BS EN 62058-21:2010

Overview

BS EN 62058-21:2010 specifies the acceptance inspection requirements for electromechanical meters used in the measurement of active energy. This standard is crucial for ensuring that electricity metering equipment operates accurately and reliably, particularly for meters classified under classes 0.5, 1, and 2, as well as class indexes A and B. The standard aligns with the international IEC 62058-21:2008, ensuring consistency in metrology practices across Europe.

Key Requirements

The standard outlines specific criteria that must be met during the acceptance inspection of electromechanical meters. Key requirements include:

• Accuracy Verification: Meters must demonstrate compliance with specified accuracy classes, ensuring that they measure energy consumption within acceptable limits.
• Functional Testing: All operational features of the meter must be tested to confirm they function correctly under various conditions.
• Environmental Conditions: Meters should be assessed under specified environmental conditions to ensure reliability in diverse settings.
• Calibration Procedures: Detailed calibration procedures must be followed to maintain the integrity of the measurement system.

Implementation Benefits

Adopting BS EN 62058-21:2010 provides several practical benefits for compliance professionals and organisations involved in electricity metering:

• Enhanced Accuracy: By adhering to the standard, organisations can ensure that their metering equipment provides precise measurements, reducing the risk of billing errors.
• Improved Reliability: Regular acceptance inspections as per the standard help maintain the reliability of metering systems, which is essential for operational efficiency.
• Regulatory Compliance: Compliance with this standard aids in meeting national and international regulatory requirements, thus avoiding potential penalties.
• Market Confidence: Demonstrating compliance with recognised standards can enhance customer trust and confidence in the services provided.

Compliance Value

Compliance with BS EN 62058-21:2010 is not merely a regulatory obligation; it is a strategic advantage. The standard facilitates:

• Risk Management: By ensuring that meters are accurately calibrated and functioning correctly, organisations can mitigate risks associated with inaccurate energy billing.
• Quality Assurance: Implementing the standard contributes to a robust quality assurance framework, ensuring that metering equipment meets high-performance standards.
• Cost Efficiency: Accurate metering can lead to better energy management, resulting in cost savings for both providers and consumers.

In conclusion, BS EN 62058-21:2010 serves as a vital framework for the acceptance inspection of electromechanical meters. By adhering to its requirements, organisations can enhance their operational integrity, ensure compliance, and ultimately provide better service to their customers.
