Description

The Role of Legal Metrology in Modern Weighing Inspection Systems


Introduction to Legal Metrology in Industrial Weighing

Legal metrology forms the foundation of trustworthy weighing inspection systems in modern manufacturing and

trade environments. As global supply chains become more complex and regulatory requirements more stringent,

the integration of legal metrology principles into weighing systems has evolved from simple compliance to a

strategic quality assurance imperative.


Core Principles of Legal Metrology in Weighing

1. Metrological Traceability

  • Definition: Unbroken chain of calibrations to national/international standards

  • Implementation:

    • NIST (USA), PTB (Germany), or NIM (China) traceable certification

    • ISO/IEC 17025 accredited calibration procedures

    • Documentation of measurement uncertainty budgets


Industry-Specific Implementations

Pharmaceutical Manufacturing

  • Critical Parameters:

    • USP <41> compliance for balances

    • 21 CFR Part 11 electronic records

    • Measurement uncertainty ≤0.1% of tolerance

  • Validation Protocol:

    • 3-point calibration (min, nominal, max)

    • 99.7% confidence level (3σ)

Retail Weighing Systems

  • Key Requirements:

    • Automatic price calculation verification

    • Zero-tracking within ±0.25e

    • Mandatory sticker printing accuracy

  • Inspection Frequency:

    • Initial verification

    • Annual surveillance

    • 2-year recertification
