The water flowing from the faucet at home may exceed the lead content. Last year's "faucet lead out of standard" incident, I believe everyone still remembers: a lead detection, 13 kinds of household faucets have 9 kinds of unqualified, of which the highest exceeds the national standard 34 times, including many well-known brands. However, this phenomenon will wait for change soon. Recently, the state officially approved the new national standard for "ceramic sheet sealing nozzle" and said that it will be officially implemented on December 1. The new national standard has strict regulations on the precipitation of various heavy metal elements in faucets.
Recently, the country officially approved the new national standard for "ceramic sheet sealing nozzle", and said that it will be officially implemented on December 1. The six-month period from release to implementation is an adaptation period for companies in the industry to become familiar with and implement the new standards. According to Xie Xin, secretary general of the Sanitary Ware Committee of the All-China Federation of Industry and Commerce, the standard will be the highest testing standard in the world, even exceeding the US testing standard.
It is understood that the current two domestic standards concerning the heavy metal content of faucets are recommended standards, and the implementation is not strong enough. Compared with the old national standard, the new national standard has many modifications, and many items have been added or deleted. In particular, corresponding policies were introduced in response to the hot event of “lead faucet exceeding standard†in the industry last year. First, strictly control and clearly stipulate the precipitation of heavy metals. In the previous national standard "Lead Precipitation Limit of Water Spout", only the precipitation concentration of water soaked in water spout was ≤0.005mg / L, and for other metal elements, there were no other regulations. However, in the new national standard, in addition to lead, it also sets mandatory standards for the precipitation of other elements such as manganese and chromium. Second, it pays attention to environmental protection and clearly requires water-saving nozzle flow. The new standard specifies different flow requirements for different nozzles. According to the flow rate, the four types of ordinary washing faucet, wash basin faucet, kitchen faucet, and bidet faucet are divided into water-saving type and ordinary type. The flow requirements of four situations: full heat position, mixed water position and shower position with and without shower. Then, performance usage is more secure. In the previous standard, there was no much requirement for the sealing performance of the top spray shower and the hand shower changeover switch. Therefore, if the sealing performance of the shower changer is not good, when adjusting the amount of water, there will be dangerous situations such as deformation, burst and leakage. The new national standard adds the sealing performance requirements of these two products.
