Add the following note: 

NOTE Attention is drawn to 1999/519/EC: 
Council Recommendation on the limitation of 
exposure of the general public to electromagnetic 
fields 0 Hz to 300 GHz. Standards taking into 
account this recommendation are currently under 
development.

6.1.2.1 

S (FI, NO): Add the following text between the 
first and second paragraph: 

If this insulation is solid, including insulation 
forming part of a component, it shall at least 
consist of either 

- two layers of thin sheet material, each of which 
shall pass the electric strength test below, or 

- one layer having a distance through insulation 
of at least 0,4 mm, which shall pass the electric 
strength test below. 

If this insulation forms part of a semiconductor 
component (e.g. an optocoupler), there is no 
distance through insulation requirement for the 
insulation consisting of an insulating compound 
completely filling the casing, so that 

CLEARANCES 

AND CREEPAGE DISTANCES

 do not exist, if the 

component passes the electric strength test in 
accordance with the compliance clause below 
and in addition 

- passes the tests and inspection criteria of 
2.10.8 with an electric strength test of 1,5 kV 
multiplied by 1,6 (the electric strength test of 
2.10.7 shall be performed using 1,5 kV), and 

- is subject to 

ROUTINGE TESTING

 for electric 

strength during manufacturing, using a test 
voltage of 1,5 kV. 

It is permitted to bridge this insulation with a 
capacitor complying with EN 132400:1994, 
subclass Y2.

(cont.) 

A capacitor classified Y3 according to 
EN 132400:1994, may bridge this insulation 
under the following conditions: 

- the insulation requirements are satisfied by 
having a capacitor classified Y3 as defined by 
EN 132400, which in addition to the Y3 testing, is 
tested with an impulse test of 2,5 kV defined in 
EN 60950-1:2001, 6.2.2.1; 

- the additional testing shall be performed on all 
the test specimens as described in EN 132400; 

- the impulse test of 2,5 kV is to be performed 
before the endurance test in EN 132400, in the 
sequence of tests as described in EN 132400.

shall pass the electric strength test below, or
