Scope
This part of GB/T 17626 covers the immunity requirements and test methods for electrical and electronic equipment to repetitive electrical fast transients. In addition, the range of test levels and the determination of test procedures were also specified The purpose of this section is to establish a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control, and grounding ports of electrical and electronic equipment when subjected to electrical fast transient pulse groups. The test method specified in this section describes a consistent method for evaluating the immunity of equipment or systems to defined phenomena
Note: As stated in IEC Guide 107, this part is the fundamental standard for electromagnetic compatibility and is intended for use by various product committees. IEC guideline 107 also stipulates that the product committee is responsible for determining whether to apply this immunity test standard, and if used, for determining the test level and performance criteria for penetration. The National Electromagnetic Compatibility Standardization Technical Committee and its sub technical committees are willing to cooperate with the Product Committee to evaluate the special immunity requirements of their products This section specifies:
- Test voltage waveform
- Range of test levels
- Test equipment
- Calibration and verification procedures for testing equipment
- Test layout
- Test procedure This section provides technical specifications for laboratory and on-site testing The following documents are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
