Absorbent Cotton Gauze refers to medical textiles, which are extensively used during wound dressing. Other areas of application include operations and other medical procedures that require absorption of blood and sterility near the surgical area. The Cotton Gauze is made from quality cotton yarns knitted together to create a lightweight fabric to facilitate effective absorption of bodily fluids and air circulation near the affected area.
Adherence to IS 758:2023 provides a necessary benchmark to assess the quality and safety of medical textiles. In addition to testing for its absorbency capacity, pH value, whiteness index, presence of residual impurities, and sterility, BIS certification includes testing for consistency of the fabric used and its tensile strength. It is important to make sure that all these parameters comply with high medical standards before allowing the use of such a biomedical material in hospitals.
What is IS 758: 2023?
This is the Indian Standard for Absorbent Cotton Gauze used in medical and surgical applications. It specifies the quality, absorbency and hygiene requirements to ensure safe and effective use in the healthcare sector. As per the BIS (Bureau of Indian Standards), these Cotton Gauze are:
- Evaluated for sterility and cleanliness
- Tested for strength
- Checked for absorbency and purity
- Assessed for weave construction
Eligibility Criteria for Surgical Gauze BIS License
BIS authorisation under IS 758: 2023 is required for businesses involved in manufacturing, importing, or supplying medical textiles in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if Wound Dressing Gauze are covered under QCO.
- Foreign Manufacturers - Need certification to export the product to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified Medical Absorbent Gauze.
Testing and Inspection Requirements
Absorbent cotton gauze used for clinical purposes is required to meet certain standards of quality as stated in IS 758: 2023. This standard provides for proper absorbency, cleanliness, strength, and suitability of the product for application in the healthcare industry.

| pH Value Test | pH level of aqueous extract | Ensures the gauze is safe and non-irritating for skin contact |
| Scouring Loss Test | Removal of impurities and processing residues | Ensures proper cleaning and processing of gauze fabric |
| Optical Whitener Test | Presence of optical whitening agents | Ensures absence of prohibited whitening substances |
| Microbial/Bioburden Test | Cleanliness and microbial contamination level | Ensures hygiene and suitability for medical applications |
Step-by-Step BIS Approval Process for Surgical Gauze
The BIS Authorisation process ensures that the Medical Absorbent Cotton Gauze meet the required safety standards. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for absorbency, fabric quality, tensile strength, cleanliness and uniformity of weave.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials visit the manufacturing facility to evaluate production processes, safety measures, and the quality control system.
- Grant of BIS License: After all compliance requirements are satisfactorily met, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Following approval, the manufacturer is authorized to use the ISI Mark on the product along with a valid CM/L number, confirming that the product meets BIS standards.
