electrical/electronic disturbances from narrowband radiated electromagnetic
energy
The sensor shall be capable of withstanding a voltage of 50 Hz and an actual
sine wave of 500 V for a period of 1 min. The product after test shall comply
with the provisions of 4.2.
Note: For passive device sensors, it is recommended to measure the insulation
resistance.
4.6 Temperature resistance

When the sensor is subject to the low-temperature storage test at -40 °C and
restored at the test environment for 2 h, the performance shall be in accordance
with the provisions of 4.2.
4.6.2 High-temperature storage performance
When the sensor is subject to the high-temperature storage test at 85 °C and
restored at the test environment for 2 h, the performance shall be in accordance
with the provisions of 4.2.
