Mr. Flanigan, EN 50140:93 is really ENV 50140:93 and EN 61000-4-3:96 does replace it with a dow of 1997-06-01 (as found in the forward of EN 61000-4-3:96). Subsequently A1 was published in Aug 98.
There was a lot of good wordsmithing between ENV 50140:93 and EN 61000-4-3:96 but no significant change EXCEPT the requirement for 900MHz pulse modulation at 200Hz was dropped. If you have ENV50140:93, see paragraph 5 and 8 where 900MHz is discussed. Its gone from EN 61000-4-3:96. EN 61000-4-3:96+A1 adds bits about testing/protection against RF emissions from digital radio telephones throughout the document. In all cases, tests are conducted with an 80% modulated 1kHz sine wave (instead of pulse modulation at 200Hz). A1 was added to justify this.
