scope:

This standard for EMC immunity requirements applies to Telecommunication Terminal Equipment (TTE) intended for use in the residential, commercial and light-industrial environment. This standard is applicable to either stand alone terminal equipment or to plug-in terminal equipment when inserted into host equipment. Immunity requirements in the frequency range 0 Hz to 400 Ghz are covered. Due to testing and performance assessment considerations some tests are specified in defined frequency bands or at selected frequencies. Equipment which fulfills the requirements at these frequencies is deemed to fulfill the requirements in the frequency renge 0 Hz to 400 Ghz for electromgenetic phenomena.
