The following general methods of test are either discussed or referred to in this publication:Low-frequency, low- and high-voltage losscharacteristic measurements. The measurement at power frequencies of power factor, dissipation factor or watts loss and capacitance or charging current; or equivalent quantities which define the electric circuit constants of the test specimen in the voltage range of approximately 80 volts to 50 kilovolts or higher. (2) Alternating-voltage corona measurements.… read more The determination of the presence of corona discharge in the test specimen, usually related to the magnitude of the applied power-frequency voltage. The presence and the severity of corona are usually determined by indirect means; for example, by the resultant increase in dielectric loss or by the measurement of high-frequency components in the current (3) Alternating-voltage distribution measurements. The measurement of the potential of the terminal electrodes and of one or more defined points between the high-and low-voltage electrodes of the test specimen, usually with applied voltage of power frequency. read less

This document describes near-field test practices for the measurement of antenna properties. It provides information on developments in near-field measurements that have occurred since the writing of IEEE Std 149-1979 (IEEE Standard Test Procedures for Antennas). This document recommends near-field measurement practices for the three principal geometries: cylindrical, planar, and spherical, and also recommends measurement practices for the calibration of probes used as reference antennas in near-field measurements

This recommended practice establishes methods of quality assessment of light field imaging based on psychophysical studies. It also defines metrics for the quality assessment and establishes criteria for subjective assessment of light field imaging, including human factors and judgments, and identifies and quantifies quality degradation including the impact of visual contents, camera settings, compression distortion, interpolation distortion by intermediate view rendering, and structural… read more distortion. The recommended practice addresses a series of visual phenomena that can degrade visualization specifically for light field imaging. Visual environment characteristics and viewing conditions are also part of the scope of the standard, including viewing distance, viewer position, viewing freedom, and display characteristics. read less

This document describes near-field test practices for the measurement of antenna properties. It is written for the person responsible or otherwise involved in operating the test system. It recommends procedures for testing and documenting the quality of the near field system, for calibration of the system, for carrying out the antenna measurements, and for delivering the measurement data in a useful format to the end user. The document defines useful antenna metrics, describes different types… read more of test ranges with a brief introduction to the theory and equipment used. It reviews methods of characterising and operating antenna measurement ranges. Issues related to uncertainty analysis, anechoic chamber layout, probe calibration, full probe compensation, echo reduction techniques and use of non-orthogonal expansion functions in the Near-Field to Far-Field transformation are also discussed. read less

Magnetic fields of analog and digital telephone receivers, as well as non-traditional telephone receivers, such as wireless devices, may be objectively measured using this standard. Receivers not connected to a telephone may be evaluated as well. Measurement of static fields, such as those created by permanent magnets, is not covered. The methodology described in this standard is suitable for measurements in the range of 100 Hz to 10 000 Hz.
