1. Access probes
Access probes to verify the protection of persons against access to live parts are given in Table 1.
2. Test conditions
The access probe is pushed against any openings of the enclosure with the force specified in Table 1. If it partly or fully penetrates, it is placed in every possible position, but in no case shall the stop face fully penetrate through the opening.
Internal barriers are considered part of the enclosure
A low-voltage supply (of not less than 40 V and not more than 50 V) in series with a suitable lamp should be connected, if necessary, between the probe and live parts inside the barrier or enclosure.
The signal-circuit method should also be applied to the moving live parts of high voltage equipment.
Internal moving parts may be operated slowly, where this is possible.
3. Acceptance conditions
The access probe shall not touch live parts.
If this requirement is verified by a signal circuit between the probe and live parts, the lamp shall not light.
In the case of the test for IPXXB, the jointed test finger may penetrate to its 80 mm length, but the stop face (diameter 50 mm x 20 mm) shall not pass through the opening. Starting from the straight position, both joints of the test finger shall be successively bent through an angle of up to 90 degrees with respect to the axis of the adjoining section of the finger and shall be placed in every possible position.

Annex 4A
Isolation resistance measurement method for vehicle based tests
1. General
The isolation resistance for each high voltage bus of the vehicle shall be measured or shall be determined by calculation using measurement values from each part or component unit of a high voltage bus (hereinafter referred to as the "divided measurement").
2. Measurement method
The isolation resistance measurement shall be conducted by selecting an appropriate measurement method from among those listed in paragraphs 2.1. through 2.2. of this annex, depending on the electrical charge of the live parts or the isolation resistance, etc.
The range of the electrical circuit to be measured shall be clarified in advance, using electrical circuit diagrams, etc.
Moreover, modification necessary for measuring the isolation resistance may be carried out, such as removal of the cover in order to reach the live parts, drawing of measurement lines, change in software, etc.
In cases where the measured values are not stable due to the operation of the on-board isolation resistance monitoring system, etc., necessary modification for conducting the measurement may be carried out, such as stopping of the operation of the device concerned or removing it. Furthermore, when the device is removed, it shall be proven, using drawings, etc., that it will not change the isolation resistance between the live parts and the electrical chassis.
Utmost care shall be exercised as to short circuit, electric shock, etc., for this confirmation might require direct operations of the high-voltage circuit.
2.1. Measurement method using voltage from off-vehicle sources
2.1.1. Measurement instrument
An isolation resistance test instrument capable of applying a DC voltage higher than the working voltage of the high voltage bus shall be used.
2.1.2. Measurement method
An insulator resistance test instrument shall be connected between the live parts and the electrical chassis. Then, the isolation resistance shall be measured by applying a DC voltage at least half of the working voltage of the high voltage bus.
If the system has several voltage ranges (e.g. because of boost converter) in galvanically connected circuit and some of the components cannot withstand the working voltage of the entire circuit, the isolation resistance between those components and the electrical chassis can be measured separately by applying at least half of their own working voltage with those component disconnected.
2.2. Measurement method using the vehicle’s own REESS as DC voltage source
2.2.1. Test vehicle conditions
The high voltage-bus shall be energized by the vehicle’s own REESS and/or energy conversion system and the voltage level of the REESS and/or energy conversion system throughout the test shall be at least the nominal operating voltage as specified by the vehicle manufacturer.
2.2.2. Measurement instrument
The voltmeter used in this test shall measure DC values and shall have an internal resistance of at least 10 MΩ.
2.2.3. Measurement method
2.2.3.1. First step
The voltage is measured as shown in Figure 1 and the high voltage bus voltage (Vb) is recorded. Vb shall be equal to or greater than the nominal operating voltage of the REESS and/or energy conversion system as specified by the vehicle manufacturer.
Figure 1
Measurement of Vb, V1, V2
Measure and record the voltage (V1) between the negative side of the high voltage bus and the electrical chassis (see Figure 1).
2.2.3.3. Third step
Measure and record the voltage (V2) between the positive side of the high voltage bus and the electrical chassis (see Figure 1).
2.2.3.4. Fourth step
If V1 is greater than or equal to V2, insert a standard known resistance (Ro) between the negative side of the high voltage bus and the electrical chassis. With Ro installed, measure the voltage (V1’) between the negative side of the high voltage bus and the electrical chassis (see Figure 2).
Calculate the electrical isolation (Ri) according to the following formula:
Ri = Ro*(Vb/V1’ – Vb/V1) or Ri = Ro*Vb*(1/V1’ – 1/V1)
Figure 2
Measurement of V1’
If V2 is greater than V1, insert a standard known resistance (Ro) between the positive side of the high voltage bus and the electrical chassis. With Ro installed, measure the voltage (V2’) between the positive side of the high voltage bus and the electrical chassis (see Figure 3). Calculate the electrical isolation (Ri) according to the formula shown. Divide this electrical isolation value (in Ω) by the nominal operating voltage of the high voltage bus (in volts).

