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

Hello everyone, "Dong Dong Talks About Cups" is here. In the last article, due to the length of the article, we shared with you half of the content about FDA testing standards. http://www.umbottle.com/ProductsDetail-VB-10489.htmlToday we will continue to share the rest with you. Thank you for your continued participation.

Chemical stability test: Test the stability of the thermos bottle under different pH conditions to ensure that no harmful substances are released due to contact with acidic or alkaline liquids.

Printing ink safety test: If there are printed words or patterns on the thermos cup, the printing ink safety test is also required to ensure that the ink will not cause harm to human health. http://www.umbottle.com/ProductsDetail-VB-10489.htmlSince the printing ink does not come into contact with drinking water, the testing standard is relatively low, but it also includes the testing of paints and other coatings. Some water cups are designed with paints and other coatings in direct contact with the mouth when people drink water, so it is also necessary to test whether harmful substances will be released.

Whether printed patterns or various paints and other coatings on stainless steel water bottles (stainless steel thermos bottles, etc.) can pass the dishwasher test is not currently tested by the FDA. http://www.umbottle.com/ProductsDetail-VB-10489.htmlThis is usually the result of self-testing by the manufacturer after receiving clear requirements from the purchaser.

To determine whether a stainless steel thermos cup has passed FDA testing and certification, consumers can make judgments in the following ways:

Check the product label: Certified thermos bottles usually have "FDA certified" or "FDA compliant" clearly marked on the product label or packaging. http://www.umbottle.com/ProductsDetail-VB-10489.htmlConsumers can check the product label to find out whether the product has passed FDA testing and certification.

Understand the manufacturer's information: FDA-certified products usually have the manufacturer's information marked on the product packaging. http://www.umbottle.com/ProductsDetail-VB-10489.htmlConsumers can judge whether the product is credible by understanding the manufacturer's background and reputation.

Check certification documents: Consumers can also ask manufacturers or third-party agencies to provide FDA testing and certification documents for products to confirm that the product has passed relevant testing and certification.
