3 Definitions
This Standard adopts the following definitions.
3.1 Normally open contact
The contact that is in the disconnecting state, when the relay coil is not energized.
3.2 Normally closed contact
stipulate din Table 1 of QC/T 413; and perform low-temperature test for 8h as per the
selected lower limit storing temperature; when restoring to the room temperature, the
relay’s operating voltage, release voltage and contact voltage drop shall meet the
requirements of 4.6.1 and 4.6.2.
4.8.2 High-temperature resisting property
The relay can work as per the requirements in the upper limit working temperature
stipulate din Table 1 of QC/T 413; and perform high-temperature test for 8h as per the
selected upper limit storing temperature; when restoring to the room temperature, the
relay’s operating voltage, release voltage and contact voltage drop shall meet the
requirements of 4.6.1 and 4.6.2.
4.8.3 Temperature-change resisting property
Perform the temperature-change resisting property test as per the requirements of
3.10.3 of QC/T 413; after the completion of test and the temperature restoring to the
room temperature, the relay’s operating voltage, release voltage and contact voltage
drop shall meet the requirements of 4.6.1 and 4.6.2.
4.9 Product temperature-and-humidity-change resisting property
Perform the temperature-and-humidity-change resisting property test as per the
requirements of 3.11 of QC/T 413; after the completion of test and temperature
restoring to the room temperature, the relay’s contact voltage drop shall meet the
requirements of 4.6.2.
4.10 Vibration property
Under non-working conditions, the installation position shall be “other positions”
according to Table 3 in 3.12 of QC/T 413, the relay shall withstand sweep vibration test
from three directions, namely, X, Y, Z; after the completion of test, relay shall meet the
requirements of 4.6.1 and 4.6.2.
