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, issued by the Bureau of Indian Standards (BIS) on March 24, 2026, announces the establishment of nine new and revised Indian Standards effective from March 23, 2026. The document specifies that older versions of these standards will remain in force concurrently until their final withdrawal on September 23, 2026. Stakeholders must transition to the updated specifications within this six-month period.
**Key Points / Main Content**
**Battery and Container Specifications**
* **IS 1146 : 2026:** Establishes the third revision for rubber and plastic containers used in lead-acid storage batteries. This replaces the second revision (IS 1146 – 1981).
**Electrical Conductors and Motors**
* **IS 7391 (Part 1 & 2) : 2026:** Introduces the first revision for cotton-covered copper conductors, covering both round and rectangular variations.
* **IS 15429 : 2026:** Updates the code of practice for the storage, installation, and maintenance of d.c. motors (First Revision).
**Switchgear and Power Installations**
* **IS/IEC 60947-4-1 : 2023:** Notifies the third revision for low-voltage switchgear and controlgear, specifically electromechanical contactors and motor-starters.
* **IS/IEC TS 61936-0 & IS/IEC 61936-2 : 2023:** Establishes requirements for power installations exceeding 1 kV a.c. and 1.5 kV d.c., focusing on design, erection principles, and safety.
**Protective Devices and Statistical Methods**
* **IS 16463 (Part 22) : 2026:** Establishes selection and application principles for low-voltage surge protective devices connected to telecommunications and signaling networks.
* **IS 16179 : 2026 (ISO 10576 : 2022):** Provides updated guidelines for the evaluation of conformity with specified requirements using statistical methods.
**Impact Analysis**
**Manufacturers and Industrial Producers**
**Impact**
Manufacturers of lead-acid batteries, copper conductors, d.c. motors, and switchgear are directly affected by the revised specifications. Their current products must eventually comply with the 2026 versions to maintain valid certification.
**Action Required**
Producers must review the updated standards and align their manufacturing processes, materials, and quality control systems with the new requirements before the September 23, 2026, withdrawal date of previous versions.
**Testing and Certification Bodies**
**Impact**
Laboratories and certification agencies must update their testing protocols to reflect the new revisions (e.g., the transition from IS 1146:1981 to IS 1146:2026).
**Action Required**
Update internal standard operating procedures (SOPs), calibrate equipment for new parameters where necessary, and begin testing products against the 2026 standards.
**Regulatory and Safety Authorities**
**Impact**
Authorities overseeing electrical installations and telecommunications networks must recognize the updated safety and design principles for high-voltage installations and surge protective devices.
**Action Required**
Incorporate the revised standards (such as IS/IEC 61936-2:2023) into safety inspections and compliance audits for power and telecom infrastructure.
