The Bureau of Indian Standards (BIS) has released a comprehensive notification announcing the establishment of multiple new Indian Standards across diverse technical fields, including homoeopathy, cybersecurity and privacy, digital audio systems, and wind energy.
The notification, issued under Rule 15(1) of the BIS Rules, 2018, also outlines the withdrawal timelines for superseded standards, ensuring an orderly transition for manufacturers, IT service providers, engineering units, and energy sector entities.
All newly established standards take effect from 30 October 2025, while older versions—where applicable—will remain valid until 30 April 2026, after which they stand withdrawn.
The table below consolidates the key details from the official BIS notification:

🔍 Sector-wise Breakdown
1️⃣ Homoeopathy Sector
Three new standards strengthen pharmaceutical-grade material requirements used in homoeopathic formulations. These standards focus on:
- Mother tincture preparation (Percolation method)
- Plant extract (Holarrhena antidysenterica) specifications
- Sugar of milk quality norms
These updates enhance quality, purity, and consistency across homoeopathic medicines.
2️⃣ Cybersecurity, Information Security & Privacy
Four standards have been issued to align India’s digital security ecosystem with global ISO/IEC frameworks:
- Revised IS/ISO/IEC 27019 sets upgraded cybersecurity controls for the energy utility sector.
- New standards establish guidelines for:
- Network virtualization security (27033-7)
- IoT security & privacy (27403)
- Privacy engineering (POMME, 27561)
These are crucial for critical infrastructure protection, smart homes, and privacy-by-design implementation.
3️⃣ Digital Audio Interface Updates
Three updated standards harmonize Indian regulations with IEC specifications for:
- Digital audio interfaces for consumer applications
- Professional audio metadata, subcode, and electrical parameters
Technical upgrades ensure better interoperability, performance stability, and safety for consumer and pro-audio systems.
4️⃣ Wind Energy Standards Strengthened
Two significant standards boost the regulatory framework for wind power plants and turbine safety:
- Measurement and assessment of electrical characteristics of wind farms
- Guidelines for marking and lighting of wind turbines, enhancing operational safety and grid integration
These updates support India’s renewable energy expansion goals.
📌 Overall Impact
The BIS notification brings multiple sectoral benefits:
- Harmonisation with international standards for global trade compatibility
- Improved cybersecurity assurance for utilities, IoT, and digital networks
- Stronger consumer safety measures across audio and renewable energy technologies
- Enhanced regulatory clarity for manufacturers, laboratories, integrators, and energy operators
- Smooth transition timeline through simultaneous validity until April 2026
The harmonised standards framework ensures India’s technical regulations stay aligned with evolving global best practices.
