- bis certifications for Stainless Steel Vacuum Flasks create immediate consumer trust and retailer acceptance in India.
- Timely bis certifications for Stainless Steel Vacuum Flasks cut customs delays and enable faster marketplace onboarding.
- IS 17526:2021 defines the safety, durability, and thermal performance standards for Stainless Steel Vacuum Flasks in India.
Introduction
In fact, the Bureau of Indian Standards (BIS) has made mandatory compliance to IS_17526:2021 for Domestic Stainless Steel Vacuum Flasks/Bottles in order to ensure product safety, quality, and reliability. This compliance falls under the Quality Control Amendment Order, 2024, which entitles most of the manufacturers and importers to obtain BIS certification for having such products in their range. In this post, we shall talk about the certification process, scheme of inspection and testing, relevant test equipment, and important features of this standard.
Key Highlights of IS 17526:2021
The standard IS 17526:2021 sets guidelines for the safety, durability, and performance of domestic stainless steel vacuum flasks/bottles. Below are its key highlights:
| Feature | Description |
| Material Requirement | Stainless steel (grade as per standard) |
| Thermal Insulation | Minimum heat retention as specified |
| Leakage Test | No leakage under specified conditions |
| Corrosion Resistance | Passes corrosion resistance tests |
| Impact Resistance | The flask should not break or deform under impact |
| Marking & Labeling | Must include ISI mark and manufacturer details |
| Hygienic Properties | Free from harmful coatings and contaminants |
Process of BIS Certification for Domestic Stainless Steel Vacuum Flasks/Bottles
Step 1: Identify the Required Certification Scheme
For domestic stainless steel vacuum flasks and bottles, BIS certification has been granted under the ISI Mark Scheme. This means that the manufacturer needs to comply with IS 17526:2021 and undergo factory inspection and product testing.
Step 2: Prepare Necessary Documents
Manufacturers must submit the following:
- Business registration documents (Company Incorporation Certificate, GST, etc.)
- Manufacturing unit details (address proof, factory layout, list of machinery, etc.)
- Product test reports from a BIS-approved lab
- Quality control measures (Standard Operating Procedures, raw material details, in-house testing facilities)
- Authorized signatory details along with the authorization letter
- Undertaking of compliance with BIS standards
Step 3: Product Testing in BIS-Approved Lab
The manufacturer has to send the sample of the stainless steel vacuum flask/bottle to a BIS-recognized laboratory.
The lab tests the product as per IS 17526:2021, verifying for thermal insulation, the composition of materials, prevention of leakage, and durability.
Once the testing has been done, detailed testing reports are given.
Step 4: Factory Inspection by BIS Officials
Post-application scrutiny, the BIS inspectors carry out a visit to the manufacturing unit to assess the processes of production of various raw materials, testing facilities, and systems that assure quality control.
This inspection process verifies and affirms manufacturers’ claims concerning their ability to manufacture consistent quality products according to BIS standards.
Step 5: Grant of a BIS License
Following the satisfactory evaluation of the factory inspection and the test reports carried out according to BIS standards, the license is granted, and an ISI Mark Certificate is issued to the manufacturer authorizing the product to bear the BIS ISI mark.
The certificate is valid for one year and can be renewed based on compliance.
Scheme of Inspection and Testing (SIT) for IS 17526:2021
The Scheme of Inspection and Testing (SIT) ensures stringent BIS Compliance for the bottles. Important parameters are:
- Raw Material Verification: Checking grade and quality of stainless steel.
- Heat Retention Test: Testing the flask for temperature retention with time.
- Leakage Test: Testing vacuum sealing and leak proofing ability.
- Impact and Drop Test: Testing behavior against falls and impacts.
- Corrosion Resistance Test: Testing to ensure that the flask remains rust-free in humid conditions.
- Marking and Labeling Compliance: Checking the presence of the ISI Mark and relevant labeling particulars.
List of Test Equipment Required for IS 17526:2021 Compliance
These are the equipment for an in-house lab and third party testing that a manufacturer should have:
- Temperature Retention Test Setup- For determining the heat holding capacity of flasks.
- Vacuum Leakage Testing Machine- For detecting air leaks in a vacuum flask.
- Corrosion Resistance Test Chamber- To check against rust and environmental factors.
- Impact Test Equipment- Testing the flask durability when accidentally it drops.
- Marking and Labeling Inspection Tools- For checking that ISI mark regulations are followed.
- Hygienic Testing Equipment- For ensuring no harmful coating is deposited on a flask or residue left.
Importance of BIS Certification for Stainless Steel Vacuum Flasks/Bottles
- Legal Compliance: The Quality Control Amendment Order 2024 has made BIS certification mandatory for manufacturers and importers.
- Consumer safety: It is qualified to state that hygiene and quality standards have been met by the product.
- Market credibility: A BIS-certified product gains trust and wider market acceptance.
- Avoid penalties: There will be legal action as well as a penalty for selling non-compliant products.
- Global recognition: A BIS-certified product has better chances for international trade.
