Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: according to customer needs and experimental complexity, quotation
sample size: according to the samplesize to choose the sample or door-to-door
display style: electronic version
Testing cycle: 3-15 working days (expedited).
Scope
This part of GB/T 17626 specifies the immunity of equipment under operating conditions to pulse magnetic field disturbances in the following places
Requirements:
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 electrical and electronic equipment for household, commercial, and industrial use in pulsed magnetic fields
This section specifies the following:
- recommended test levels;
Test equipment- Test configuration
- Test procedure

Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in ChinaTesting process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
