It is understood that the current two domestic standards involving heavy metal content in faucets are both recommended standards, and the implementation is not strong enough. Compared with the old national standard, the new national standard has many modifications, adding and deleting many items. Especially in response to the industry’s “faucet lead-excess” popular incident last year, corresponding policies were issued. First, strictly control and clearly stipulate the precipitation amount of heavy metals. In the previous national standard “Lead Separation Limits in Faucets”, only the concentration of lead precipitation in the faucet immersion water is 0.005mg/L, and there are no other regulations for other metal elements.
However, in the new national standard, in addition to lead, there are also mandatory standards for the precipitation of various elements such as manganese and chromium; secondly, it pays attention to environmental protection and clearly requires water-saving nozzle flow. The new standard specifies different flow requirements for different taps. According to the flow rate, the four types of faucets: ordinary washing faucet, lavatory faucet, kitchen faucet, and bidet faucet are divided into two types: water-saving type and ordinary type. There are four flow requirements for full heat position, mixed water position and shower position with and without shower. Then, performance usage is more secure. In the previous standard, there were no requirements for the sealing performance of the top spray shower and the hand shower switch. Therefore, if the sealing performance of the shower transfer switch is not good, when the water volume is adjusted, dangerous situations such as deformation, bursting and leakage will occur. The sealing performance requirements of these two products have been added to the new national standard.
Faucet costs may rise
Xie Xin, secretary-general of the Sanitary Ware Committee of the All-China Federation of Industry and Commerce, said in an interview with a reporter from Chengdu Commercial Daily that the introduction of the new national standard for faucets is a matter of course and plays a very important role in improving the quality of China’s faucet industry. This standard should be the highest standard in the world at present, and its testing range even exceeds the 6 items of the American standard. The extra 6 items are mainly focused on the inspection of stainless steel faucets.
Xie Xin said that 35% of the global faucet production is concentrated in China, which covers almost all well-known brands. This shows that the production of faucets in China is in the most advanced position in terms of standards and technology, but it is undeniable that every new standard The introduction is a reshuffle of the industry and a survival of the fittest in the industry. The new standards will undoubtedly play a better role in protecting consumers’ rights and interests. For production companies, they have put forward higher requirements in terms of production skills, production processes, and production equipment. It will cause a rise in costs, and the direct response is that the price of faucet products may rise to a certain extent in the early period after the introduction of the new national standard. However, for the introduction of the new national standard, Xie Xin believes that the new standard puts forward higher requirements for manufacturers. The formulation of the new standard is only one aspect, and the key lies in how the standard is more effectively implemented.
Consumers must remember to look and hear
The introduction of the new national standard for faucets is undoubtedly an extra guarantee for consumers. However, in the face of many branded faucets in the market, how can we buy better quality products? A “seeing, hearing and asking” is popular in the industry.
Hope, as the name implies, when choosing a faucet, it is necessary to check whether the electroplating surface is evenly glossy, whether there are any defects such as peeling, cracks, dark spots and obvious pitting.
Smell, when buying a faucet, you need to distinguish it by smell. Smell the nozzle of the faucet, and buy it with caution.
Ask, when purchasing, you should ask the salesperson more about the relevant data of the product, the product test report, the brand logo and the after-sales service card. If the test report confirms that the product is qualified, you can use it with confidence.
Cut, usually good faucets are usually very heavy, so you can also weigh the weight of the faucet by hand when purchasing.
In addition, experts also said that for the sake of cheapness, you must not buy unknown products from irregular businesses, so as to avoid buying fake and shoddy products.
Drain overnight water to reduce lead hazards
Drinking water that contains too much lead can cause lead poisoning, which will not only affect the intellectual growth of the drinker, but also seriously affect the health of the child, and the impact on children will be even greater. Scientific data shows that severe lead pollution often endangers human reproductive capacity, kidney function and nervous system. Children and pregnant women are the biggest victims of lead poisoning.
How to achieve safer water in family life? It has become a big problem for consumers. Xie Xin, secretary-general of the Sanitary Ware Committee of the All-China Federation of Industry and Commerce, said in an interview that when buying, try to choose some large and relatively well-known brands, and pay more attention to product test reports, brand logos and after-sales service cards. At the same time, pay attention to the selection of accessories such as hoses and angle valves, because poor quality hoses and angle valves may retain some water, and lead will only be precipitated when water is stored. In the process of use, “draining the overnight water” is a relatively simple and practical method. Because the faucet itself will accumulate a certain amount of water, heavy metals such as lead will be precipitated over time. Generally speaking, when using the faucet in the morning, drain the water accumulated in the faucet overnight before using it.
