Limits of radio interference of industrial,scientific and medical (ISM) radio frequency equipment

This document establishes permissible limits for radio interference emissions generated by industrial, scientific, and medical equipment operating within specific radio frequency ranges. It defines the methodology for measuring these emissions and sets the maximum allowable levels to ensure that such devices do not cause unacceptable disruption to other radio services or communication systems. The standards cover various classes of equipment based on their operating environment and intended application, providing technical criteria for compliance testing. It outlines requirements for measurement apparatus, test sites, and procedures to guarantee consistency and reliability in evaluating electromagnetic compatibility. By setting clear boundaries for interference, the document supports the orderly development of radio frequency technologies and helps maintain the integrity of the radio spectrum. It applies to manufacturers, testing laboratories, and regulatory bodies involved in assessing the electromagnetic performance of industrial, scientific, and medical apparatus. The guidelines ensure that equipment operates harmoniously within the shared radio environment without generating excessive noise that could degrade the performance of nearby receivers or communication links.
