IEC 60601-2-3:2012 specifies the requirements for the basic safety and essential performance of short-wave therapy equipment. Short-wave therapy equipment are defined as medical equipment for the therapeutic treatment of a patient by exposure to electric or magnetic fields produced in the frequency range of more than 13 MHz but not exceeding 45 MHz. Equipment having a rated output power not exceeding 10 W are exempted from certain requirements of this standard. This third edition cancels and replaces the second edition of IEC 60601-2-3 published in 1991 and its amendment 1 published in 1998. This edition constitutes a technical revision and has been aligned with IEC 60601-1:2005.
