EXCEL Template -Calibration of Compression Machine Uncertainty Budget - for Absolute Beginners

Compression Machine Force Calibration Uncertainty Budget — Complete Excel Template (CPGL-CAL-009)

Ready-to-use ISO 17025 Excel workbook for compression testing machine force calibration uncertainty analysis. Built for concrete cube testing machines, universal testing machines (UTM), and hydraulic compression testers used in construction materials testing.

What You Get:

• Pre-built uncertainty budget with all Type A and Type B components for force measurement
• Automated Welch-Satterthwaite formula calculating effective degrees of freedom
• Built-in 30-entry Student-t lookup table for coverage factor (k) at 95.45% confidence
• Sensitivity coefficients (ci = ∂F/∂xi) auto-calculated for each uncertainty source
• YES/NO toggle switches to include or exclude individual uncertainty contributors
• Measurement results with auto-calculated expanded uncertainty and pass/fail assessment

Key Features:

• Compliant with ISO/IEC 17025:2017 and ISO GUM (JCGM 100:2008)
• Covers force transducer reference uncertainty, machine repeatability, resolution, hysteresis, creep, zero drift, and environmental factors
• Automatic unit conversion and sensitivity coefficient propagation
• Professional certificate-ready output with traceability documentation
• Works in Excel and Google Sheets — no macros required

Designed for: Calibration laboratories, construction testing labs, quality managers, metrology technicians, and ISO 17025 accreditation bodies preparing for ILAC, A2LA, NABL, or UKAS assessments.

Pairs with: CPGL-CAL-009 Compression Machine Force Calibration Procedure (sold separately or as a bundle).
