Scope
This part of IEC 62321 specifies a standard and two information technologies for the determination of polybrominated biphenyls (PBB) and diphenyl ethers (PBDE) in polymers for electrical products The gas chromatography-mass spectrometry (GC-MS) determination method is suitable for the determination of PBB and PBDE Appendix A and C use ion attachment mass spectrometry (IAMS), direct injection probe (DIP), and high-pressure liquid chromatography combined with photodiode array ultraviolet detector (HPLC-PDA/UV) methods. These technologies have practical value as fast, qualitative, or semi quantitative methods, but are limited by interference or the number or type of polybrominated biphenyls and polybrominated diphenyl ether compounds within their scope The ion attachment mass spectrometry (IAMS) technique is limited to the determination of flame retardant mixtures of decabromodiphenyl ether, octabromodiphenyl ether, and pentabromodiphenyl ether. The use of this method to determine other polybrominated biphenyls or polybrominated diphenyl ethers has not been evaluated High pressure liquid chromatography technology is limited to the determination of mixtures of flame retardants of decabromodiphenyl ether, octabromodiphenyl ether, decabromodiphenyl ether, and octabromodiphenyl ether technology. The determination of other polybrominated biphenyls or polybrominated diphenyl ethers has not been evaluated
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
