What is Mass Calibration?
Mass Calibration is the process of verifying and adjusting the accuracy of standard weights (also called calibration masses) used for testing and calibrating weighing instruments such as balances and scales. These masses are compared against national or international reference standards to ensure traceable, precise weight values.
Why is Mass Calibration Important?
Mass Calibration is essential in laboratories, manufacturing, pharmaceuticals, food production, and any environment where weighing precision is critical. Errors in mass can lead to non-compliance, product inconsistencies, financial loss, or safety issues.
- Ensures traceable and accurate weight standards
- Meets ISO/IEC 17025, OIML, ASTM, and NIST standards
- Supports legal-for-trade and quality assurance requirements
- Improves consistency in measurement and production
- Reduces risk of weighing errors and failed audits
What Equipment Needs Mass Calibration?
Mass Calibration is needed across a wide variety of instruments, such as:
- OIML Class E1, E2, F1, F2, M1, M2 and M3 Weights
- ASTM Class 0-7 Weights
- Precision Laboratory Masses
- Industrial Test Weights
- Calibration Weight Sets
- Stainless Steel Masses
- Brass Masses
- Nickel Masses
- Chrome Masses
- Cast Iron Masses
Who Needs Mass Calibration?
Mass Calibration is vital for any organisation using weights for calibration, testing, or legal-for-trade measurement requires mass calibration. This includes:
- Calibration and Metrology Laboratories – Using weights as standards for other calibrations
- Pharmaceutical & Medical Device Manufacturers – Where mass accuracy is essential for dosage and formulation
- Food and Beverage Industry – Legal-for-trade weighing and portion control
- Retail and Trade Businesses – Where mass affects pricing (e.g., butchers, grocers, fuel stations)
- Manufacturing & Engineering – For component weighing, batching, and quality control
- Aerospace & Automotive – For parts verification and material testing
- Educational and Research Labs – Using precision weights for experiments and data accuracy
- Weights and Measures Inspectors – Verifying public and trade devices
How Often Should It Be Calibrated?
- Every 12 months – Industry standard for most commercial and laboratory applications
- Every 6 months or quarterly – In highly regulated industries (e.g. pharmaceutical, medical, or legal metrology)
- After damage, contamination, or heavy use
- Before regulatory audits or certifications
Mass calibration frequency should follow ISO 17025, ISO 9001, and GMP/GLP requirements, as well as trading standards.
