ISI / BIS Certification is mandatory for

Domestic Stainless steel vacuum flask/bottle

IS Standard : IS 17526:2021

Home vacuum flasks and bottles made of stainless steel are becoming commonplace in homes all over the world because of their remarkable insulating qualities and capacity to maintain a temperature for prolonged periods of time. Most of the time, these bottles are made from premium stainless steel, which guarantees their longevity and protects the integrity of the liquids within by resisting rust and odors. Domestic stainless steel vacuum flasks are notable for having two walls with a vacuum-sealed layer sandwiched in between. With this design, heat transmission is effectively reduced, preventing heat from hot drinks from escaping or heat from the outside from entering cold drinks. Because of this, these flasks are perfect for keeping drinks at the perfect temperature, whether it a steaming hot cup of coffee in the morning while driving to a cool, refreshing iced drink on a hot summer day.

The Indian Standard IS 17526:2021 lays out specifications for household vacuum flasks or bottles made of stainless steel. In order to ensure that the beverages held in vacuum flasks are safe to consume, producers must develop vacuum flasks that satisfy strict quality and safety standards, which is made possible by compliance with IS 17526:2021. Following these guidelines guarantees that the vacuum flasks are made to efficiently maintain the intended temperature, protecting the beverages' freshness and quality. Manufacturers who follow these guidelines lower their risk of legal problems and liabilities by ensuring that their goods meet food safety rules.

Note: It is mandatory for manufacturers of vacuum flasks or bottles made of stainless steel meant for home use to get the ISI Mark Certification.

In order to maintain the freshness of beverages and keep them hot or cold, ISI certification is an essential guarantee of the quality, safety, and functionality of these common home goods. It means that these items have passed extensive testing and meet the strict standards established by the BIS, which are designed to assess their functionality, robustness, and safety. By meeting the required criteria, this certification guarantees that the materials used to manufacture the flasks or bottles are free of hazardous contaminants that may seep into the beverages they are storing.


About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.
