According to EMC Standard : EN 61000-3-3
7.2. Test Setup
7.3. Limit
The following limits apply:
the value of P
st
shall not be greater than 1.0;
the value of P
lt
shall not be greater than 0.65;
the value of d(t) during a voltage change shall not exceed 3.3 for more than 500
ms;
the relative steady-state voltage change, d
c
, shall not exceed 3.3 ;
the maximum relative voltage change, d
max
, shall not exceed;
a) 4 without additional conditions;
b) 6 for equipment which is:
switched manually, or
switched automatically more frequently than twice per day, and also has either a
delayed restart (the delay being not less than a few tens of seconds), or manual restart,
after a power supply interruption.
NOTE The cycling frequency will be further limited by the P
st
and P
1t
limit.
For example: a d
max
of 6producing a rectangular voltage change characteristic twice per
hour will give a P
1t
of about 0.65.
