Seamless Global Compliance: NMi Now Offers ANSI C12.32 Certification for DC Electricity Meters 

As the energy landscape evolves, direct current (DC) electricity metering is becoming increasingly critical across industries—from renewable energy and energy storage to EV charging infrastructure and industrial power systems. With the expansion of DC applications, manufacturers should ensure that their meters meet European and North American standards to achieve efficient global market access. 

To support this growing need, NMi has expanded its testing services to include certification to ANSI C12.32 [2021], the key standard for revenue-grade DC meters in North America. This addition complements our existing IEC 62053-41 [2021] and EN 50470-4 [2023] services, positioning NMi as a single-source certification provider for manufacturers targeting these key markets. 

Why ANSI C12.32 Matters for DC Metering

As DC power systems gain traction, ensuring accurate and standardized metering is more important than ever. ANSI C12.32 [2021] sets essential performance, accuracy, and environmental requirements for revenue-grade DC electricity meters up to 1,500 V DC, making it a critical certification for manufacturers seeking entry into the North American market. 

For manufacturers, compliance with ANSI C12.32 means ensuring that their meters meet the expectations of North American utilities, regulators, and consumers, which opens the doors to market entry and regulatory approval. 

One Partner for Multi-Market Compliance

Manufacturers designing DC electricity meters face the challenge of ensuring their products comply with multiple regional standards. With different testing and certification requirements in North America and Europe, companies often undergo duplicative testing, extended approval timelines, and increased costs. 

NMi simplifies this process by offering a comprehensive certification pathway covering: 

IEC 62053-41 [2021] – The international standard for static DC meters 

EN 50470-4 [2023] – The European standard for DC metering accuracy and performance 

ANSI C12.32 [2021] – The North American standard for revenue-grade DC meters

By integrating these key standards under one testing partner, NMi provides manufacturers with a unified, efficient, and cost-effective path to global market access. 

Seamless Market Access with NMi:

Achieving global compliance requires more than meeting technical requirements—it demands a strategic certification approach that simplifies regulatory navigation while ensuring product integrity. 

By offering a holistic certification portfolio for DC electricity meters, NMi provides manufacturers with a single-source solution for entering both European and North American markets, eliminating the need for separate testing providers and redundant certification processes. 

The benefits of partnering with NMi for multi-market certification: 

Market access in both North America and Europe with a streamlined certification strategy 

Faster time-to-market by testing for multiple regions simultaneously 

Reduced costs by minimizing redundant testing and approval processes 

Simplified product development by aligning designs with multiple standards from the outset 

Stronger product credibility with certification from a trusted, independent authority

Our ISO 17025 accreditation for ANSI C12.32 is underway, reinforcing the same rigorous standards of quality, independence, and technical excellence as the rest of our certification portfolio. 

With NMi as your testing partner, manufacturers can confidently bring accurate, reliable, and fully compliant meters to the global market—efficiently and cost-effectively. 

Looking Ahead: A Smarter Path to Compliance 

For manufacturers developing new DC electricity meters or adapting existing designs for international certification, NMi now provides a single-source solution for market entry across key regions. 

By integrating ANSI C12.32 certification alongside IEC 62053-41 and EN 50470-4, we help manufacturers navigate complex regulatory landscapes, simplify compliance, and accelerate time-to-market. 

As the demand for DC power metering continues to grow, ensuring products meet the right global standards will be crucial for market success. With NMi as your trusted testing partner, manufacturers can confidently bring best-in-class metering solutions to customers worldwide.
