How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Report qualification: CNAS, CMA, CAL, etc
. Presentation style: electronic
version of the testing cycle: 3-15 working days (expedited can be expedited)
Testing cost: Quotation according to customer needs and experimental complexity
Sample size: Choose to send samples or visit the door according to the sample size
Scope
This part of GB/T 17626 specifies the immunity requirements for equipment under operating conditions to pulse magnetic field disturbances in the following places:
- industrial facilities and power plants
- Medium voltage and high voltage substations The applicability of this section is determined by the phenomenon of equipment installed in different locations, as described in Chapter 3 This section does not consider disturbances caused by capacitive and inductive coupling in cables or other parts of on-site facilities Conducted disturbances related to this are considered in other EMC standards The purpose of this section is to develop a universal and reproducible benchmark to evaluate the performance of household, commercial, and industrial electrical and electronic devices exposed to pulsed magnetic fields
This section specifies the following:
- recommended test level;
- Test equipment
- Test configuration
- Test procedure
