Mass/Weights Calibration Toolkit (ISO 17025) — Procedure + Uncertainty Budget Excel — CPGL-CAL-007

Complete Mass/Weights Calibration Toolkit for ISO/IEC 17025 Laboratories

Save weeks of development time with this ready-to-use calibration toolkit. Fully aligned with ISO/IEC 17025:2017, ISO GUM (JCGM 100:2008), and EURAMET cg-18.

This bundle includes:

1. Calibration Procedure (Word .docx) — CPGL-CAL-007

• Comprehensive mass/weights verification procedure
• 10 uncertainty sources with sensitivity coefficients (ci)
• Welch-Satterthwaite formula for effective degrees of freedom
• Student-t coverage factor lookup (not assumed k=2)
• Ready for your lab logo and document control

2. Uncertainty Budget Excel Template (.xlsx)

• Multi-point calibration worksheet (repeatability as standard deviation per EURAMET cg-18)
• YES/NO applicability toggles for each uncertainty source
• Built-in quality checks (combined uncertainty validation, k-factor bounds)
• Student-t VLOOKUP table (1-30 degrees of freedom)
• Assumptions and Guidelines reference tab
• 10 expanded uncertainty sources per calibration point
• Print-ready A4 layout

Uncertainty sources: Repeatability, resolution, reference standard, drift, buoyancy correction, eccentricity, magnetism, convection effects, contamination, rounding

Who is this for? Calibration labs preparing for or maintaining ISO 17025 accreditation, calibration managers, and technical signatories.

Developed by an ISO 17025 approved signatory. Saves 40-80 hours vs building from scratch. Instant download.