3.3. The calibration curve shall not differ by more than two per cent from the nominal value of each calibration gas.
3.4. Using the coefficients of the polynomial derived from paragraph 3.2. above, a table of analyser readings against true concentrations shall be drawn by steps no greater than 1 per cent of full scale. This is to be carried out for each analyser range calibrated.

In the case of a REESS designed for a specific vehicle use, vehicle parts which affect the course of the fire in any way shall be taken into consideration.
3.2.2. Component based test
The tested-device shall be placed on a grating table positioned above the pan, in an orientation according to the manufacturer’s design intent.
The grating table shall be constructed by steel rods, diameter 6-10 mm, with 4-6 cm in between. If needed the steel rods could be supported by flat steel parts.
3.3. The flame to which the tested-device is exposed shall be obtained by burning commercial fuel for positive-ignition engines (hereafter called "fuel") in a pan. The quantity of fuel shall be sufficient to permit the flame, under free-burning conditions, to burn for the whole test procedure.
The fire shall cover the whole area of the pan during whole fire exposure. The pan dimensions shall be chosen so as to ensure that the sides of the tested-device are exposed to the flame. The pan shall therefore exceed the horizontal projection of the tested-device by at least 20 cm, but not more than 50 cm. The sidewalls of the pan shall not project more than 8 cm above the level of the fuel at the start of the test.
3.4. The pan filled with fuel shall be placed under the tested-device in such a way that the distance between the level of the fuel in the pan and the bottom of the tested-device corresponds to the design height of the tested-device above the road surface at the unladen mass if paragraph 3.2.1. above is applied or approximately 50 cm if paragraph 3.2.2. above is applied. Either the pan, or the testing fixture, or both, shall be freely movable.
3.5. During phase C of the test, the pan shall be covered by a screen. The screen shall be placed 3 cm +/- 1 cm above the fuel level measured prior to the ignition of the fuel. The screen shall be made of a refractory material, as prescribed in Annex 8E - Appendix 1. There shall be no gap between the bricks and they shall be supported over the fuel pan in such a manner that the holes in the bricks are not obstructed. The length and width of the frame shall be 2 cm to 4 cm smaller than the interior dimensions of the pan so that a gap of 1 cm to 2 cm exists between the frame and the wall of the pan to allow ventilation. Before the test the screen shall be at least at the ambient temperature. The firebricks may be wetted in order to guarantee repeatable test conditions.
3.6. If the tests are carried out in the open air, sufficient wind protection shall be provided and the wind velocity at pan level shall not exceed 2.5 km/h.
3.7. The test shall comprise of three phases B-D, if the fuel is at least at temperature of 20 °C. Otherwise the test shall comprise four phases
A–D.
3.7.1. Phase A: Pre-heating (Figure 1)
The fuel in the pan shall be ignited at a distance of at least 3 m from the tested-device. After 60 seconds pre-heating, the pan shall be placed under the tested-device. If the size of the pan is too large to be moved without risking liquid spills etc. then the tested-device and test rig can be moved over the pan instead.
Figure 1
Phase A: Pre-heating
3.7.2. Phase B: Direct exposure to flame (Figure 2)
The tested-device shall be exposed to the flame from the freely burning fuel for 70 seconds.
Figure 2
Phase B: Direct exposure to flame
3.7.3. Phase C: Indirect exposure to flame (Figure 3)
As soon as phase B has been completed, the screen shall be placed between the burning pan and the tested-device. The tested-device shall be exposed to this reduced flame for a further 60 seconds.
Instead of conducting phase C of the test, phase B may at the manufacturer’s discretion be continued for an additional 60 seconds.
However this shall only be permitted where it is demonstrable to the satisfaction of the Technical Service that it will not result in a reduction in the severity of the test.
Figure 3
Phase C: Indirect exposure to flame
3.7.4. Phase D: End of test (Figure 4)
The burning pan covered with the screen shall be moved back to the position described in phase A. No extinguishing of the tested-device shall be done. After removal of the pan the tested-device shall be observed until such time as the surface temperature of the tested-device has decreased to ambient temperature or has been decreasing for a minimum of 3 hours.

1. Purpose
The purpose of this test is to verify the performance of the overcharge protection.
2. Installations
This test shall be conducted, under standard operating conditions, either with the complete REESS (this maybe a complete vehicle) or with related REESS subsystem(s), including the cells and their electrical connections. If the manufacturer chooses to test with related subsystem(s), the manufacturer shall demonstrate that the test result can reasonably represent the performance of the complete REESS with respect to its safety performance under the same conditions.
The test may be performed with a modified tested-device as agreed by the manufacturer and the Technical Service. These modifications shall not influence the test results.
3. Procedures
3.1. General test conditions
The following requirements and conditions shall apply to the test:
(a) The test shall be conducted at an ambient temperature of 20 ± 10 °C or at higher temperature if requested by the manufacturer;
(b) At the beginning of the test, all protection devices which would affect the function of the tested-device and which are relevant to the outcome of the test shall be operational.
3.2. Charging
At the beginning all relevant main contactors for charging shall be closed.
The charge control limits of the test equipment shall be disabled.
