    9.6.2 Specification of the foreign objects

    The following foreign objects are used:

    – a steel disc, see Figure 47;

    – an aluminium ring, see Figure 48; and

    – an aluminium foil, see Figure 49.


    9.6.3 Test method and compliance criteria

    The wireless power transmitter is placed in a room under the temperature conditions as

    specified in 9.3.2.

    The test is performed once with each of the foreign objects specified in 9.6.2 placed in direct

    contact with the transmitter. Each test has four cycles:

    – one without a receiver present and with the foreign object in direct contact with the

    transmitter; and

    – one with a receiver placed in direct contact with the foreign object; and

    – one with a receiver placed at a distance of 2 mm from the foreign object; and

    – one with a receiver placed at a distance of 5 mm from the foreign object.

    The transmitter is operated to transmit its maximum power.


    NOTE The test is not meant to test the temperature of the receiver, therefore any compatible receiver that can

    draw the maximum power from the wireless power transmitter can be used and the temperature of the receiver

    does not have to be monitored.

    During each cycle, the foreign object can be moved on the transmitter in order to find the

    location where the highest temperature occurs.

    During the tests, the temperature of the foreign object shall not exceed 70 °C.
