GB/T 18384 "Electrically propelled road vehicles - Safety specifications" is divided into three parts. - Part 1.On-board rechargeable energy storage system (REESS); - Part 2.Vehicle operational safety means and protection against failures; - Part 3.Protection of persons against electric shock. This Part is Part 3 of GB/T 18384. This Part was drafted according to the given rules of GB/T 1.1-2009. This Part replaces GB/T 18384.3-2001 "Electric vehicles - Safety specification - Part 3. Protection of persons against electric shock”. Compared with GB/T 18384.3-2001, except for structure difference in article and chapter and editorial modification, the main technical changes are as follows. - Modify the applicable scope of the standard (see Chapter 1; Chapter 1 in version 2001); - Delete the terms and definitions that have already been defined in the GB/T 19596 (see Chapter 3 in version 2001); - Add the definition of the rechargeable energy storage system (see 3.1); - Add the definition of “voltage Class A electric circuits” (see 3.2); - Add the definition of “voltage Class B electric circuits” (see 3.3); - Add the definition of “basic protection” (see 3.4); - Add the definition of “barriers” (see 3.5); - Add the definition of “enclosures” (see 3.6); - Modify the definition of “potential equalization” (see 3.7); - Add the definition of “balance of electric power system” (see 3.8); - Modify the voltage class division (see Chapter 4; Chapter 4 in version 2001). - Add the marking requirements (see Chapter 5); - Modify the protection in case of basic protection failure (see 6.3; 5.3 and Chapter 6 in version 2001); - Modify the requirements of isolation resistance (see 6.3.2; 6.2 in version 2001); - Add the capacitance coupling requirements (see 6.3.3); - Add power-off requirements (see 6.3.4); - Modify the barriers/enclosures requirements (see 6.6; 6.3 in version 2001); - Modify the measuring method of isolation resistance (see 7.2; 6.2.2 in version 2001). - Modify the test method of withstand voltage (see 7.3; 6.2.3 in version 2001); - Modify the test method of potential equalization (see 7.4; 6.4 in version 2001); - Modify the waterproof requirements (see Chapter 8; Chapter 7 in version 2001). This Part uses redrafting method to modify and adopt ISO 6469-3.2011 "Electrically propelled road vehicles - Safety specifications - Part 3.Protection of persons against electric shock”. The technical differences between this Part and ISO 6469-3.2011 and its reasons are as follows. - Delete some terms and definitions that have already been defined in the GB/T 19596, see Chapter 3. - Delete the explanation statement in Chapter 4 Environment and Operating Conditions in ISO 6469-1.2009.The related contents have been included in the experimental condition; the numbers of later sections and chapters are increased sequentially, see Chapter 4; - Add the waterproof requirements; - Delete the requirements about REESS crash test. There have been corresponding crash standards in China; the numbers of later sections and chapters are increased sequentially, see Chapter 7. This Part was proposed by the Ministry of Industry and Information Technology of People’s Republic of China. This Part shall be under jurisdiction of the National Vehicle Standardization Technical Committee (SAC/TC 114). Responsible drafting organizations of this Part.

This Part was first-time issued in July 2001; this is the first revision. Electrically propelled road vehicles – Safety specifications – Part 3.Protection of persons against electric shock1 Scope
This Part of GB/T 18384 specifies the requirements for the electric vehicle’s electric drive system and auxiliary system of conduction connection (if any), so as to protect the persons in car and out of the car from electric shock.2 Normative references
The following documents are essential to the application of this document. For dated references, only the dated version is applicable to this document. For undated references, its latest version (including all amendments) is applicable to this document. GB 2893 Safety colours (GB 2893-2008, ISO 3864-1.2002, MOD) GB 2894 Safety signs and guideline for the use3 Terms and definitions
For the purpose of this document, the following terms and definitions AND those defined in GB/T 19596 shall apply. Electric modules or circuits of which the maximum working voltage is less than or equal to 30 V a.c. (rms), or less than or equal to 60 V d.c.4 Voltage Classes
Based on the maximum working voltage U, the electric components or circuits shall be divided into the following classes, as shown in Table 1.5 Marking
If voltage class B’s live parts are exposed when barriers or enclosures is removed, the clear and visible symbol shall be on the barriers and enclosures. The outer layer of cable and wire-harness in Class B electric circuit shall be distinguished by orange, except for those inside the enclosures or behind the barriers.6 Method and requirement of electric shock protection for persons
It shall prevent persons to directly contact the live part of Class B electric circuit. Protection shall be achieved by the following two methods or one of them. If the minimum isolation resistance of above mentioned circuit is unable to meet requirements in operation conditions and in entire life cycle, it shall adopt one or more of the following measures to ensure safety.7 Test method of electric shock protection
Alternative preconditioning and conditioning parameters may be selected provided transition across the dew point occurs shortly after the beginning of the conditioning period. The isolation resistance shall be measured during the conditioning period at a rate from which the lowest value can be determined. The following test procedure combines the measurement of the isolation resistance of the live parts of the voltage class B balance of electric power systems against the vehicle electric chassis and against the live parts of the voltage class A balance of auxiliary electric systems.8 Waterproof
The test is to simulate the electric vehicle’s normal cleaning, not including washing with high-pressure water gun and special cleaning to vehicle bottom. The vehicle manufacturer shall specify special cleaning conditions in user manual in detail. This test is to simulate the case that when it suddenly rains heavily (for example. the thunderstorm), the openable parts leading to the passenger compartment, goods9 Owner's manual
Special attention to electric safety shall be given in the owner's manual.Annex A
(informative annex) Hose nozzle for test This Annex specifies structure and size of hose nozzle for IPX 5 test, see Figure A.1 (according to provisions in GB 4208). ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
