6.1.2.1 

In Finland, Norway and Sweden, add the following text between the first and 
second paragraph of the compliance clause: 
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 2.10.11 with an electric strength  

 

test of 1,5 kV multiplied by 1,6 (the electric strength test of 2.10.10 shall be  

 

performed using 1,5 kV), and 

- 

is subject to ROUTINE 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. 
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 60950-1:2006, 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.

6.1.2.2 

In Finland, Norway and Sweden, the exclusions are applicable for 
PERMANENTLY CONNECTED EQUIPMENT, PLUGGABLE EQUIPMENT TYPE 
B and equipment intended to be used in a RESTRICTED ACCESS LOCATION 
where equipotential bonding has been applied, e.g. in a telecommunication centre, 
and which has provision for a permanently connected PROTECTIVE EARTHING 
CONDUCTOR and is provided with instructions for the installation of that conductor 
by a SERVICE PERSON.

7.2 

In Finland, Norway and Sweden, for requirements see 6.1.2.1 and 6.1.2.2 of this 
annex. 
The term TELECOMMUNICATION NETWORK in 6.1.2 being replaced by the term 
CABLE DISTRIBUTION SYSTEM.

7.3 

In Norway and Sweden, there are many buildings where the screen of the coaxial 
cable is normally not connected to the earth in the building installation.
