To the 2 questions:
Question1: Where can I find the "number of pulses per minute" defined for
industrial equipment when applying IEC 1000-4-5 or EN 61000-4-5 ?
Or does anyone know this number?
Answer: When testing according to IEC 1000-4-5/1995 the repetition rate
shall be maximum 1/min (§8.2); whereas the generator used shall be able to
supply a repetition rate of "at least 1 per min" (§6.1.1 and §6.2.1).
Question2: Does anyone have a 1997 edition of EN 500082-2 ? If you do,
where were you able to purchase it??
Answer: There is no approved 1997 edition of EN 50082-2. But in 1997 there
came a new revised edition of EN 50082-1 - maybe that could be the
reason for a little confusion.
Hope this helps
