The test should be carried out in a clear and reproducible manner. The test shall be carried out item by item in order, and the test sequence is arbitrary. The description of the test, the test generator, the test method and the test arrangement are given in the EMC Basic Standards (see Chapter 2). Referenced in the following tables. The content of the EMC basic standard is not repeated here, but the content that needs to be modified or added in the actual test is given in this standard. 4.2 Detailed requirements 4.2.1 Electrostatic discharge (ESD) This test procedure shall be carried out in accordance with IEC 61000-4-2.2008 with the following modifications and explanations. Electrostatic discharge should only be applied to points or surfaces that the device may be exposed to during normal use, including those specified in the user manual. Something that may be touched, such as cleaning up or adding areas where consumables may touch when the EUT is powered. The number of test points depends on the specific equipment. The choice of test points should consider the requirements of 8.3.1 and A.5 of IEC 61000-4-2.2008. The electrostatic discharge test of the contacts is not required when the connector is disconnected. A.5 of IEC 61000-4-2.2008 gives a selection guide for actual test points. When choosing a test point, pay special attention to the keyboard and dial Number plate, power switch, mouse, drive slot, card slot, communication port and other parts. There should be two ways to discharge. a) Contact discharge on the conductive surface and the coupling plate. The EUT shall withstand at least.200 electrostatic discharges, including 100 positive and negative polarities, and shall be at least at the 4 test points of the EUT. Row. For benchtop equipment, one of the test points should be the center of the front edge of the horizontal coupling plate for at least 50 indirect discharges (positive and negative polarity) 25 times each). For all other test points, at least 50 direct contact discharges (25 positive and negative polarities) should be performed at each point. Suitable for all The areas that are exposed to the user during normal use are tested. If there is no suitable direct contact test point, it should be indirectly discharged. In this way, at least.200 discharges are performed [see IEC 61000-4-2.2008 for the method of discharging a vertical coupling plate (VCP)]. For contact discharges, the lower-level test requirements specified in Chapter 5 of IEC 61000-4-2.2008 do not apply. b) Air discharge of holes, slits and insulating surfaces. When it is impossible to conduct contact discharge test on some parts of the EUT, it is advisable to check the equipment and identify the user's easy contact and easy The point at which air breakdown occurs, for example, the gap at the edge of the button, the keyboard, and the outer casing of the handset. These parts are air-discharged test. 4.2.2 Electrical Fast Transient Pulse Group (EFT) The test method is specified in detail in GB/T 17626.4-2008, but the test arrangement for field measurement is not applicable to ITE. The test shall be carried out in accordance with the test procedures specified in GB/T 17626.4-2008 with the following modifications and instructions. --- When the EUT has multiple identical ports, only one of them is tested; ---Multi-core cables, such as 50 pairs of telecommunications cables, should be tested as a single cable. This test shall not separate or group cables; --- Only applicable to communication cables longer than 3m according to the manufacturer's specifications; --- The cable length between the EUT and the coupling should be between 0.5m and 3m and as short as possible. 4.2.3 RF continuous wave disturbance 4.2.3.1 Overview The frequency range of the radiation field test is 80MHz~1000MHz. The frequency range of the continuous wave conduction test is 0.15MHz~ 80MHz. Sweeping within the above frequency range as required, and may require more comprehensive and comprehensive at selected finite frequency points Functional test. The requirements for additional frequency selection tests are not applicable to all products and are only applicable to those specified in Appendix A. This requested product (specific requirements depend on the product). The selected frequencies are given in Tables 1 to 4. The dwell time at each frequency point should not be less than the time required to cause the EUT to act and respond, however, during each frequency sweep The dwell time at the rate point should not exceed 5 s. The time to make the EUT action should not be understood as the total time of a program or a cycle, but should be understood as a failure with the EUT. The reaction time is related. The clock frequency and other sensitive frequencies do not need to be evaluated separately unless required by the appendix to this standard. 4.2.3.2 Continuous wave radiation disturbance This test procedure shall be carried out in accordance with IEC 61000-4-3.2006. During the test, the EUT should be placed so that its four sides are exposed to the electromagnetic field in sequence. And assess the performance of the EUT at each location. If the most sensitive face of the EUT is known in the full frequency range (for example by pre-testing), then only the sensitive faces can be tested. in case It is not possible to determine the most sensitive faces (for example, different sensitive faces at different frequencies) and the four sides of the EUT should be tested. If the EUT is too large to be adequately irradiated by the antenna, or if the EUT is outside the range of the uniform domain, local irradiation should be used. test. In order to irradiate parts that were not previously in the uniform domain, the EUT can be rearranged to keep the surface to be measured uniform. Within the domain. 