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
