IEEE 1560-2005

The scope of this standard is to develop a standard method of measurement for evaluating the electromagnetic and radio frequency supression capability of filters in the frequency range of 100 Hz to 10 GHz. This will apply to EMI/RFI filters in general i.e. DC, single phase or poly phase systems rated for 600 Volts and below 1000 Amps. The method of measurement will describe general considerations, such as method of standardizing source impedance for nonlinear loads, temperature rise, attentuation measurement, components, and or derating requirements when supplying non-sinusoidal load currents and operating in matched or mismatched impedance enviroments.

The purpose of this project is to provide measurements that evaluate the performance in pratical installation, involve varying load and source impedance. These factors are not usually considered in design and performance verification testing of EMI/RFI filters. Both manufacturers and end-users could benefit from a standard that better defines the ranges and enviroment, expected effects, and test methods to verify filter attributes.

New IEEE Standard - Inactive-Reserved. 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 linear and nonlinear load impedances. H- and S-parameter measurements are introduced for modeling results. New methods for placing filter performance criteria on a filter label are also included.
