适用范围：This part of IEC 62333 provides characterization of parameters for electromagnetic noisesuppression sheet (NSS) for digital devices and equipment used in a frequency rangebetween 30 MHz to 30 GHz. Guidance is given for uniform presentation of the properties ofnoise suppression sheet, intended for use in manufacturers and users technical data. NSSsuppresses noise at its source, rather than absorbing noise at a distance. Therefore NSS isdistinguished from RF wave absorbers used in free space.This standard addresses the following purposes of NSS manufacturers and users:– it assists users in understanding the published technical data in catalogues;– it guides users in selecting the most preferable NSS for each application;– it establishes measurement benchmarking for manufacturers of performance in newdevelopment of NSS; and– it maintains high reliability of NSS and applied products.The numerical values given in this standard are typical values of parameters (properties) ofthe related NSS. The purpose of NSS testing is the benchmarking of materials. Predictions ofspecific device performance values are not always easy or even possible.Every detailed material and NSS specification should be agreed between the user and themanufacturer.
