1 Scope
This Standard is applicable to metal materials and products for food contact.
2 Terms and Definitions
2.1 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 Requirements
The metal materials and products shall comply with the stipulations of GB 4806.1.
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 Others
5.1 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.

National Food Safety Standard –
Metal Materials and Articles Used in Food-contact
1 Scope
This Standard applies to metal materials and articles used in food-contact.
2 Terms and Definitions
2.1 metal materials and articles used in food-contact
all kinds of metal materials and articles (including all kinds of metal coatings and alloys)
which are expected to be or have been in contact with food, under normal conditions
of use, hereinafter referred to as “metal materials and articles”.
2.2 metal coating
a metal film formed on the surface of all kinds of solid materials or articles by plating
2.3 base material
a material constituting the matrix of metal materials and articles, not including surface
coating or metal coating.
3 Basic Requirements
Metal materials and articles shall meet the specifications of GB 4806.1.
4 Technical Requirements
4.1 Material requirements
4.1.1 Metal base materials, metal coatings and welding materials used to make metal
materials and articles shall not be harmful to human health.
4.1.2 Composition of materials including metal base materials and coatings shall be
consistent with corresponding composition marked or designated for such products.
4.1.3 Main part of stainless steel food containers and tools and equipment for food
production shall be stainless steel material, i.e. austenitic stainless steel, austenite-
ferrite stainless steel and ferritic stainless steel; main part of stainless steel table ware
high temperature sterilization for not more than 2 h,
and storage at room temperature or below room
temperature for more than 30 d)
In contact with food for 3 d or less than 3 d at room
temperature or below room temperature
40°C; test time is specified in Table 3 of GB 31604.1-
In contact with food for 3 d or less than 3 d at room
temperature or below room temperature, and in
contact with hot food occasionally
70°C; test time is specified in Table 3 of GB 31604.1-
After hot filling, store at room temperature for 24 h
or less than 24 h 70°C, 2 h; and then 40°C, 24 h
High temperature contact such as steaming and
boiling, frying and baking (except uncoated iron fry
pans)
Boiling temperature, 2 h
Uncoated iron fry pan Boiling temperature, 1 h
Electric heating food processing equipment and
other electric appliances for food processing
Based on the maximum time and maximum
temperature designated in instruction manual or
used in production and operation, choose test time
and temperature in accordance with Table 3 and
Table 4 of GB 31604.1-2015, but the maximum test
temperature shall not exceed 100°C
A.3 Other requirements
A.3.1 For electric heating food processing equipment and other products, take the
minimum rated volume and its corresponding contact area as the ration of food
simulant volume to sample contact area, if instruction manual has designated rated
volume.
A.3.2 If a product has an adaptive cover, it can be tested based on the sealing
condition during normal use.
A.3.3 When migration test of food simulant needs to be carried out for tin plated or
chromium-plated sheet containers, try to simulate the sealing condition of containers
during normal use; prevent air from getting in containers. Use an empty can sealed by
user if possible; drill a hole at the centre of can cover (bore diameter shall be as small
as possible); use a clean syringe or other utensils deemed appropriate to inject the
food simulant heated to test temperature into the can through the bore, until it is filled.
Use sealing film or appropriate inert plug to seal the hole, to prevent air getting in the
can. Carry out migration test in accordance with the conditions chosen; after the
specified test time, shake the can to mix up the solution in it; open the can cover;
immediately pour the solution in a clean glass or plastic container; and use an
appropriate amount of nitric acid to acidize the solution before carrying out analysis of
the target.
