## Report on Amendments to Indian Standards - Automotive and Electrical **1. Executive Summary:** This report analyzes a notification from the Bureau of Indian Standards (BIS) establishing amendments to four existing Indian Standards (IS) related to automotive vehicles and electrical equipment. The amendments address braking systems for two and three-wheeled vehicles, AC static transformer operated watthour meters, safety belt anchorages for automotive vehicles, and braking provisions for M and N category vehicles. The core purpose of these amendments is to update and refine existing standards, likely in response to technological advancements, safety considerations, or harmonization with international practices. The amendments will remain in force until November 4, 2025. **2. Introduction:** This report provides an overview and analysis of a notification published by the Bureau of Indian Standards (BIS) concerning amendments to existing Indian Standards. The analysis is based solely on the provided text of the notification. The purpose is to inform affected industries about the nature, scope, and implications of these changes. **3. Policy Overview:** This notification concerns amendments to existing Indian Standards. The core objective, inferred from the text, is to update and improve existing standards to ensure safety, performance, and conformity with current technologies or best practices in the automotive and electrical sectors. **4. Background and Rationale:** This notification pertains to Amendments, not a new policy. The likely reason for these specific amendments is to address evolving requirements and ensure the continued relevance and effectiveness of the original standards. It can be inferred that technological advancements, new safety concerns, or the need for greater precision or harmonization with international standards have necessitated these revisions. **5. Key Provisions / Changes:** This section focuses on the changes introduced by the amendment text. The notification details amendments to the following standards: * **IS 14664 : 2010 (Amendment No. 6):** Pertains to "Automotive Vehicles Performance Requirements and Testing Procedure for Braking System of Two and Three Wheeled Motor Vehicles First Revision". The amendment likely modifies the braking system performance requirements or testing procedures for these vehicles. While the specific changes are not detailed in the provided text, it can be inferred that they may relate to improved braking efficiency, enhanced safety, or adaptation to new technologies. * **IS 14697 : 2021 (Amendment No. 2):** Relates to "a.c. Static Transformer Operated Watthour Meters Class 0.2 S and 0.5 S and VarHour Meters Class 0.2 S, 0.5 S and 1S Specification First Revision". The amendment likely refines the specifications for these meters. It is inferred that these refinements pertain to accuracy, reliability, or compatibility with advanced grid infrastructure. * **IS 15139 : 2002 (Amendment No. 3):** Concerns "Automotive Vehicles Safety Belt Anchorages Specification". The amendment likely introduces changes to the specifications for safety belt anchorages. The inferred impact could be improving passenger safety during collisions. * **IS 15986 : 2015 (Amendment No. 3):** Relates to "Automotive Vehicles Uniform Provisions Concerning the Approval of Vehicles of Categories M and N 1 1 with Regard to Braking". The amendment likely affects the approval process for braking systems in M and N category vehicles (likely passenger vehicles and goods vehicles). The inferred impact would likely include changes to braking requirements. In all cases, the *specific* changes are not detailed in the provided text, but the amendments will remain in force until November 4, 2025. **6. Target Audience and Stakeholders:** Based on the text, the directly affected audience and stakeholders include: * Automotive manufacturers (two-wheeled, three-wheeled, M & N category vehicles) * Manufacturers of safety belt anchorages * Manufacturers of a.c. static transformer operated watthour meters * Testing and certification bodies involved in assessing compliance with these standards * Regulatory bodies overseeing automotive safety and electrical metering. **7. Implementation Aspects (Inferred):** * **Responsible Agency/Bodies:** The Bureau of Indian Standards (BIS) is the responsible agency for implementing and enforcing these amendments. * **Timelines:** The amendments are effective from May 5, 2025, and will remain in force until November 4, 2025. This suggests a six-month window for compliance with the revised standards. * The industry must update their products and processes to align with the amended standards before November 4, 2025, to maintain compliance. **8. Expected Outcomes / Impact of Changes:** The likely intended outcomes of these amendments are: * Improved safety performance of two and three-wheeled vehicles through enhanced braking systems. * Greater accuracy and reliability of electricity metering through refined watthour meter specifications. * Enhanced passenger safety in automotive vehicles due to improved safety belt anchorage standards. * Harmonization of braking provisions for M and N category vehicles with international standards. **9. Conclusion:** The BIS notification outlines important amendments to Indian Standards related to the automotive and electrical industries. While the specific details of the amendments are not provided in the text, the notification signals a commitment to continuously improving standards to ensure safety, performance, and technological relevance. Affected industries must familiarize themselves with the revised standards and implement the necessary changes to ensure compliance. The significance of these changes lies in their potential to enhance product quality, improve safety, and promote consumer confidence.
