3 Terms and definitions
For the purpose of this Standard, the following terms and definitions shall apply. 3.1
Accessible part
The places, after the product is installed properly, where are accessible by using articulated test-finger (see Annex A).
3.2
Basic insulation
The insulation added by the dangerous charged components to provide basic protection against electric shock.
[See 2.6.3 of GB 8898-2001]
3.3
Supplementary insulation
The independent insulation that is used except the basic insulation, so as to provide protection against electric shock in the event of the failure of the basic insulation. [See 2.6.5 of GB 8898-2001]
3.4
Reinforced insulation
The single insulation that is added for dangerous charged components; the anti-electric shock grade is equivalent to double insulation.
[See 2.6.6 of GB 8898-2001]
3.5
Double insulation
Insulation that has simultaneously both the basic insulation and supplementary insulation. [See 2.6.4 of GB 8898-2001]

f) Secondary winding transformer is short circuit; short circuit of primary winding and secondary winding, short circuit of each winding with core and shield if there exists any core and shield;
g) The two poles of the capacitor are shorted; if there is enclosure, each pole is shorted to the metal enclosure;
h) In above test, if there is fault display, the test is 2min; if there is no fault display, the test is 4h; during the test, it shall not damage the equipment or cause a fire or electric shock.
Note. If fuse is disconnected or can not operate properly, then it is deemed as fault display.
5 Technical requirements and test methods
5.1 Equipment safety classification
According to different anti-electric shock protective measures provided by the equipment, the equipment can be divided into three classes.
Class I equipment. anti-electric shock does not only rely on basic insulation but also take additional safety measure design; when the basic insulation fails, there are measures to make protection (earthing) conductor of fixed-lines in
facilities connect with the accessible conductive components, so that the accessible conductive components will not produce dangerous charged
equipment.
requirements of transportation on the structure.
5.3 Marking
5.3.1 Contents of the marking
The equipment shall be marked with the following contents at least.
a) Name or registered trademark of the manufacturer;
