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.

Table 1 -- Test Items

Serial

No. Test items Type test Exit-factory test Commissioning test Field test

1 Structure and appearance inspection - - - -

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

follows.

a) Test method. CARRY out the RF electromagnetic radiation immunity test in

accordance with the provisions and methods of GB/T 17626.3. The severity

level is Level 3. The device enclosure or core component 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 Sectio...
