Response to EU Environmental Protection Directives Ningbo Breakthrough Technology Detection Difficulties

According to news from the Ningbo Inspection and Quarantine Bureau's technical center, the technical staff of the center has stepped up the investigation of the test items specified in the two directives of the European Union. At present, four heavy metal elements, polybrominated biphenyls (PBBSs) and polybrominated diphenyl ethers (PBDES) can be applied to plastic products. ) Conduct tests and issue laboratory reports to provide technical support for relevant export enterprises in Ningbo. The Technology Center of Ningbo Inspection and Quarantine Bureau has officially provided related inspection services for the three companies.

The European Union’s ROHS Directive issued at the beginning of last year requires that, as of July 1, 2006, electrical and electronic products placed on the EU market must not contain six hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. According to the attachment requirements of the bulletin directive, the products involved will include large household appliances, small household appliances, IT and communications equipment, consumer products, lighting equipment, electrical and electronic tools, toy leisure and sports equipment, medical equipment, monitoring equipment, and vending machines. And other top ten products.

Ningbo is a region with a high export volume of electromechanical products, accounting for about half of total exports, and the EU is one of the major export markets. The effective and implementation of the above two directives will inevitably greatly affect the export of mechanical and electrical products. The technical personnel of the Ningbo Inspection and Quarantine Bureau have been very concerned since the publication of the EU announcement, but since the two major classes of substances, PBBS and PBDES, each contain 209 isomers, detection and analysis are quite difficult. Since 2004, technical personnel have expanded their peer-to-peer technical exchanges by investigating related literature at home and abroad, and have actively conducted research on the detection methods. Promptly purchasing standard substances and reagents, making full use of existing large-scale instrumentation equipment to carry out research on detection methods, overcoming many technical difficulties and achieving phased results. The use of atomic spectroscopy in the determination of four heavy metals in plastic products, hexavalent chromium is used to determine the total amount to meet the needs; for polybrominated biphenyls (PBBS) and polybrominated diphenyl ethers (PBDES) using gas chromatography - mass spectrometry to detect .
