FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation of national standards 
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are 
described in the ISO/IEC Directives, Part  1. In particular, the different approval criteria needed for the 
different types of ISO documents should be noted. This document was drafted in accordance with the 
editorial rules of the ISO/IEC Directives, Part  2 (see www.iso.org/directives ).
Attention is drawn to the possibility that some of the elements of this document may be the subject of 
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).
Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and 
expressions related to conformity assessment, as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html .
This document was prepared by Technical Committee ISO/TC  22 , Road vehicles , Subcommittee SC  38 , 
Motorcycles and mopeds .
This first edition of ISO 13063-3, together with ISO 13063-1 and ISO 13063-2, cancels and replaces ISO 13063:2012, which has been technically revised. 
The main changes are as follows:
— extension of protection against electric shock to all electric safety requirements;
— alignment of structure and requirements as possible with ISO 6469-3:2018;
— splitting the document into three  do cuments which consist of the following parts, under the general 
title Electrically propelled mopeds and motorcycles — Safety specifications:
— Part  1: On-board rechargeable energy storage system (RESS) ;
— Part  2: Vehicle operational safety ;
— Part  3: Electrical safety ;
— addition of specific requirements for capacitive discharge;
— new test specification for the isolation resistance monitoring system;
— new requirements and test for touch current; and
— the requirements for conductive connection to an external electric power supply can be covered by 
ISO 18 246.
A list of all parts in the ISO  13 063 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A 
complete listing of these bodies can be found at www.iso.org/members.html .

Part  3: 
Electrical safety
1 Scope
This document specifies electric safety requirements for protection against electric shock and thermal 
incidents of electric propulsion systems and conductively connected auxiliary electric systems of-electrically propelled mopeds and motorcycles when used in normal conditions. It is applicable to a 
maximum working voltage of the on-board electrical circuit up to 1  00 0 V a lternating current (a.c.) or 
1 500  V direct current (d.c.). This document does not provide comprehensive safety information for 
manufacturing, maintenance and repair personnel.
NOTE  Re quirements for conductive connections of electrically propelled mopeds and motorcycles to an 
external electric power supply are described in ISO 18246.

voltage ≤60  V d .c., which shall be passed through the equipotential bonding path between any two 
exposed conductive parts of voltage class B equipment for at least 5  s. This path shall be isolated from 
other unintended potential paths for measurement. These equipotential bonding paths shall include voltage class B component housings, connections to electric chassis and the vehicle electric chassis or protective barriers and protective enclosures.
A lower test current and/or a shorter test time may be used, provided the accuracy of the equipotential 
bonding resistance test results remains on a sufficiently accurate level.
The voltage drops between any two exposed conductive parts in a distance of 2,5  m w hich can be 
simultaneously touched by a person shall be measured. The resistance shall be calculated based on the applied current and this voltage drop.

of at least 8  h at (5 ± 2) °C , followed by a conditioning period of 8  h at a temperature of (23  ± 5) °C , a 
humidity of (90  + 10/-5)  %, and an atmospheric pressure of between 86  kPa and 106  kPa.
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.
11.3.2  Isolation resistanc e measurements of the balance of electric circuits
The test voltage shall be a DC voltage of at least the maximum working voltage of the voltage class 
B electric circuit or 500  V whichever is higher and be applied for a time long enough to obtain 
stable  r eading.
If the voltage class B electric circuit has several voltage ranges (e.g. because of boost converter) in conductively connected sections of the circuit and some of the components cannot withstand the maximum working voltage of the entire circuit, the isolation resistances of sections of the circuit can be measured separately by applying their own maximum working voltages after those sections of the circuit are disconnected.
The following test procedure combines the measurement of the isolation resistance of the live parts of 
the voltage class B balance of electric circuits against the vehicle electric chassis and against the live parts of the voltage class A balance of auxiliary electric circuits, if they are conductively connected to the electric chassis.
— RESS shall be disconnected at their terminals from the electric circuit.

11.3.3.2.3  Prepar ation for fuel cell stack
For the measurement of the isolation resistance of a fuel cell stack, the entire mechanical structure of the fuel cell system (including the cooling system with its cooling medium) shall be considered. Prior to the measurement, stop power generation after operation at maximum output according to the manufacturer’s specification. All cables shall be disconnected from the fuel-cell stack power terminals, and all other cables from other electric terminals of the fuel-cell stack. All cooling pipes, fuel pipes, and air pipes shall remain connected.
11.3.3.3  Proc edure
11.3.3.3.1  General
If switches for the electric power source current are integrated in the electric power source, they shall be closed during the measurement, unless they do not affect the test result.
The procedure for each measurement is the following [see 
Formula  ( 1)  and Figure  3 a)]:
Measure the voltage UEPS between the negative and the positive terminal of the electric power source. 
(EPS).
Measure the voltages between each terminal of the electric power source and the vehicle electric 
chassis, and name the higher one U1, the lower one U′1 and the two corresponding isolation resistances 
Ri1 and Ri2 = Ri.
NOTE  1 Ri2 is the lower isolation resistance and is therefore, the isolation resistance Ri to be determined.
— Add a known measuring resistance R0 parallel to Ri1 and measure the voltage U2.
— During the measurements, the test voltage shall be stable.
NOTE  2 Th eoretically, the value of R0 has no influence on the calculated isolation resistance. However, R0 it 
is possible to be selected such that sufficient accuracy is achieved for the measured voltages on the calculated isolation resistances. R
0 (Ω) can be the value of the minimum required isolation resistance (in Ω/V) multiplied by 
the maximum working voltage of the electric power source or voltage class B electric circuit which includes the 
electric power source  ± 20 %. R0 is not required to be precisely this value since the formulae are valid for any R0; 
however, a R0 value in this range provides an appropriate voltage range for the voltage measurements.
— Calculate the isolation resistance Ri, using R0 and the three voltages U1, U’1, and U2 with Formula  (1):
Ri = R0*UEPS*(1/ U2 – 1/ U1) ( 1)
a)   Measurement of U1 and U '1 b)   Addition of R0 and measurement of U2
