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) announces the establishment of eight new Indian Standards under the IS 19751 series concerning railway infrastructure. Established on June 23, 2026, these standards provide comprehensive specifications and testing methods for rail fastening systems. No existing standards are scheduled for withdrawal in conjunction with this notification.
**Key Points / Main Content**
**Establishment of IS 19751 Series**
* **Purpose:** To define vocabulary and standardized testing procedures for "Railway Infrastructure — Rail Fastening Systems."
* **Effective Date:** All listed standards were officially established on June 23, 2026.
* **International Alignment:** The new standards are largely based on or equivalent to ISO 22074 series (varying from 2020 to 2022 versions).
**Specific Standards and Test Methods**
* **IS 19751 (Part 1): 2026:** Establishes the formal vocabulary for rail fastening systems.
* **IS 19751 (Part 2): 2026:** Outlines the test method for longitudinal rail restraint.
* **IS 19751 (Part 3): 2026:** Specifies the proof load test method for pull-out resistance.
* **IS 19751 (Part 4): 2026:** Details test methods for determining resistance to repeated loading.
* **IS 19751 (Part 5): 2026:** Provides the test method for measuring electrical resistance.
* **IS 19751 (Part 6): 2026:** Defines test methods for resistance to severe environmental conditions.
* **IS 19751 (Part 7): 2026:** Covers testing for clamping force and uplift stiffness.
* **IS 19751 (Part 8): 2026:** Establishes the test method for vertical stiffness.
**Impact Analysis**
**Manufacturers and Suppliers of Rail Fastening Systems**
**Impact**
Manufacturers must now adhere to the newly established IS 19751 standards for quality control and technical specifications. The standards introduce specific testing protocols for durability, environmental resistance, and mechanical performance.
**Action Required**
Entities must update their manufacturing processes and quality assurance protocols to comply with the established standards and ensure their products meet the specific testing criteria (Parts 2 through 8) as of June 23, 2026.
**Railway Infrastructure Authorities and Developers**
**Impact**
Procurement and safety benchmarks for railway infrastructure are now governed by these updated Indian Standards.
**Action Required**
Authorities should update their technical tender specifications and project requirements to reference the IS 19751:2026 series for all new railway infrastructure developments involving rail fastening systems.
**Testing and Certification Bodies**
**Impact**
Laboratories and certification agencies must recognize these new standards as the official benchmarks for testing rail fastening components.
**Action Required**
Testing facilities must calibrate their equipment and update their accreditation scopes to perform the specific tests (e.g., pull-out resistance, electrical resistance, and vertical stiffness) as defined in the IS 19751 series.