The tested-device shall be charged with a charge current of at least 1/3C rate but not exceeding the maximum current within the normal operating range as specified by the manufacturer.
The charging shall be continued until the tested-device (automatically) interrupts or limits the charging. Where an automatic interrupt function fails to operate, or if there is no such function the charging shall be continued until the tested-device is charged to twice of its rated charge capacity.
3.3. Standard cycle and observation period
Directly after the termination of charging a standard cycle as described in Annex 8, Appendix 1 shall be conducted, if not inhibited by the tested-device.
The test shall end with an observation period of 1 h at the ambient temperature conditions of the test environment.
Annex 8H
Over-discharge protection
1. Purpose
The purpose of this test is to verify the performance of the over-discharge protection. This functionality, if implemented, shall interrupt or limit the discharge current to prevent the REESS from any severe events caused by a too low SOC as specified by the manufacturer.
2. Installations
This test shall be conducted, under standard operating conditions, either with the complete REESS (this maybe a complete vehicle) or with related REESS subsystem(s), including the cells and their electrical connections. If the manufacturer chooses to test with related subsystem(s), the manufacturer shall demonstrate that the test result can reasonably represent the performance of the complete REESS with respect to its safety performance under the same conditions.
The test may be performed with a modified tested-device as agreed by the manufacturer and the Technical Service. These modifications shall not influence the test results.
3. Procedures
3.1. General test conditions
The following requirements and condition shall apply to the test:
(a) The test shall be conducted at an ambient temperature of 20 ± 10 °C or at higher temperature if requested by the manufacturer;
(b) At the beginning of the test, all protection devices which would affect the function of the tested-device and which are relevant for the outcome of the test shall be operational.
3.2. Discharging
At the beginning of the test, all relevant main contactors shall be closed.
A discharge shall be performed with at least 1/3 C rate but shall not exceed the maximum current within the normal operating range as specified by the manufacturer.
The discharging shall be continued until the tested-device (automatically) interrupts or limits the discharging. Where an automatic interrupt function fails to operate, or if there is no such function then the discharging shall be continued until the tested-device is discharged to 25 per cent of its nominal voltage level.
3.3. Standard charge and observation period
Directly after termination of the discharging the tested-device shall be charged with a standard charge as specified in Annex 8, Appendix 1 if not inhibited by the tested-device.
The test shall end with an observation period of 1 h at the ambient temperature conditions of the test environment
Annex 8I
Over-temperature protection
1. Purpose
The purpose of this test is to verify the performance of the protection measures of the REESS against internal overheating during the operation, even under the failure of the cooling function if applicable. In the case that no specific protection measures are necessary to prevent the REESS from reaching an unsafe state due to internal over-temperature, this safe operation must be demonstrated.
2. Installations
2.1. The following test may be conducted with the complete REESS (maybe as a complete vehicle) or with related REESS subsystem(s), including the cells and their electrical connections. If the manufacturer chooses to test with related subsystem(s), the manufacturer shall demonstrate that the test result can reasonably represent the performance of the complete REESS with respect to its safety performance under the same conditions. The test may be performed with a modified tested-device as agreed by the manufacturer and the Technical Service. These modifications shall not influence the test results.
2.2. Where a REESS is fitted with a cooling function and where the REESS will remain functional without a cooling function system being operational, the cooling system shall be deactivated for the test.
2.3. The temperature of the tested-device shall be continuously measured inside the casing in the proximity of the cells during the test in order to monitor the changes of the temperature. The onboard sensor if existing may be used. The manufacturer and Technical Service shall agree on the location of the temperature sensor(s) used.
3. Procedures
3.1. At the beginning of the test, all protection devices which affect the function of the tested-device and are relevant to the outcome of the test shall be operational, except for any system deactivation implemented in accordance with paragraph 2.2. above.
3.2. During the test, the tested-device shall be continuously charged and discharged with a steady current that will increase the temperature of cells as rapidly as possible within the range of normal operation as defined by the manufacturer.
3.3. The tested-device shall be placed in a convective oven or climatic chamber. The temperature of the chamber or oven shall be gradually increased until it reaches the temperature determined in accordance with paragraph 3.3.1. or 3.3.2. below as applicable, and then maintained at a temperature that is equal to or higher than this, until the end of the test.
3.3.1. Where the REESS is equipped with protective measures against internal overheating, the temperature shall be increased to the temperature defined by the manufacturer as being the operational temperature threshold for such protective measures, to insure that the temperature of the tested-device will increase as specified in paragraph 3.2. above.
3.3.2. Where the REESS is not equipped with any specific measures against internal over-heating, the temperature shall be increased to the maximum operational temperature specified by the manufacturer.
3.4. The end of test: The test will end when one of the followings is observed:
(a) The tested-device inhibits and/or limits the charge and/or discharge to prevent the temperature increase;
(b) The temperature of the tested-device is stabilised, which means that the temperature varies by a gradient of less than 4 °C through 2 hours;
(c) Any failure of the acceptance criteria prescribed in paragraph 6.9.2.1. of the Regulation.
