GB18499-2008/IEC61543:1995 replaces GB 18499-2001 and is used to ensure that the rated voltage does not exceed 440V. It is mainly used as an electromagnetic compatibility (EMC) protection device for residual current action to protect the human body from electric shock. When required by product standards, this standard is applicable and used in conjunction with product standards. Currently, the applicable standards include GB 16916 for residual current operated circuit breakers (RCCBs) without overcurrent protection for household and similar purposes; GB 16917 for residual current operated circuit breakers (RCBOs) with overcurrent protection for household and similar purposes, and GB 20044 for mobile residual current devices (PRCDs) without overcurrent protection for household and similar purposes. This standard also applies to residual current devices (SRCDs) installed in or assembled with fixed sockets without overcurrent protection, as well as other RCDs with overcurrent protection
1. The main differences between GB 18499-2008 and GB 18499-2001 are as follows:
1.1 In the introduction, it is clear that the EMC characteristics of products are generally related to design and not affected by manufacturing processes. Therefore, the testing of this standard is carried out during design validation, and the testing is only repeated when product modifications affect its EMC performance.
1.2 added immunity tests for conducted sine wave voltage and current Added surge immunity test in 1.3 Added RF electromagnetic field immunity test in 1.4 1.5 added common mode conducted disturbance tests in the frequency range below 150kHz2. Conducted sine wave voltage or current immunity test
Test basis: GB18499-2008T2.1
Conduct the test according to the requirements of GB/T17626.6-1998.
Test conditions: I Δ N ≥ 30mA, test field strength: power supply, signal port: 3V (e.m.f, rms, unmodulated) I Δ N< 30 mA, test field strength: power supply, signal port: 1V (e.m.f, rms, unmodulated)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 problemsBaijian 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 China
