Excessive heavy metal faucet

Sanitary products are related to the health and safety of the people. At present, the development of the domestic sanitary ware industry is not very standardized. There is still a big gap in modern sanitary technology compared with developed countries such as Europe and the United States. The quality and safety of household sanitary products are obviously insufficient.

Promei faucet hexavalent chromium exceeds the standard for two consecutive years on the quality black list

In 2013, the Shanghai Municipal Bureau of Quality Supervision conducted special supervision and spot checks on the quality of faucets produced and sold in Shanghai. A trademark produced by Zhuhai Pulemei Kitchen and Bath Co., Ltd. is Pulemei, and the specification model is DN15 single handle dual control 70101G, the kitchen faucet with the production date or batch number 2013-1-15, was detected to exceed the standard of chromium (hexavalent chromium) content, and the pipe thread accuracy was detected as unqualified, because the two indicators were unqualified, it was specially marked as ” The quality problem is serious”.

The Shanghai Municipal Bureau of Quality Supervision stated in the notification that the chromium (hexavalent chromium) project tested the amount of hexavalent chromium precipitated in the product soaking water. Ingestion of hexavalent chromium may cause thickening of the oral mucosa, nausea, severe abdominal pain and liver Swelling, accompanied by symptoms such as shortness of breath, pulse rate, and meat cramps, seriously endangers human health. Pipe thread precision inspection is the thread precision quality. Failure of this item may cause the product to leak water or interface burst.

One year later, in a special supervision and spot check conducted by the Shanghai Municipal Bureau of Quality Supervision in 2014, Zhuhai Promet was again found to have excessive chromium (hexavalent chromium) content. On August 18, the Shanghai Municipal Bureau of Quality Supervision issued the “2014 Shanghai Water Tap Product Quality Supervision Spot Check Results”, which showed that a manufacturer (nominal) is “Zhuhai Pulemei Kitchen & Bath Co., Ltd.” and the trademark is ” A kitchen faucet with a specification model of “DN15, 70118A”, a production date or a batch number of “2013-11-15” was judged as a substandard product due to excessive chromium (hexavalent chromium).

The carcinogen hexavalent chromium detected in the faucet exceeds the standard and is harmful to health

Promei has always been advertised as “the world’s leading brand of stainless steel sanitary ware”, and has long promoted “zero lead health” as its selling point. In two years, it is really shocking to be detected twice in a row that the content of chromium (hexavalent chromium) exceeds the standard. Chromium is a white metal element with two valence states, namely trivalent chromium and hexavalent chromium. Trivalent chromium is not harmful to humans, but under certain circumstances, the hexavalent chromium produced after oxidation is a carcinogen that is harmful to humans. According to industry experts, if unqualified pipe thread accuracy only affects product performance, then excessive chromium (hexavalent chromium) may endanger people’s health.

It is just such a sanitary ware company that vigorously promotes “zero-lead health” and emphasizes that its products do not contain lead. It has been repeatedly detected that the content of chromium (hexavalent chromium) exceeds the standard, which shows the shortcomings of its product quality monitoring process.

Stainless steel faucet is not “zero lead” Promet’s one-sided publicity misleads consumption

All along, a major feature of business propaganda is to one-sidedly promote that one indicator is qualified, while ignoring or omitting other indicators. And to measure whether a faucet is qualified, the amount of lead precipitation is only one of the factors. There are other metals in the product, and poor control may also cause harm to the human body.

Recently, when the staff of China Quality Miles visited the home building materials stores in Beijing, they found that the huge advertisement of Promite “0 Lead Lead” and “0 Lead Health” was very eye-catching. So, is the stainless steel faucet really “zero lead”? How true is it behind the hype?

Prior to this, CCTV’s “Is it Real” program conducted sampling tests on 14 brand faucets. The results of the sampling showed that all the faucets contained lead. The National Building Materials Industry Construction Hardware Plumbing Products Quality Supervision and Inspection Center is responsible for this test. The test is based on the JC/T1043-2007 “Limit of Lead Release from Water Taps”. This standard stipulates that the amount of lead released from water taps is 11 micrograms/liter. According to this standard, faucet monitoring needs to be rinsed, soaked for 19 days to simulate domestic water, take water samples at different periods of time, and chemically analyze the amount of lead precipitation. After 21 days of testing, the test results showed that the 14 brand faucets submitted for inspection contained lead, and the amount of lead precipitation in stainless steel faucets was indeed lower than that of copper faucets. But it’s not that stainless steel faucets are lead-free. The “zero lead” promoted unilaterally by businesses such as Promax is not in line with the truth. It is just a gimmick of the business.

According to industry insiders, in a strict sense, stainless steel also contains lead, but it is low-lead. It does not mean that the material does not contain lead. Stainless steel does not contain lead. The pipes inside the stainless steel faucet, the plastic rubber ring, and the plastic of the metal mouth also contain lead. lead. The biggest problem with stainless steel is that heavy metals exceed the standard. Except for lead, excessive heavy metals are more terrifying. The comprehensive quality of kitchen faucet products requires strict control of lead content and other elements such as chromium, manganese, arsenic, etc., which may cause harm to people’s health. Industry experts remind that consumers do not need to blindly pursue “zero lead” when buying faucets, and businesses are obliged to provide consumers with comprehensive and objective information, rather than one-sided exaggerated publicity and misleading consumption.

The introduction of the new national standard will effectively curb the phenomenon of excessive heavy metals in faucets

It is reported that the new national standard “Ceramic Sheet Sealing Faucet” has been formally implemented on December 1, 2014. Among them, the faucet heavy metal precipitation, sealing performance, flow rate, and life are mandatory terms, and for the first time it is mandatory that the statistical value of lead precipitation in the faucet should not be greater than 5 micrograms/liter. The new national standard increases the detection categories of metal content in faucets to 17 types. In addition to lead, 16 metal content such as chromium and manganese are included in the key detection objects. The limit standards for metal pollutants will be in line with European and American standards.

After the implementation of the new national standard, the appearance and quality of faucets on the market are expected to be improved, and it can promote enterprises to strengthen management and product upgrades, which will play a vital role in the standard operation of the entire sanitary ware market and make China’s faucet industry a step forward International standards, and the chaos of excessive heavy metals in domestic taps will also be effectively curbed.
