GB/Z 19511-2004
ActiveIndustrial，scientific and medical equipment(ISM)--Guidelines for emission levels within the bands designated by the ITU
工业、科学和医疗设备(ISM) 国际电信联盟(ITU)指定频段内的辐射电平指南
Application Summary AI generated
This standard provides guidelines for managing electromagnetic emissions from industrial, scientific, and medical (ISM) equipment operating within frequency bands designated by the International Telecommunication Union (ITU). It is applied to ensure that ISM devices, such as RF heating equipment or medical diathermy machines, do not cause harmful interference to radio communication services sharing those bands. The standard is used by manufacturers and test laboratories to define acceptable emission levels and measurement methods for compliance with international radio regulations.
