This part is the Part 3 of GB/T 18384.
This part was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 18384.3-2001 Electric Vehicles — Safety Specification — Part 3: Protection of Persons against Electric Hazards; except clause structure difference and editorial changes, the following technical deviations have been made with respect to the GB/T 18384.3-2001 (the previous edition):
— The application scope was modified (see Clause 1 of this standard and Edition 2001);

— The requirements of insulation resistance were modified (see 6.3.2 of this standard and 6.2 of Edition 2001);
— The requirements of capacity coupling were added (see 6.3.3);
— The requirements of power off were added (see 6.3.4);
— The requirements of barrier/enclosure were modified (see 6.6 of this standard and 6.3 of Edition 2001);
— The insulation resistance measurement method was modified (see 7.2 of this standard and 6.2.2 of Edition 2001);
— The method of withstand voltage test was modified (see 7.3 of this standard and 6.2.3 of Edition 2001);
— The method of potential equalization test was modified (see 7.4 of this standard and 6.4 of Edition 2001);
— The requirements of protection against water effects were modified (see Clause 8 of this standard and Clause 7 of Edition 2001).
This part has been redrafted and modified adoption of International Standard ISO 6469-3:2011 Electrically Propelled Road Vehicles — Safety Specifications — Part 3: Protection of Persons against Electric Shock.
The main technical differences between this part and ISO 6469-3: 2011 and their reasons are as follows:
— Some terminologies and definitions were deleted because they have been defined in GB/T 19596, see Clause 3;
— The description of environmental and operating conditions in Clause 4 of ISO 6469-1:2009 was deleted because the relevant contents are contained in the experimental conditions, and the subsequent clauses and sections were renumbered in sequence, see Clause 4;
— The requirements of protection against water effects were added;
— The requirements of REESS impact test were deleted because there are corresponding impact standards in China, and the subsequent clauses and sections were renumbered in sequence, see Clause 7.
This part was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This part is under the jurisdiction of the National Technical Committee on Automobiles of Standardization Administration of China (SAC/TC 114).
This part was issued in July, 2001 as first edition, and this is the first revision.
Electrically Propelled Road Vehicles — Safety Specifications — Part 3: Protection of Persons against Electric Shock
1 Scope
This part of GB/T 18384 specifies requirements for the electric propulsion systems and conductively connected auxiliary electric systems, if any, of electrically propelled road vehicles for the protection of persons inside and outside the vehicle against electric shock.
This part is applicable to the electrically propelled road vehicles whose maximum working voltage of on-board propulsion system is voltage class B. Electric motorcycles and electric mopeds may also refer to the provisions of this standard.
This part is not applicable to vehicles not primarily intended as road vehicles, such as material handling trucks and forklifts.
This part does not provide comprehensive safety information for manufacturing, maintenance and repair personnel of electrically propelled road vehicles.
