Built-in CMC and uncertainty budgets give a capability claim its numerical basis.
Create scope entries and contributor budgets, calculate supported endpoints, and publish a reusable technical curve. Keep numerical support separate from accreditation approval.

Built-in CMC budget
Inspect the contributors supporting the low and high endpoints of a capability budget.Standard by MetraSlate: Metrology Edition demonstration data · Captured 21 October 2026. Confirm the screens and workflows in your pilot configuration.
Standard brings CMC budget calculation, scope entries and measurement uncertainty into the calibration workflow. A technical manager can maintain the evidence behind a claimed range while technicians and reviewers inspect the basis used for individual measurements.
The work begins with a defined reference standard and measurement function. The laboratory records the source or measure role, range, unit, optional frequency band, and claimed gain, offset and coverage factor. This gives the capability a numerical definition that can be checked against its supporting budget.
The contributor budget explains the capability.
A CMC budget retains contributor values at a low and a high point. Sensitivity and the selected distribution convert those inputs into standard uncertainty contributions. Supported inputs include normal-expanded, rectangular, triangular, U-shaped and standard-deviation values. An expanded-uncertainty input retains the coverage factor at which it was stated.
Standard combines the uncorrelated contributions by root-sum-square and calculates effective degrees of freedom. The scope-budget calculation can use a fixed coverage factor or its Student-t coverage basis. It applies one coverage factor across the two endpoints and rounds the expanded endpoint uncertainties upward to the supported publication precision before fitting the curve.
The claim and its supporting calculation remain connected.
A capability claim can become unsupported when a contributor changes. Standard distinguishes a claim that has no computed budget from one supported by the calculation and one that undercuts its supporting uncertainty. A refusal identifies the numerical disagreement so the laboratory can review the claim or its contributors.
Publishing places the fitted curve into the reference standard’s specification catalog. The curve retains its coverage and budget relationship. This is a technical publication; it is not an accrediting body’s approval of the laboratory’s scope.
The retained uncertainty budget

A built-in CMC calculator makes the arithmetic visible.
The engineering-calculator library also includes a CMC Uncertainty Budget tool. Its survey, low-point budget, high-point budget and equation views let the user examine contributor values, sensitivity, distributions, degrees of freedom, endpoint uncertainty and the fitted gain and offset.
Calculator drafts and saved results are stored locally in the user's browser. A calculator study is useful for examining the numbers; the scope-entry budget and controlled publication keep the laboratory's reusable capability definition attached to its reference standard.
Capability work continues into measurement review.
A published reference-standard curve supplies a contribution to later point evaluation. The calibration record then combines the actual attributed standards with the DUT-resolution contribution and the selected measurement policy. This connects capability preparation to the uncertainty reported for the work.
The laboratory can revisit contributors and ranges as its standards and methods change, while reviewing completed results against their retained calculation evidence. Budget authoring supports preparation and maintenance of scope evidence; it does not automatically submit an accrediting body's complete scope document.

In everyday use
What your team can do.
Follow the record, the decision and the person responsible for the next step.
The scope entry identifies what is claimed.
Reference-standard equipment, function, role, range, units and frequency qualification keep the claim attached to the capability it describes.
Each contributor retains its assumptions.
Low and high values, sensitivity, distribution, input coverage, degrees of freedom and exclusion state explain how the budget was assembled.
The endpoints support a reusable curve.
Standard calculates the endpoint budgets and fits a gain-plus-offset uncertainty curve for the declared band.
The claim can be checked against its support.
Claim states distinguish an uncomputed budget, a claim supported by its budget and a claim that is tighter than the configured evidence supports.
Publication creates a controlled specification release.
The published curve carries its budget reference and coverage factor. Republishing replaces that budget's previous curve within one release.
The laboratory keeps responsibility for accreditation.
Standard organizes and calculates the supporting evidence. The laboratory and its accrediting body approve the scope and accreditation.
