At present, most of the products sold in the market are copper faucets, whether in Europe, America or my country. The main materials of copper faucets are copper and zinc, commonly known as brass. A small amount of lead needs to be added during the production of faucets. Lead can not only improve the cutting performance of brass, but also become a “killer” that endangers human health. . As we all know, lead in faucets is the most harmful. In recent years, not only inland, but also in Hong Kong and Taiwan have also been exposed to lead in faucets. In December 2014, the mainland revised the “Ceramic Sheet Sealing Faucet” “National standard, and Taiwan has also recently issued a new standard for faucets, stipulating that the upper limit of lead in faucets is 0.25%.
“Ceramic sheet sealed faucet” national standard 66 companies meet the certification
As early as December 2014, the GB18145-2014 “Ceramic Sheet Sealing Faucet” national standard, known as “the most stringent faucet standard in history” in our mainland, has been officially implemented. This standard provides a test method and limit for lead content in American faucets. The value requirements are in line with the standard NSF/ANSI 61. At that time, 66 companies passed product certification (all those big brands). According to the “Regulations for the Approval and Implementation of Metal Pollutants Released from Ceramic Sheet Seal Faucets”, the China National Union Trust Certification Center set out technical requirements, The process requirements, process control requirements, valve body material requirements, testing equipment requirements, factory confirmation requirements and quality assurance capabilities requirements have been strictly audited and sampled. After technical assessment, a total of 66 companies have met the certification requirements and were approved for registration. However, in 2015, the exposed news about lead in faucets could not be counted with one hand, and there were many big brands among them.
Taiwan’s new faucet standards are in line with the international bathroom market
In October 2015, Taiwan reported that there was a problem with lead-containing faucets, which caused panic among the people. In order to let Taiwanese people drink water at ease and prevent low-priced and inferior products from flowing in the market, the Bureau of Industry of the Ministry of Economic Affairs commissioned the development of Taiwan Eisai from the Metal Industry Research and Development Center. The Institute of Testing and Testing (TPL) has assisted the Water Hardware Association to establish a sanitary product verification mechanism so that consumers can purchase safe faucet products according to their needs. Now the Water Hardware Association has developed a sanitary product verification mechanism. The Bureau of Industry stated that the current advanced countries in the world have stricter and stricter quality requirements for green faucets and drinking water safety, and most of them are based on regulations formulated by the National Sanitation Foundation (NSF).
The Bureau of Industry stated that it had previously invited the Bureau of Standards, Metrology, Inspection and Quarantine, the Water and Hardware Industry Development Association, and industry representatives to consult the above-mentioned Water and Hardware Association sanitary product verification mechanism for several consultations on the CNS 8088 faucet testing specifications. Among them, the new version of the faucet inspection specification CNS 8088 has been announced by the Bureau of Standards, Metrology and Inspection on November 11 last year after many expert, scholar and industry consultation meetings.
According to the content previously announced by the Standards, Inspection and Quarantine Bureau, the new version of the specification incorporates the internationally synchronized faucet toxic substance dissolution test method, except for the revision of the lead content of the faucet product to less than 5 micrograms (ppb, 5 parts per billion), and the number Ten organic and inorganic semi-volatile substances are included in the standard, and there are concentration limits. In addition, with reference to US regulations, the lead content used in the manufacture of faucet materials is limited to 0.25% or less. The Bureau of Industry stated that in the future, high-quality faucets produced in Taiwan will be able to integrate with the international sanitary ware market as long as they pass the CNS 8088 inspection standard. In addition to enhancing the competitiveness of the domestic water hardware industry, it can also maintain the health and safety of drinking water for the people.
Taiwan’s new standard this time is slightly different from the mainland’s new national standard. The main difference between the two is that the metal pollutants on both sides of the Taiwan Strait have given limits for 17 metal elements. Except for the same limit for 15 elements, Taiwan has The statistical value of zinc is determined to be below 300.0ug/L, chromium is below 5.0ug/L, and the chromium on the mainland is below 10.0ug/L. In particular, the limit value of hexavalent chromium is below 2.0ug/L. .
