For the sake of use, some terms and definitions in GB/T 4365-2003 are repeatedly listed as follows. 3.1 Air discharge method Method of testing in which the charged electrode of the test generator is moved towards the EUT until it touches the EUT. 3.2 Antistatic material Material exhibiting properties which minimize charge generation when rubbed against or separated from the same or other similar materials.4 GeneralThis standard relates to equipment, systems, subsystems and peripherals which may be involved in static electricity discharges owing to environmental and installation conditions, such as low relative humidity, use of low-conductivity (artificial-fiber) carpets, vinyl garments, etc., which may exist in all locations classified in standards relevant to electrical and electronic equipment.5 Test LevelsContact discharge is the preferred test method. Air discharges shall be used where contact discharge cannot be applied. Voltages for each test method are given in Table 1.The voltages shown are different for each method due to the differing methods of test. This does not imply that the test severity is equivalent between test methods.6 Test Generator6.1 General The generator shall meet the requirements given in 6.2 when evaluated according to the procedures in Annex B. Therefore, neither the diagram in Figure 1, nor the element values are specified in detail. 6.2 Characteristics and performance of the ESD generator The test generator shall meet the specifications given in Tables 2 and 3.Figure 2 shows an ideal current waveform and the measurement points referred to in Tables 2 and 3.7 Test Setup7.1 Test equipment The preferred test method is that of type tests performed in laboratories. The EUT shall be arranged in accordance with the manufacturer's instructions for installation (if any). 7.2 Test setup for tests performed in laboratories 7.2.1 Test requirements The following requirements apply to tests performed in laboratories under environmental reference conditions outlined in 8.1.8 Test Procedure8.1 Laboratory reference conditions 8.1.1 Environmental parameters In order to minimize the impact of environmental parameters on test results, the tests and calibration shall be carried out in climatic and electromagnetic reference conditions as specified in 8.1.2 and 8.1.3. 8.1.2 Climatic conditions The EUT shall be operated within its intended climatic conditions. In the case of air discharge testing, the climatic conditions shall be within the following ranges. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
