Faucets are also called faucets. In addition to quality indicators such as water saving, sikkerhet, and beauty, the amount of heavy metal precipitation in faucets has become a health and safety indicator that people are most concerned about. The Zhejiang Provincial Bureau of Quality and Technical Supervision recently spot-checked faucet products and found that the unqualified rate was 100%, and the risk of heavy metals exceeding the standard was high.
Zhejiang Provincial Quality Supervision Bureau and Ningbo Quality Inspection Institute recently conducted a special supervision and spot check on the quality of faucets in Yongkang Hardware City. Det er 15 production companies involved, and the places of production include Shanghai, Zhejiang, Guangdong, Fujian og andre 4 steder. Det er 15 batches of unqualified batches, and the batch unqualified rate is 100%. Among the unqualified products, alle gjenstander av “krav til materialhygiene” var ukvalifiserte, 14 partier av “korrosjonsbestandighet av belegg og plettering” varene var ukvalifiserte, og 10 partier av “merking” varene var ukvalifiserte.
Ukvalifisert “krav til materialhygiene” betyr at tungmetaller er kjent for å overgå standarden, som vil skade forbrukernes helse. Inspeksjonen fant at blant produktene som ble tatt prøver denne gangen, zinc alloy materials were used as the main material of the products actually accounted for 50%. Zinc itself is a heavy metal, and excessive amounts can cause zinc fever. For det andre, products with unqualified “belegg og plettering korrosjonsbestandighet” are easy to rust after use. In addition to affecting the appearance, they may contain toxic components after corrosion. For eksempel, patina has strong toxicity.
It is reported that on December 1, 2014, kranen standard kalt “den strengeste i historien”-GB18145-2014 “Keramisk tetningsark Kran Standard” began to be implemented. The new national standard supplements and modifies the existing standards in terms of water-saving performance and quality of faucets. Sammenlignet med den opprinnelige standarden, it increases the precipitation limits for 17 metallforurensninger som bly, krom, arsenikk, mangan, og kvikksølv. And as a mandatory clause. Blant dem, mengden av “bly” that has attracted much attention is specified to be no more than 5 mikrogram/liter, som er i samsvar med gjeldende amerikanske standarder og er verdens høyeste. Den nye standarden gjelder kraner av alle materialer.
Zhejiang Provincial Bureau of Quality Supervision reminds consumers that when purchasing faucet products, de bør kjøpe kvalifiserte produkter som selges i vanlige kanaler og produseres av vanlige produsenter, and it is best to choose products produced according to the new standard after December 1, 2014. Choose a faucet with copper alloy and stainless steel as the main material; the spray surface structure should be fine, smooth and uniform, and there should be no defects such as sagging, bottoming, etc., and there is no burr or grit feeling on the hand; visually inspect the thread surface for obvious dents, broken teeth, etc. For defects, it is recommended to choose thread with wall thickness.
