How Long Can Stainless Steel Thermos Be Kept Warm?

When you buy a stainless steel vacuum flask, you always hear the business say "very thermal insulation", "good thermal insulation effect", "XX hours of thermal insulation" and so on. Is there a national or international thermal insulation standard for stainless steel vacuum flask?

This standard is there, but this standard is not the same due to differences in regions, nations, and countries. Taking Europe as an example, usually the pursuit of heat preservation of water cups is not too high, as long as 6-8 hours of heat preservation is enough, but the Chinese market is different. Consumers are more concerned about the heat preservation of water cups, and prefer to keep warm for 8 hours. Above, try as long as possible. According to the requirements of the international standard for the insulation time of the thermos, after the 96℃ water cup is kept for 6 hours, the water temperature in the cup can reach about 56℃, which is a qualified thermos cup.
