BIS Certification for Insulated Flask for Domestic Use | IS 17790:2022 | BIS Licence

Introduction

BIS Certification for Insulated Flask for Domestic Use is required under the applicable Indian Standard and Quality Control Order framework for products covered by IS 17790:2022.

IS 17790:2022 is titled “Insulated Flask for Domestic Use — Specification.” BIS describes the standard as covering minimum requirements for domestic insulated stainless-steel flasks used for storing and maintaining the temperature of hot and cold liquids intended for drinking.

The product is included under the Insulated Flask, Bottles and Containers for Domestic Use (Quality Control) Order, 2023, and BIS currently lists IS 17790:2022 under the ISI Mark Scheme / Scheme-I.

Manufacturers need to demonstrate conformity with the applicable requirements through the prescribed BIS certification process, including product testing, documentation, manufacturing controls and other applicable assessment requirements.

About Insulated Flask for Domestic Use

An insulated flask is a reusable container designed to maintain the temperature of liquids for an extended period.

It can be used for:

Drinking water
Hot beverages
Cold beverages
Tea
Coffee
Other suitable drinking liquids

IS 17790:2022 specifically addresses domestic insulated stainless-steel flasks used for maintaining the temperature of hot and cold liquids for drinking purposes.

The standard focuses not only on thermal performance but also on construction, material, safety, leakage, impact resistance, stability, workmanship and other relevant characteristics.

What is BIS Certification?

BIS Certification is a conformity assessment mechanism administered by the Bureau of Indian Standards (BIS).

Incomplete documentation
Inadequate testing arrangements
Failed heat retention test
Failed cold retention test
Leakage failure
Impact test failure
Incorrect capacity
Material non-conformity
Coating failure
BPA-related non-compliance
Poor welding quality
Stopper/O-ring/washer issues
Inadequate quality-control records
Calibration problems
Incorrect marking
Factory not prepared for inspection
Failure to close observations

BIS Certification Cost

There is no single fixed BIS Certification cost applicable to every insulated flask manufacturer.

The overall cost may depend upon:

BIS application charges
Product testing
Number of product variants
Factory inspection
Testing laboratory
Sample requirements
Documentation
Retesting, if required
Consultancy charges
Other applicable BIS fees

BIS's LIMS currently displays laboratory-specific testing charges for IS 17790:2022, and these vary by laboratory and scope.

Therefore, a manufacturer should obtain a product-specific quotation rather than relying on a generic online figure.

BIS Certification Timeline

The actual timeline depends on:

Documentation readiness
Sample availability
Laboratory schedule
Test results
BIS application scrutiny
Factory inspection
Observation closure

A fixed timeline should therefore not be promised without reviewing the manufacturer's product and factory status.
