IEC 62151 clause 4.1.1:  
Add after the first paragraph: 

 

NOTE-
 In Finland, Norway and Sweden, class I equipment  
which is intended for connection to the building  
installation via a non-industrial plug or a non-industrial 
appliance coupler or both and in addition is intended  
for connection to other equipment or a network shall, 
if safety relies on connection to protective earth or if  
surge suppressors are connected between the  
network terminals and ACCESSIBLE parts, have  
a marking stating that the equipment must be  
connected to an earthed mains socket-outlet. 

 

The marking text in the applicable countries shall 
be as follow: 

 

In Finland;  
”Laite on liitettävä suojamaadoituskoskettimilla 
va rustettuumpistorasiaan” 

 

In Norway; ”Apparatet mǻ tikoples jordet stikkontakt” 

 

In Sweden; ”Apparaten skall anslutas till jordat uttag”

The input tests were conducted at 1 kHz sign wave input signal with 8 ohm loads connected conditions for  
F, C and S channels, and than replaced the input signal to pink noise for heating and fault condition tests 

The values followed #) in table above are measured “A” or “W” value, when replaced the input signal from 
1 kHz sign wave to pink noise.
