What tests do stainless steel thermos bottles need to undergo to pass FDA testing? (I)

Hello everyone, "Dong Dong Talks About Cups" is here. The article shared today and the previous article about FDA testing standards were written by the editor on the morning of September 15, 2024, so there may be some repetition in the content of the article, please forgive me. http://www.umbottle.com/ProductsDetail-VB-10489.htmlToday, the editor will talk about what specific items of testing are required for stainless steel water cups (stainless steel thermos cups, etc.) to pass FDA testing?

During my many years in the industry, I have experienced countless products passing FDA inspections. http://www.umbottle.com/ProductsDetail-VB-10489.htmlSince I have experienced this so many times, I would like to share with you what I have experienced in the inspection of stainless steel water cups (stainless steel thermos cups, etc.) products. I hope it will be of some help to you.

In order to pass FDA testing and certification, stainless steel water cups (stainless steel thermos cups, etc.) need to undergo multiple tests, including but not limited to the following aspects:

Material analysis: test whether all the water-contact materials in the stainless steel finished water cups meet the FDA food release material standards to ensure that they do not contain any harmful substances, such as lead, mercury, cadmium, etc. Test whether these materials are radioactive. http://www.umbottle.com/ProductsDetail-VB-10489.htmlHere I would like to share my personal experience. In a 2022 inspection, the silicone sealing ring in the inspected product failed because the radiation exceeded the standard. Later, it was found that it was a problem with the materials used in the silicone sealing ring produced by the factory.

Thermal stability test: Test the stability of the cup body in a high temperature environment, requiring the thermos cup not to release harmful substances during the heating or insulation process.

Sealing test: Test the sealing performance of the thermos cup to ensure that the lid and mouth of the cup are tightly sealed to prevent liquid leakage.

Thermal insulation effect test: Test the thermal insulation effect of the thermos cup, measure the temperature change of the liquid in the cup within a certain period of time, and ensure that the cup has good thermal insulation performance.
