Germany 
The following markings are required: 
a) In case of intrinsically ionizing radiation safe 
cathode-ray tubes with accelerating voltages 
between 20 kV and 30 kV: 
- On the cathode-ray tube itself the wording: 
Eigensichere Kathodenstrahlröhre nach Anlage 
III Röntgen-verordnung 
- Inside the apparatus: 
the maximum allowed accelerating voltage in kV, 
and the maximum allowed beam current in mA. 
- On the outer of the apparatus: 
a notice in German language that produced X-
rays are sufficiently shielded by the intrinsically 
safe cathode-ray tube. 
b) In case of approval of the whole TV receiver 
with an accelerating voltage 
exceeding 20 kV: 
- On the outer of the apparatus: 
the licence number .../.../.../Rö, and the following 
text: 
Die in diesem Gerät entstehende 
Röntgenstrahlung ist ausreichend 
abgeschirmt. Beschleunigungsspannung: max: ... 
kV. 
- Supplied with the apparatus: 
a copy of the "Zulassungsschein", together with 
the notices required there. 
c) In case of TV receivers with accelerating 
voltages not exceeding 20 kV: 
Die in diesem Gerät entstehende 
Röntgenstrahlung ist ausreichend 
abgeschirmt. Beschleunigungsspannung: max: ... 
kV. 
Justification
German ministerial decree against ionizing 
radiation ( Röntgenverordnung), 
dated 1987-01-08. 
 
NOTE The German ministerial decree (Röntgenverordnung) 
is under revision.

5.1 
Italy 
The following requirements shall be fulfilled: 
- The power consumption in Watts (W) shall be 
indicated on TV receivers and in their instruction 
for use (Measurement according to EN 60555-2) 
NOTE EN 60555-2 has since been replaced by IEC 60107-
1:1997. 
- TV receivers shall be provided with an 
instruction for use, schematic diagrams 
and adjustments procedure in Italian language. 
- Marking for controls and terminals shall be in 
Italian language. Abbreviation and international 
symbols are allowed provided that they are 
explained in the instruction for use. 
- The ECC manufacturers are bound to issue a 
conformity declaration according to the above 
requirements in the instruction manual. The 
correct statement for conformity to be written in 
the instruction manual, shall be: 
Questo apparecchio è fabbricato nella CEE nel 
rispetto delle disposizioni del D.M. marzo 1992 
ed è in particolare conforme alle prescrizioni 
dell'art. 
1 dello stesso D.M. 
- The first importers of TV receivers 
manufactured outside EEC are bound to submit 
the TV receivers for previous conformity 
certification to the Italian Post Ministry (PP.TT). 
The TV receivers shall have on the backcover the 
certification number in the following form: 
D.M. 26/03/1992 xxxxx/xxxxx/S or T or pT 
S for stereo 
T for teletext 
pT for retrofitable teletext 
Justification: 
Ministerial Decree of 26 March 1992: National 
rules for television receivers 
trade. 
 
NOTE The ministerial decree above contains additional, but 
not safety relevant requirements.

Sweden 
The following is added: 
Switches containing mercury such as 
thermostats, relays and level controllers are not 
allowed. 
Justification: 
Ordinance (1990:944) on Prohibition in cnnection 
with Handling, Importation and Exportation of 
Chemical Products (Certain Cases) 
Only approved MOMS is 
provided.
