National Food Safety Standard - Metal Materials and Products for Food Contact1 ScopeThis Standard is applicable to metal materials and products for food contact.2 Terms and Definitions2.1 Metal Materials and Products for Food Contact Under normal conditions of use, various metal (including various metal plating and alloys) materials and products that are expected to come into contact with or have come into contact with food. Hereinafter referred to as “metal materials and products”. 2.2 Metal Plating A metal coating formed on the food-contact surface of a solid material or product through various plating techniques. 2.3 Base Material A material constituting the matrix of metal materials and products, excluding surface coatings and metal plating. 2.4 Alloy Elements When smelting metals, one or multiple metallic or non-metallic elements that are intentionally added to achieve certain property requirements (such as. tensile strength, hardness, wear resistance, corrosion resistance and electrical conductivity, etc.). Metallic alloy elements, such as. aluminum, copper, chromium, manganese, molybdenum, nickel, zinc, tin and cobalt, etc.; non-metallic alloy elements, such as. carbon and silicon, etc. 2.5 Impurity Elements Unintentionally added elements remaining in a metal.3 Basic RequirementsThe metal materials and products shall comply with the stipulations of GB 4806.1.4 Technical Requirements4.1 Requirements for Raw Materials 4.1.1 The metal base material, metal plating and welding materials used by metal materials and products shall not cause harm to human health. 4.1.2 The manufacturing enterprises of the metal materials and products shall control the substances used and remaining during metal surface treatment (such as. acid pickling, oxidation, phosphating, polishing and anti-rust oiling, etc.), so that the amount of migration into food complies with the requirements of GB 4806.1. 4.1.3 The metal base material and metal plating used for food contact shall not use lead, cadmium, arsenic, mercury, antimony, beryllium and lithium as alloy elements, and the impurity element content shall satisfy the requirements of Table 1. 4.1.4 The composition of metal base materials and metal plating shall be consistent with the corresponding composition of the product’s labeled composition or designation. 4.1.5 If it is necessary to determine the composition content of metal materials or perform designation identification through inspection, the inspection methods that comply with the relevant requirements of GB 4806.1 shall be adopted for determination. 4.2 Sensory Requirements The sensory requirements shall comply with the stipulations of Table 2. 4.3 Physical and Chemical Indicators 4.3.1 Impurity element migration indicators The migration indicators of impurity elements shall comply with the stipulations of Table 3. 4.3.2 Alloy element migration indicators The migration indicators of alloy elements shall comply with the stipulations of Table 4. 4.4 Other Technical Requirements 4.4.1 The metal materials and products for food contact that use coatings, inks and (or) adhesives, etc. shall also comply with the stipulations of corresponding national food safety standards for coatings, inks and (or) adhesives, etc. 4.4.2 The amount of tin in tinned thin steel plate containers that migrates into food shall satisfy the requirements of GB 2762 and other relevant national food safety standards.5 Others5.1 Migration Test 5.1.1 The migration test shall be carried out in accordance with the stipulations of GB 31604.1 and GB 5009.156.Except for the special stipulations in Appendix A. 5.1.2 The metal materials and products expected to be repeatedly used shall be subject to three migration tests in accordance with the requirements of GB 31604.1.Specifically speaking, the compliance of stainless-steel materials and products is determined based on the determination results of the third test. If the amount of migration measured in the first test does not exceed the limit, and there is evidence to prove that the amount of migration measured in subsequent tests will not increase, there is no need to conduct the subsequent tests. Metal materials and products made of other textures will be deemed disqualified if any one of the three migration test results exceeds the limit. 5.2 Label Identification 5.2.1 The label identification shall comply with the stipulations of GB 4806.1. 5.2.2 Metal base materials shall also be clearly marked with their material type and material composition. If the composition is consistent with the corresponding composition of the national standard designation of China, it can also be represented by the national standard designation of China or a unified digital code, for example, “stainless-steel 06Cr19Ni10” or “stainless-steel S30408”, “aluminum alloy 3004”. 5.2.3 If the food-contact surface is covered with a metal plating, the material of the plating shall also be marked, such as. “chromium plating” and “zinc-nickel alloy plating”, etc. When there is more than one layer of metal plating, in accordance with the sequence of bottom plating - middle plating - surface plating (the plating on the food-contact surface), mark the metal composition of each layer, and use slashes to separate them, for example “copper / nickel / chromium plating”.Appendix ASpecial Requirements for Migration Test A.1 Food Simulants In accordance with the types of food that metal materials and products are expected to come into contact with, and Table A.1, select food simulants. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
