What are the international certification standards for stainless steel thermos?
As a common daily necessity, the quality and safety of stainless steel thermos have attracted the attention of consumers around the world. Here are some international certification standards that ensure the quality and safety of stainless steel thermos:

1. China National Standard (GB)

GB/T 29606-2013: specifies the terms and definitions, product classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of stainless steel vacuum flasks (bottles, pots).

2. European Union Standard (EN)

EN 12546-1:2000: Specifications for vacuum vessels, thermos flasks and thermos pots for household insulation containers involving materials and articles in contact with food.

EN 12546-2:2000: Specifications for household insulation containers involving materials and articles in contact with food.

3. U.S. Food and Drug Administration (FDA)
FDA 177.1520, FDA 177.1210 and GRAS: In the U.S. market, food contact products such as stainless steel thermos cups must meet the relevant FDA standards.

4. German LFGB standard
LFGB: In the EU market, especially Germany, stainless steel thermos cups need to undergo LFGB testing to ensure that they meet the safety standards for food contact materials.

5. International food contact material standards
GB 4806.9-2016: “National Food Safety Standard Metal Materials and Products for Food Contact” stipulates the use of austenitic stainless steel, duplex stainless steel, ferritic stainless steel and other materials for food containers.

6. Other related standards
GB/T 40355-2021: Applicable to daily stainless steel vacuum insulation containers for contact with food, which stipulates the terms and definitions, classification and specifications, requirements, test methods, inspection rules, markings, etc. of stainless steel vacuum insulation containers.
These standards cover the material safety, thermal insulation performance, impact resistance, sealing performance and other aspects of stainless steel thermos, ensuring the competitiveness of the product in the international market and the safety of consumers. When producing and exporting stainless steel thermos, companies must follow these international certification standards to meet the requirements of different markets.

How to ensure that stainless steel thermos meet international certification standards?
To ensure that stainless steel thermos meet international certification standards, a series of quality control measures and testing processes need to be followed. The following are the key steps and standards:

1. Material safety
The inner liner and accessories of the stainless steel thermos cup should be made of 12Cr18Ni9 (304), 06Cr19Ni10 (316) stainless steel, or other stainless steel materials with corrosion resistance not lower than the above specified grades
The outer shell material should be austenitic stainless steel
Must comply with the “National Food Safety Standard General Safety Requirements for Food Contact Materials and Products” (GB 4806.1-2016) standard, which has 53 specific national food safety standards and different regulations for different materials

2. Insulation performance
According to GB/T 29606-2013 “Stainless Steel Vacuum Cup”, the insulation performance level of the thermos cup is divided into five levels, with level I being the highest and level V being the lowest. The test method is to fill the thermos cup with water above 96℃, close the original cover (plug), and measure the temperature of the water in the thermos cup after 6 hours to evaluate the insulation performance

3. Impact resistance test
The thermos cup should be able to withstand the impact of free fall from a height of 1 meter without breaking, which is in accordance with the requirements of national standards

4. Sealing performance test
Fill the thermos cup with 50% of the volume of hot water above 90℃, seal it with the original cover (plug), and swing it up and down 10 times at a frequency of 1 time/second and an amplitude of 500mm to check for water leakage

5. Inspection of sealing parts and hot water odor
It is necessary to ensure that accessories such as sealing rings and straws use food-grade silicone and have no odor

6. Compliance with international standards
The EU market requires compliance with CE certification, including product performance analysis, thermal insulation performance testing, cold insulation performance testing, etc.
The US market requires compliance with FDA standards to ensure the material safety of stainless steel thermos cups

7. Compliance Marking and Labeling
After obtaining CE certification, you need to affix the CE mark to the thermos product and ensure that the outer packaging and label of the product comply with relevant regulations and standards

8. Selection of testing laboratory
The test items involved in CE certification need to be carried out in an accredited laboratory. Ensure that the selected testing laboratory meets the relevant requirements and can provide accurate and reliable test results

Through the above measures, it can be ensured that the stainless steel thermos meets international certification standards during the production process, ensure the quality and safety of the product, and meet the import requirements of different markets.
