current over 10A and up to and including 13A  

Class III equipment. 

3.3.4 C  

In table 3D, delete the fourth line - conductor sizes 
for 10 to 13 A, and replace with the following:  
"Over 10 up to and including 16:    1,5 to 2,5     
1,5 to 4" 
Delete the fifth line - conductor sizes for  
13 to 16A  

Class III equipment.

(GB) 

The range of conductor sizes of flexible 

cords to be accepted by terminals for equipment 
with a rated current of over 10A and up to and 
including 13A is:  
1,25mm² to 1,5mm² nominal cross- sectional area  

Class III equipment. 

4.3.6 S 

(GB) 

The torque test is performed using a socket 

outlet complying with BS 1363 and the plug part of 
direct plug -in equipment shall be assessed to BS 
1363: Part 1, 12.1, 12.2, 12.3, 12.9, 12.11,  12.12, 
12.16 and 12.17, except that the test of 12.17 is 
performed at not less than 125

°

C  

Not direct plug-in equipment. 

4.3.6 S 

(IE) 

Direct plug -in equipment is known as plug 

similar devices. Such devices shall comply with 
Statutory Instrument 526:1997 – National 
Standards Authority of Ireland (Section 28) 
(Electrical plugs, plug similar devices and sockets 
for domestic use) Regulations, 1997  

Not direct plug-in equipment. 

4.3.13 C  

Replace the second compliance paragraph by: 
For equipment using LEDs or lasers, compliance 
is checked according to EN 60825-1 

NOTE 1 – If equipment falling within the scope of 
EN 60950 is inherently a class 1 laser product, i.e. 
it contains no embedded laser or LED of a higher 
class number, then a laser warning label or other 
laser warning statement is not required (se e 1.1 of 
EN 60825 -1) 
Renumber the NOTE below the third compliance 
paragraph as NOTE 2  

LEDs are diffused type.

6.1.2.1 S 

(NO, SE)

 Add the following text between the first and 

second paragraph: 

If this insulation is solid, including insulation forming a 
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 0.4mm, which shall pass the electric  strength test 
below. 

If this insulation forms a 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 1.5kV multiplied by 1.6 (the 
electric strength test of 2.10.7 shall be performed using 
1.5kV); and 

- is subjected to routine testing for electric strength 
during manufacturing, using a test voltage of 1.5kV. 

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

 

 

No TNV circuits. 

6.1.2.2 S  

(FI, NO, SE)

 The exclusions are applicable for 

Permanently Connected Equipment and 
Pluggable Equipment Type B only  

No TNV circuits. 

G.2 S 

(NO)

 Due to the IT power distribution system used 

(see Annex V, figure V.7), the a.c. mains supply 
voltage is considered to be equal to the line -to-line 
voltage, and will remain at 230V in case of a 
single earth fault 

Considered. 

Annex H C 

Replace the last paragraph of this annex by: At 
any p oint 10cm from the surface of the operator 
access area, the dose rate shall not exceed 
1

µ

Sv/h (0.1 mR/h) (see note). Account is taken of 

the background level. 

The unit does not emit X-ray radiation. 

Annex H C 

Replace the note as follows: NOTE – These 
values appear in Directive 96/29/Euratom 

The unit does not emit X-ray radiation.

Annex H A 

(DE) 

(Regulation on protection against hazards by X-

ray, of 8

th

 January 1987, Article 5 [Operation of 

X-ray emission source], clauses 1 to 4) 

a)  A licence is required by those who operate an 

X-ray emission source. 

b)  A licence in accordance with clause 1 is not 

required by those who operate an X-ray 
emission source on which the electron 
acceleration voltage does not exceed 20kV if 

1)  the local dose rate at a dista nce of 0,1m from 

the surface does not exceed 1µSv / h and  

2)  it is adequately indicated on the X-ray 

emission source that 
i) X-rays are generated and  
ii) the electron acceleration voltage must not 
exceed the maximum value stipulated by the 
manufacturer or importer. 

c)  A licence in accordance with Clause 1 is also            

not required by persons who operate an X -ray 
emission source on which the electron 
acceleration voltage exceeds 20kV if 

1)  the X -ray emission source has been granted 

a type approval and 

2)   it is adequately indicated on the X-ray 

emission source that 
i) X-rays are generated 
ii) the device stipulated by the manufacturer 
or importer guarantees that the maximum 
permissible local dose rate in accordance 
with the type approval is not exceeded and  
iii) the electron acceleration voltage must not 
exceed the maximum value stipulated by the 
manufacturer or importer. 

d)  Furthermore, a licence in accordance with 

Clause 1 is also not required by persons who 
operate X -ray emission sources on which the 
electron acceleration voltage does not exceed 
30kV if  

1)  the X -rays are generated only by intrinsically 

safe CRTs complying with Enclosure III, No. 
6, 

2)  the values stipulated in accordance with 

Enclosure III, No. 6.2 are limited by technical 
measures and specified in the device and  

3)  it is adequately indicated on the X-ray 

emission source that the X -rays generated 
are adequately screened by the intrinsically 
safe CRT.  

The unit does not emit X-ray radiation.
