Power rating marking:  
Item 1.7.1 of IEC 60950 does not specify 
concrete figures of markings for supply voltage 
and frequency, instead, descriprions are give 
by examples. But the examples do not include 
Chinas`s mains voltage. 
GB4943-2001 stiplulates that: 
- A single rated voltage shall be expressed as 
220V 
- When a rated volrage range is given, the 
range shall cover 220V 
- When a variety of rated voltages or rated 
voltage ranges are given, one of them shall be 
220V, and shall be set as 220V when 
dispatched from the factory 
- Rated frequency or rated frequency range 
shall be 50Hz or include 50Hz 
- If a unit is not provided with a means of direct 
connection to the a.c. mains supply, it need not 
be marked with any electrical rating

Add the following terms. 

Equipment, Class 0I  

1.2.4.101 

Material, VTM  

 

1.2.12.101 

Considered. 

— 

 

CLASS 0I EQUIPMENT: Equipment where protection 
against electric shock is achieved by: 

a) using BASIC INSULATION, and 

b) providing a means of connecting to the protective 
earthing conductor in the building wiring those 
conductive parts that are otherwise capable of 
assuming HAZARDOUS VOLTAGES if the BASIC 
INSULATION fails, and 

c) using a supply cord without earthing conductor and 
a plug without earthing wire although the equipment 
has externally an earth terminal or a lead wire for 
earthing. 

Equipment provided with a cord set having a two-pin 
type plug with a lead wire for earthing is also regarded 
as Class 0I. 

NOTE – Class 0I equipment may have a part 
constructed with Double Insulation or Reinforced 
Insulation as well as an operating part as SELV circuit.

Class III equipment. 

N/A 

 

FLAMMABILITY CLASSIFICATION OF MATERIALS: 
The recognition of the burning behaviour of materials 
and their ability to extinguish if ignited. Materials are 
classified as in 1.2.12.2 to 1.2.12.9, and 1.2.12.101 
when tested in accordance with annex A. 

NOTE 1 - When applying the requirements in this 
standard, HF-1 CLASS FOAMED MATERIALS are 
regarded as better than those of CLASS HF-2, and 
HF-2 better than HBF. 

NOTE 2 - Similarly, other MATERIALS, including rigid 
(engineering structural) foam of CLASSES 5V or V-0 
are regarded as better than those of CLASS V-1, V-1 
better than V-2, and V-2 better than HB. 

NOTE 3 - Similarly, for thin MATERIALS, VTM-0 Class 
materials are regarded as better than those of VTM-1 
Class, and VTM-1 better than VTM-2.

VTM CLASS MATERIAL: Thin MATERIALS fulfil the 
specified conditions during the test of clause A.101 
applied for materials that the test and evaluation of 
clauses A.6 to A.10 is difficult to enforce. Materials are 
classified to three classifications as VTM-0, VTM-1 and 
VTM-2 according to the conditions after the removal of 
the test flame.

1.7.101 

 

Marking for CLASS 0I EQUIPMENT 

For CLASS 0I EQUIPMENT, the following instruction 
shall be indicated on the visible place of the mains plug 
or the main body: 

“Provide an earthing connection” 

Moreover, for CLASS 0I EQUIPMENT, the following 
instruction shall be indicated on the visible place of the 
main body or written in the operating instructions: 

“Provide an earthing connection before the mains plug 
is connected to the mains. And, when disconnecting 
the earthing connection, be sure to disconnect after 
pulling out the mains plug from the mains.” 

Class lII equipment.
