In Finland, Norway and Sweden TOUCH
CURRENT measurement results exceeding 3,5
mA r.m.s. are permitted only for the following
equipment:

STATIONARY PLUGGABLE EQUIPMENT
TYPE A that is intended to be used in a
RESTRICTED ACCESS LOCATION where
equipotential bonding has been applied, for
example, in a telecommunication centre; and

has provision for a permanently connected
PROTECTIVE EARTHING CONDUCTOR; and

is provided with instructions for the installation of
that conductor by a SERVICE PERSON;

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.
