7 General test requirements
7.1 All tests in this standard are type tests.
7.2 Unless otherwise specified, type tests shall be carried out on a single specimen as delivered and configured in accordance with the manufacturer’s instructions.
7.3 The tests in 1 1 .3 may be conducted on separate samples at the discretion of the manufacturer. Unless otherwise specified, all other tests shall be carried out in the order of the clauses and subclauses in this part.
7.4 The tests shall be carried out with the specimen, or any movable part of it, placed in the most unfavourable position which may occur in normal use.
7.5 Unless otherwise specified, the tests shall be carried out in a draught-free location and at an ambient temperature of 20 °C ± 5 °C.
7.6 The characteristics of the test voltages in 1 0.1 shall comply with IEC 61 1 80-1 .
8 Functional and constructional requirements
8.1 Control functions For mode 3 charging, the a.c. electric vehicle charging station provides part of the control functions listed in 6.4 of part 1 of this standard.
8.2 Emergency service If required by national rules, an emergency disconnection device shall be installed to isolate the a.c. supply network (mains) from the a.c. electric vehicle charging station in case of risk of electric shock, fire or explosion. The disconnection device shall be provided with a means to prevent accidental operation.
8.3 Permissible surface temperature The maximum permissible surface temperature of parts of the a.c. electric vehicle charging station which are hand grasped, at the maximum rated current and at an ambient temperature of 40 °C, shall be
– 50 °C for metal parts;
– 60 °C for non-metallic parts.
For parts which may be touched but not grasped, maximum permissible surface temperature under the same conditions shall be
– 60 °C for metal parts;
– 85 °C for non-metallic parts.
NOTE National codes may allow other temperatures.
8.4 Charging station protection degree (IP)
The a.c. electric vehicle charging station, when energized or not, and with the socket-outlet access trap door, if any, closed, shall provide a minimum degree of protection of IP44.
Compliance is checked by test in accordance with IEC 60529.
8.5 Storage means for the cable assembly
For case C connections, a storage means shall be provided for the cable assembly and vehicle connector when not in use. The a.c. electric vehicle charging station should be provided with a means to indicate whether or not the cable assembly/vehicle connector has been stored as intended after disconnection from the vehicle.
