In pursuance of Sub rule 1 of Rule 15 of the Bureau of Indian Standards Rules, 2018, the Bureau of Indian Standards hereby notifies that Indian standards, particulars of which are given in the second column
**Executive Summary**
This notification from the Bureau of Indian Standards (BIS), dated 23rd March 2026, announces the establishment of ten new or revised Indian Standards effective from 20th March 2026. Most revised standards will operate concurrently with older versions until a final withdrawal date of 20th September 2026. The document primarily covers technical specifications for medical instruments, prosthetics, and acoustic calibration.
**Key Points / Main Content**
**ENT Surgical Instruments**
* **Revised Specifications:** New 2026 standards have been established for various ENT instruments, including Chevalier Jackson’s pattern forceps (vocal nodule and general), Irwin Moore's bronchoscopy forceps, cup forceps (straight and upward), and microlaryngeal surgery scissors.
* **New Establishment:** IS 19731: 2026 has been introduced as a new standard for Otology Drills.
* **Withdrawal Timeline:** Previous versions of these surgical instrument standards (ranging from 1977 to 1994) will be withdrawn on 20th September 2026.
**Acoustics and Calibration**
* **Audiometric Equipment:** IS 4755 (Part 1): 2026 (harmonized with ISO 389-1: 2017) is established for "Reference Zero" calibration of pure tone air conduction audiometers.
* **Supersession:** This replaces the 1987 version of IS 4755, with the older version set for withdrawal on 20th September 2026.
**Prosthetics and Biotechnology**
* **Jaipur Foot:** IS 17034: 2026 (First Revision) has been established, superseding the 2018 version.
* **Extracellular Vesicles:** A new standard, IS 19615: 2026, has been established for the characterization of extracellular vesicles.
**Impact Analysis**
**Manufacturers of ENT Instruments and Prosthetics**
**Impact**
Existing products certified under older standards (e.g., IS 8327, IS 8743, IS 17034) will need to meet updated 2026 specifications to remain compliant.
**Action Required**
Manufacturers must update their production and quality control processes to align with the 2026 revisions before the previous standards are withdrawn on 20th September 2026.
**Audiometric Equipment Calibration Services**
**Impact**
The reference levels for calibrating pure tone air conduction audiometers have been updated via IS 4755 (Part 1): 2026.
**Action Required**
Calibration laboratories must transition their procedures and equipment settings to the new "Reference Zero" standards by the September 2026 deadline.
**Biotechnology Research and Characterization Entities**
**Impact**
A formal Indian Standard (IS 19615: 2026) now exists for the characterization of extracellular vesicles.
**Action Required**
Relevant stakeholders should adopt these new guidelines immediately, as there is no prior standard or withdrawal period.
