Hi Sofy, 
 IEC 1000-4-4 is an older version of the IEC EFT standard, published in 1984. In 1995 IEC 1000-4-4 was updated to IEC 61000-4-4. 
 In the update to IEC 61000-4-4 the most significant changes were: 1. The Test Levels and conditions were updated to include a 100 kHz repetition rate. 2. Updated or new details were provided for the Test equipment and coupling/decoupling networks to be used.
