The BIS certification for Stainless Steel Vacuum Bottles as per IS 17526:2021 is a mandatory certification ensuring that stainless steel vacuum flasks meet stringent quality, safety, and performance standards before being sold in the Indian market. Stainless steel vacuum bottles, commonly used to maintain the temperature of hot or cold liquids, must conform to the Bureau of Indian Standards (BIS) regulations under the Quality Control Order (QCO). This certification assures compliance with critical parameters such as thermal insulation efficiency, material quality, leakage resistance, impact durability, and food safety standards. Both domestically manufactured and imported stainless steel vacuum flasks with or without cups are required to obtain the BIS ISI mark before sale, guaranteeing consumers receive products that are hygienic, durable, and reliable. The IS 17526:2021 standard focuses on rigorous testing protocols including thermal retention tests for hot and cold beverages, tightness and leakage tests, stainless steel grade verification, toxicity and odor assessments, as well as evaluating the finish and construction quality of the vacuum bottles.