4.2.3.3 Continuous wave conducted disturbance Except as provided in 4.2.3.1, this test procedure shall be carried out in accordance with GB/T 17626.6-2008. 4.2.4 Power frequency magnetic field This test procedure shall be carried out in accordance with GB/T 17626.8-2006. The EUT shall be placed and connected in accordance with its functional requirements and placed in the center of the field coil (immersion method). Cables supplied by the EUT manufacturer should be used. If the EUT does not have a cable attached, the cable appropriate for the relevant signal should be selected instead. Devices with large physical dimensions do not need to be completely placed in the magnetic field, only sensitive devices (such as CRT monitors, if only It is the sensitive part) placed in the magnetic field. In this case, if the CRT monitor is connected to the ITE as a system, the CRT monitor Or sensitive devices can be tested separately. 4.2.5 Surge (shock) This test procedure shall be carried out in accordance with GB/T 17626.5-2008. 4.2.6 Voltage dips and short interruptions This test procedure shall be carried out in accordance with GB/T 17626.11-2008.5 ApplicabilityThe relevant ports of the EUT shall be tested according to Tables 1 to 4. Given the electrical performance and use of a particular EUT, certain tests may be inappropriate and therefore undesirable. In this case, need The decision to test certain specific ports for certain specific ports and their justifications are documented in the test report. For multi-function devices that are applicable to different terms of this standard and/or other standards, there is no need to physically change the inside of the device. To achieve its functional operation, it should be tested separately for each of its functions. As long as each function of the device under test matches For the terms/standards, the equipment shall be considered to comply with all the terms/standards. For example, for individuals with broadcast reception The computer, if it can run each function of the computer separately under normal working conditions, then it should first receive it in accordance with this standard. The test is performed under the condition that the function is not working, and then, according to CISPR20.2006, only the broadcast receiving function works. test. For devices that cannot be operated independently for each function, or for a special function to operate independently, the device will not meet its main function. A device that can save measurement time when several functions are running at the same time, if the device is still full when running the necessary functions The relevant provisions/standards are considered to meet the requirements. For example, a personal computer with broadcast reception cannot be independent of The broadcast receiving function is implemented under the condition of the calculation function, so the personal computer can be calculated according to this standard and CISPR20.2006 The function is tested while the function of the broadcast reception function is running at the same time. Due to different test specifications and/or test arrangements and/or performance criteria, when the relevant functions of multi-function devices are tested according to different standards Inspection time, allows specific ports, frequencies or functions to be not required in the relevant standards (for example, according to this standard, the broadcast receiving function is included. When the device is measuring, the requirements in Table 2 do not apply to the antenna port or the broadcast receiving function is not evaluated). Whether it is necessary to meet multiple criteria in the appendix, depending on the EUT. For example, the TTE connected to the LAN should meet Appendix A and Performance criteria specified in Appendix C.6 State of the EUT during the test6.1 General status The test shall be carried out in the most representative manner consistent with the typical application and with all major functions operating. Test samples should be configured in the actual typical installation. If the EUT is part of the system or can be connected to an auxiliary device, the EUT shall be as described in Chapter 8 of GB 9254-2008. In a similar manner, the necessary auxiliary equipment is connected and tested in a representative minimum configuration. The configuration and operation mode of the EUT during the test shall be accurately indicated in the test report, and each function of the equipment shall be tested and Not always possible, in this case you should choose the most rigorous way of running. If the EUT is equipped with more terminals or ports with more similar connection types, you should select a sufficient number of terminals or ports to simulate Practise the actual working state and ensure that all different types of terminals are included. Spiral cables (such as keyboard cables) should not be intentionally stretched during the test. For this type of cable, the length specified in Table 2 is stretched The length of the state. Test equipment or auxiliary equipment connected to the EUT (such as NT or simulator) should have no effect on the test results. If the external protection device or protective measures are specified in accordance with the manufacturer's specifications or specified in the user manual, then The test requirements of this standard apply only in the case of external protective devices or protective measures. During the test, the environmental conditions and supply voltage shall be kept within the scope of work specified in the product specification, except in the basic standard. Another explanation.
