Who dominated the national standard for stainless steel utensil containers?

Supor (002032. SZ) The storm caused by the "problem pot" has pushed the industry's standard stainless steel material issues into public opinion.

A person in charge of the China National Hardware Association once said that the Ministry of Health had revised the "Hygienic Standard for Stainless Steel Food Containers" (GB9684-1988) (hereinafter referred to as the "88 Standard") in 2010, and it has not yet been formally promulgated.

According to the revised standard reviewed by the reporter of the First Financial Daily, the “Stainless Steel Food Container for National Food Safety Standards” (Draft for Soliciting Opinions) (hereinafter referred to as the “Draft for Soliciting Opinions”) significantly reduced the number of foodstuffs. Container requirements for the use of stainless steel materials.

"It can be said that some companies in this industry have abducted relevant national standards in an attempt to reduce the production process materials and hygiene standards." A senior home appliance industry analyst told the newspaper yesterday.

The new revised standard reduces the use of material requirements. "Last year, the relevant departments and units did not seek our opinions when we revise the 88 standard. We once offered to comment on the standard amendment, but no one responded." Special Steel Association of China Stainless Steel Branch An insider told the newspaper yesterday. The branch is currently one of the most authoritative departments in the domestic stainless steel industry. The downstream companies such as food containers are only consumers of stainless steel.

Because the 88 standard imposes stringent regulations on the stainless steel materials used in stainless steel food container containers, coupled with the dramatic increase in nickel prices in recent years, the entire stainless steel food container industry is sceptical about this standard.

There are two current standards for stainless steel food container containers: one is the 88 standards issued by the Ministry of Health; the other is the industrial standards issued by the Ministry of Light Industry in 1992 [QB/T 1622.5-1992] to [QB/T 1622.11-1992]. Stainless steel vessel "standard (hereinafter referred to as "92 standard").

"The requirements of the 88 standard and the 92 standard for stainless steel food containers are no problem," said the stainless steel branch.

Since 2007, the downstream industry has begun to modify the 88 standard. Shanghai Food and Drug Administration, Shanxi Provincial Center for Disease Control and Prevention, Chaoan Stainless Steel Industry Association, and Zhejiang Supor Co., Ltd. formed a drafting group.

Informed sources disclosed to this newspaper that if companies participate in the drafting of an industry standard, they need to pay, "Of course, this standard is definitely beneficial to the enterprise."

According to the consultation draft, the drafting group has sent the draft for consultation to 28 relevant units, including supervisory agencies, testing agencies, industry associations, and production companies. "But we didn't give it to us," said the insider of the stainless steel branch.

According to the draft, according to the actual use of stainless steel utensil containers and food contact, the revised standard cancels the relevant regulations for stainless steel models, and only specifies that austenitic stainless steels with good corrosion resistance should be used for food containers. Austenitic, ferritic, stainless steel, and ferritic stainless steels; and martensite stainless steels with high hardness and poor corrosion resistance can be used for tableware and food processing equipment that are exposed to food for a short time.

"What is the better corrosion resistance? It depends on who is better than that. If the ratio is worse, of course it is better. This is tantamount to giving the industry a poor quality stainless steel. The new standard should also be The use of stainless steel material is strictly regulated, not ambiguous," said a domestic stainless steel authoritative expert told this newspaper.

It is worth noting that in the revised version of the feedback, Chaoan Stainless Steel Industry Association and Chaozhou Meixing Stainless Steel Industrial Co., Ltd. and other units proposed that because the standard does not mention GB/T3280 (which belongs to the metallurgical industry standard), Without reference to this document, it is recommended to delete the "GB/T3280 stainless steel cold-rolled steel sheet" in the section. The Shanghai Food and Drug Administration, responsible for drafting, adopted this proposal.

Complaints from the European Union have accused the outsiders of excessive metals such as manganese and nickel. Supor said: “The domestic standard only detects five physical and chemical indicators (lead, chromium, nickel, cadmium, and arsenic), and does not detect manganese. Testing."

In fact, the international standards for manganese in food containers are stringent testing standards. In November last year, the Ministry of Health released a letter on 38 public opinions on “Food Containers for Stainless Steel Food Containers” and other opinions. It has clearly stated: “The National Inspection and Quarantine Department has received the EU's early warning notice for stainless steel food containers, reflecting There are quality problems in China's export of stainless steel food containers and utensils, mainly due to excessive discharge of heavy metals. According to relevant information disclosed in the letter, the main quality problems are: nickel, chromium, manganese, zinc, iron and other metals in metal products. The amount of migration (ie, precipitation) exceeded the standard.

"This is a very strong evidence that the international test not only detects manganese, but also that some countries have detected the amount of iron released," said the expert from the above-mentioned stainless steel branch.

It is worth noting that although relevant departments have realized that metals such as manganese are harmful to the human body and they are also aware that manganese metal is present in some domestic stainless steel food containers and kitchen utensils, the revised version of the 88 standard was not proposed in the last year. The detection requirements, but evaded this issue.

In fact, the 88 standard and the 92 standard have corresponding regulations, such as chromium content of 18% to 19%, nickel content of 8% to 10.5%. "If you follow this standard, the manganese content is less than 2%, because the stainless steel produced according to this standard will not rust, so the precipitation of nickel and manganese is very small." The stainless steel branch emphasized by the above experts.

When manganese is used instead of nickel, stainless steel “rusts” and the chromium oxide film on the stainless steel surface is destroyed, and metals such as manganese and nickel are easily precipitated.

The above-mentioned experts from the stainless steel branch told the newspaper, “I once asked a testing agency in Shanxi whether it can detect manganese in stainless steel. They clearly stated that because there is no relevant standard and there is no detection method, it cannot be detected.”

“In fact, the detection of manganese in the world is very mature. We should also test the physicochemical indicators of manganese in stainless steel food containers,” said the expert.
