3 Terms and definitions
This standard uses the following terms and definitions.
3.1
Rotational speed sensor
A sensor, which measures the rotational speed of automobile engines,
gearboxes, wheels, etc. AND converts them into electrical signals. Usually it
includes crankshaft speed sensor, wheel speed sensor, gearbox speed
sensor, turbine speed sensor.
3.2
Crankshaft speed sensor
A sensor, which is installed on the engine, to detect the speed and position
of the crankshaft AND output electrical signals.
4 Requirements
4.1 General requirements
4.1.1 The sensor shall meet the requirements of this standard. IT shall be
manufactured in accordance with the drawings and design documents, which
are approved by the prescribed procedures.
4.2 Basic performance parameters
4.5 Temperature resistance
4.5.1 Resistance to low temperature storage
The sensor has undergone a storage test, at a low temperature of -40 °C, for a
duration of 24 hours; after 2 hours of recovery at room temperature, its
performance shall meet the requirements of 4.2.
4.5.4 Resistance to working at low temperature
When the sensor is subjected to the test of resistance to working at low
temperature at -40 °C, the performance shall meet the requirements of 4.2.
4.5.5 Resistance to working at high temperature
When the sensor is subjected to the test of resistance to working at high
temperature, as shown in Table 2, the performance shall meet the requirements
of 4.2.
4.7 Vibration resistance
The sensor shall be subjected to a vibration resistance test. After the test, the
appearance shall not be damaged; the performance shall meet the
requirements of 4.2.
4.8 Protection performance
The degree of protection of the sensor (except the connector) shall meet the
requirements of Table 3.
4.12 Durability
After the durability test of Table 5, the sensor for commercial vehicles shall meet
the requirements of 4.2.After the durability test in Table 6, the sensors for
passenger vehicles shall meet the requirements of 4.2.
5.6.4 Test of resistance to working at low temperature
It is carried out according to the provisions of 5.1.1.2.2 in GB/T 28046.4-2011.
The working mode 3.2 is changed to 3.1.
5.7 Test of resistance to cyclic damp heat
It is carried out according to 5.6.2.3 of GB/T 28046.4-2011.Perform 10 cycles
of combined temperature/humidity cycle test, in the range of -10 °C ~ 65 °C.
The working mode 3.2 is changed to 3.1 OR as negotiated with the customer.
5.11 Test of resistance to free fall
It is carried out according to the provisions of 4.3 in GB/T 28046.3-2011.
5.12 Chemical resistance test
It is carried out according to the provisions of GB/T 28046.5.
5.13 Durability test
Divide the samples into two groups, to carry out the following tests, respectively
(Hall/magneto-resistive sensors need to be tested in a charged state).
6 Inspection rules
6.1 Qualification documents and marking
The sensor can only leave the factory, after passing the inspection, AND
accompanied by a product quality certificate and marking.
6.3 Type inspection
6.3.1 Several situations for type inspection
In one of the following situations, the sensor shall be subject to type inspection.
6.3.2 Sampling and grouping
The samples for type inspection shall be taken from the same batch of samples,
that have passed the exit-factory inspection; the quantity shall not be less than
12.First perform reinspection, according to the exit-factory inspection items.
After passing the reinspection, divide the samples into 4 groups. Carry out the
test in the following grouping and item order.
6.3.3 Qualification judgment
The type inspection items of the sensor shall all meet the specified
requirements. If there is one unqualified item, it may re-take double quantity of
samples, to carry out reinspection of this unqualified item.
7 Marking, packaging, storage and custody
The marking, packaging, storage, custody of the sensor should be implemented
in accordance with the provisions of Chapter 6 of QC/T 413-2002.
