of the electrical properties of naturally occurring solids are covered in the scope of this project. Not covered are methods that rely on mapping earth structure anomalies unless directly related to electrical properties. Coverage of numerical methods for forward/inverse modeling(...)
  • Covers definitions of terms, controlled test conditions, test apparatus, test methods and data presentation, all of which form the basis for establishing the energy levels of spurious emissions of mobile communication transmitters designed to generate frequency-modulated (FM) signals in the(...)
  • Test procedures for microwave field disturbance sensors to measure radio frequency (RF) radiated field strength of the fundamental frequency, harmonic frequencies, near field power flux density, and nonharmonic spurious emissions of sensors operating within the frequency range of 300 MHz to 40(...)
  • Uniform procedures for the measurement of power frequency electric and magnetic fields from alternating current (AC) overhead power lines and for the calibration of the meters used in these measurements are established. The procedures apply to the measurement of electric and magnetic fields(...)
  • Standard for Ethernet Amendment 2: Physical Layer Specifications and Management Parameters for 100 Gb/s Operation Over Backplanes and Copper Cables.
  • IEEE Standard for Ethernet Amendment 1: Physical Layer Specifications and Management Parameters for 100 Mb/s Operation over a Single Balanced Twisted Pair Cable (100BASE-T1). This standard deals with the 100BASE-T1 Physical Layer (PHY) specifications and management parameters for(...)
  • IEEE 802.19.1 specifies radio technology independent methods for coexistence among dissimilar or independently operated wireless networks operating in TVwhite space (TVWS).
  • Realistic and repeatable criteria, as well as recommended test methods, for characterizing the absorption properties of typical anechoic chamber linings applied to a metallic surface are described. Parameters and test procedures are described for the evaluation of RF absorbers to be used for(...)
  • Procedures for the measurement of electric and magnetic fields in close proximity to video display terminals (VDTs) in the frequency range of 5 Hz to 400 kHz are provided. Existing international measurement technologies and practices are adapted to achieve a consistent and harmonious VDT(...)
  • Information to assist users of gaskets in evaluating gasket measurement techniques to determine which exhibit the properties critical to the intended application, to highlight limitations and sources of error of the competing measurement techniques, and to provide a basis for comparing the(...)
  • Consensus calibration methods for electromagnetic (EM) field sensors and probes are provided. Data recording and reporting requirements are given, and methods for estimating measurement uncertainty are specified.
  • This guide provides a methodology to allocate the capacity of the system to absorb voltage fluctuations (i.e., flicker). However, it does not address how to mitigate voltage fluctuations, nor does it address how to increase the capacity of the system to absorb such disturbances. Since the(...)
  • Gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to be constructed. A method is given for the evaluation(...)
  • A listing of possible measurement goals related to characterizing quasi-static magnetic and electric fields and possible methods for their accomplishment is provided.
  • Describes the process of the measurement of the radar cross section of objects using a test range. The term "radar cross section" is defined, and the characteristics of different types of test ranges are given. The responsibilities of the test range operators are shown to involve test and(...)
  • Protocols and test procedures are specified for the measurement of the peak spatial-average SAR induced inside a simplified model of the head of users of certain handheld radio transceivers. These transceivers are intended to be used for personal wireless communications services, operate in(...)
  • This amendment addresses certain text ambiguities in IEEE Std 1528-2003 and provides CAD files for the human head model that were not included with the base standard.
  • Uniform methods of measurements of radio-frequency power-line interference filter attenuation performance in the range of 100 Hz to 10 GHz are set forth. Nonloaded and loaded attenuation measurements are presented with varying source impedance, including radiofrequency current injection with(...)
