VIGA krantillverkare 
The Ningbo Quality Inspection Institute recently conducted a special retrospective supervision and spot check on the product quality of faucets (kran) in Yongkang Hardware City, involverande 15 tillverkare. The origins include Shanghai, Zhejiang, Guangdong, Fujian och andra 4 plats, and the number of unqualified batches is 15 Batch, batch failure rate is 100%.
Among the unqualified indicators, alla artiklar av “Materialhygienkrav” var okvalificerade, 14 satser av “korrosionsbeständighet av beläggning och plätering” items were unqualified and 10 satser av “märkning” Objekt var okvalificerade.
Okvalificerad “Materialhygienkrav” betyder att tungmetaller ofta är kända som överskrider standarden, vilket kommer att skada konsumenternas hälsa. Inspektionen fann att bland de produkter som provades den här gången, zinc alloy materials were used as the main product material accounted for 50%.
Although the relevant standards do not specify which materials to use, the use of zinc alloy materials is likely to exceed the standard for heavy metals, and zinc itself is a heavy metal, and excessive amounts will cause zinc fever. För närvarande, the most widely used faucet materials should be copper alloy and stainless steel.
Faucets with unqualified “beläggning och pläteringskorrosionsmotstånd” are prone to rust after use, which affects the appearance. After corrosion, they may also contain toxic components, such as patina, which is highly toxic.
CCTV has repeatedly reported on heavy metal incidents such as excessive lead in faucets. This is also a catalyst for the introduction of the new version of the “Standard for Ceramic Sealing Sheet Faucets”. Den december 1, kranstandarden som heter “Det strängaste i historien”-GB18145-2014 “Keramisk tätningsark kranstandard” came into effect. The new national standard supplements and modifies existing standards in terms of water-saving performance and quality of faucets. Jämfört med den ursprungliga standarden, the biggest change is the addition of 17 metal pollution such as lead, krom, arsenik, mangan, och kvicksilver. The amount of precipitation is a mandatory clause. Bland dem, mängden av “leda” that has attracted much attention is not more than 5 mikrogram/liter, vilket överensstämmer med de nuvarande amerikanska standarderna och är världens högsta. Den nya standarden gäller för kranar för alla material.
In order to promote the implementation of the new standards, the first new national standard certification for faucets has also been launched. “Certifikat för metallföroreningsutfällningsgräns för keramisk ark tätningskran” is the first voluntary product certification for the new national standard of faucet. I framtiden, it may play the role of “3C certification in the bathroom industry” and become the market access for faucet products. certificate. The first batch of certified companies meeting the national standard will be announced at the end of the year.
The Provincial Quality Supervision Bureau stated that when consumers buy faucets, De bör köpa kvalificerade produkter som säljs i vanliga kanaler och produceras av vanliga tillverkare. It is best to choose products produced according to the new standard after December 1, 2014, and do not unilaterally pursue low prices. . Try to buy a faucet with copper alloy and stainless steel as the main material and excellent appearance quality.
