Electromagnetic compatibility test and measurement technology
Electrostatic discharge immunity test
1 Scope
This part of GB/T 17626 stipulates that electrical and electronic equipment is subject to static electricity directly from the operator and its operators to adjacent objects.
The immunity requirements and test methods for discharge also specify the range of test levels and test procedures for different environments and installation conditions.
The purpose of this section is to establish a common and reproducible benchmark to evaluate the performance of electrical and electronic equipment subjected to electrostatic discharge.
In addition, it includes electrostatic discharges that can occur from the human body to objects that are close to critical equipment.
The provisions of this section include.
--- Typical waveform of discharge current;
---The scope of the test level;
---Test equipment;
---Test configuration;
---Test procedure;
--- Calibration procedure;
--- Measurement uncertainty.
This section sets forth technical requirements for the “laboratory” test and the “test after the installation of the equipment”.
This section does not regulate the testing of special equipment and systems. Its main purpose is to provide recommendations for all relevant professional standardization technical committees.
For a general basic principle. The relevant professional standardization technical committee (or the user and manufacturer of the equipment) is responsible for selecting the test and determining
The severity of the test conditions.
In order not to interfere with the tasks of coordination and standardization, it is highly recommended that the relevant professional standardization technical committee or users and manufacturers consider
In the future work or the revision of the original standard) the relevant immunity test specified in this section is used.
