Stainless steel material products in direct contact with food, belonging to food contact materials, need to be tested according to the national standard GB4806.9-2016 "Food Safety National Standard Food Contact Metal Materials and Products", the following takes you to understand GB4806.9-2016 food contact stainless steel material testing standards.
Stainless steel, as the name suggests, is a metal steel that will not rust, stainless steel has steel that is resistant to air, steam, water, acid, alkali, salt and other chemical media. Stainless steel is divided into: martensitic steel, ferritic steel, austenitic steel, austenitic -ferritic steel, precipitation hardened stainless steel and so on.
The common 304 stainless steel on the market is widely used, and the 304 stainless steel is an austenitic stainless steel. Especially in food contact materials, 304 stainless steel is used relatively much, but food contact stainless steel is not only 304, as long as it meets the requirements of the national food grade standard GB 4806.9-2016, it can be used as food grade stainless steel. Therefore, if we stainless steel is 201, 316, 401, 420, 430 and other grades, as long as it has passed the requirements of GB 4806.9-2016, it can be used as a food contact material.
Stainless steel food grade testing requirements, the old national standard is based on the standard GB 9684-2011 "stainless steel tableware container health standards" for constraints, after the introduction of the new national standard, stainless steel material testing must comply with GB 4806.9-2016 "food safety national standard food contact metal materials and products", the standard officially began to be implemented on April 19, 2017.
New standard for stainless steel material testing for food contact GB 4806.9-2016 "National Standard for Food Safety Metal Materials and Products for Food Contact" Items are:
Therefore, for stainless steel food grade material products, the testing standards need to be comprehensively and strictly tested in accordance with the requirements of GB 4806.9-2016 "National Food Safety Standards for Metal Materials and Products for Food Contact", and in the testing institutions with the ability to test food contact packaging materials.
