3 Test classification and items
3.1 Test items
The tests for the on-line monitoring device are divided into type test, exit-factory
test, commissioning test and field test. The test items are shown in Table 1.

2 Basic function testing ??? ??? ??? ???
3 Measurement error test ??? ??? ??? ???
4 Insulation resistance test ??? ??? ??? *
5 Dielectric strength test ??? ??? * *
3.4 Commissioning test
The commissioning test is carried out by the operating organization, after the
device is installed and before it is officially put into operation. The device can
only be operated after passing the test.
3.5 Field test
The field test is carried out by a field operating organization or a qualified testing
institution to the performance of the devices to be tested on site. Field tests are
generally divided into two cases.
a) regular routine verification, with a cycle of 1 to 2 years; and
b) if necessary.
4 Test methods and requirements
4.1 Test conditions
The requirements for the test conditions are as follows.
a) laboratory ambient temperature. +15??C ~ +35??C (outdoor tests are not
required);
b) relative humidity. 25% ~ 75%;
c) atmospheric pressure. 86kPa ~ 106kPa.
For large-size equipment, or the equipment cannot be tested under the above
conditions for some reason, the actual weather conditions shall be recorded in
the inspection report. When relevant standards require strict control of the
environmental conditions, such requirement shall be otherwise specified in this
Standard.
4.2 Structure and appearance inspection
The structure and appearance shall conform to the following requirements.
a) the device chassis shall take necessary measures against electromagnetic
interference, and the exposed conductive part of the chassis shall be
electrically connected together with reliable grounding;
b) the chassis shall meet the requirements for ventilation and heat dissipation
of the heating elements;
c) the chassis modules shall be plugged in a flexible way, with reliable contact
and good interchangeability; and
d) appearance coating and plating shall be solid, uniform and smooth, with no
peeling, corrosion, etc.
4.7.2 Immunity performance criteria
The performance criteria are as follows.
a) During the test, if the function or performance is normal within the limits
specified in the technical requirements, it can be determined as Grade A.
b) During the test, if the function or performance is temporarily reduced or lost,
but can be restored on its own, it can be determined as Grade B.
c) During the test, if the function or performance is temporarily reduced or lost,
but can only be restored after manual intervention or system reset, it can
be determined as Grade C.
d) During the test, if damages (loss of stored data) to the device (components)
or software, loss of functions and performance degradation occur, and
cannot be restored even with the help of manual intervention or system
reset, it can be determined as Grade D.
4.7.3 Electrostatic discharge immunity test
The requirements for the electrostatic discharge immunity test are as follows.
a) Test method. CARRY out the electrostatic discharge immunity test in
accordance with the provisions and methods of GB/T 17626.2. The severity
level is Level 4. The device enclosure is the site to be tested.
b) Qualification criteria. In the case of interference, the monitoring device shall
meet the requirements for performance criteria in Section 4.7.1.
4.7.4 RF electromagnetic radiation immunity test
The requirements for the RF electromagnetic radiation immunity test are as
