**Executive Summary**
This notification issued by the Bureau of Indian Standards (BIS) on March 23, 2026, announces the establishment of 11 new and revised Indian Standards effective from March 20, 2026. The document specifies a transition period where older versions of these standards will remain in force concurrently until their final withdrawal date of September 20, 2026. These updates cover diverse sectors, including blockchain technology, wind energy, nuclear facilities, and communication equipment.
**Key Points / Main Content**
* **Regulatory Basis:** The standards are established in accordance with Sub-rule (1) of Rule (15) of the Bureau of Indian Standards Rules, 2018.
* **Transition Policy:** Established standards (listed in column 2 of the schedule) remain in force concurrently with the standards to be withdrawn (listed in column 4) until the specified withdrawal date.
**Information Technology and Documentation**
* **Blockchain:** Establishment of IS/ISO/TR 6039: 2023 regarding identifiers for subjects and objects in the design of blockchain systems.
* **Record Management:** Revision of IS 15994 (Part 2) regarding metadata for managing records, focusing on conceptual and implementation issues.
* **Library Standards:** Second revision of IS 15996: 2026 regarding library performance indicators.
**Energy and Nuclear Facilities**
* **Wind Energy Generation:** Establishment of multiple parts of the IS/IEC 61400 series, covering design requirements for fixed offshore wind turbines (Part 3-1), turbine blades (Part 5), and tower/foundation design (Part 6).
* **Nuclear Power Plants:** Second revision of IS 14481 (Part 1) concerning instrumentation systems important to safety and radiation monitoring for accident and post-accident conditions.
**Precision Instruments and Communication**
* **Communication Equipment:** First revision of specifications for megaphones (IS 7136) and C-Band parabolic dish antennas (IS 14230).
* **Measurement Tools:** First revision of IS 9558 for PTFE (Teflon) piston depth gauges.
* **Geospatial Data:** Establishment of IS 19583: 2026 regarding data acquisition and accuracy assessment for orthoimagery.
**Impact Analysis**
**Manufacturers and Industrial Producers**
**Impact**
Manufacturers of megaphones, depth gauges, antennas, and wind turbine components are affected by updated technical specifications and design requirements.
**Action Required**
Must update production processes and quality control protocols to align with the 2026 revisions before the September 20, 2026, deadline.
**Energy Sector Operators (Wind and Nuclear)**
**Impact**
Organizations operating wind farms and nuclear facilities face new safety, monitoring, and structural design requirements.
**Action Required**
Engineering teams must review and implement the new standards for offshore turbine designs, turbine blades, and radiation monitoring instrumentation.
**Information Technology and Records Management Professionals**
**Impact**
The establishment of specific standards for blockchain identifiers and metadata management provides a new standardized framework for system design and record-keeping.
**Action Required**
Systems architects and data managers should adopt the IS/ISO/TR 6039 and IS 15994 (Part 2) standards to ensure interoperability and compliance in digital documentation.
**Testing and Certification Bodies**
**Impact**
Laboratories and certification agencies must update their testing parameters to reflect the revised standards for the 11 categories mentioned.
