The world today
Legal metrology is taught from documents: the Recommendation as required reading, the test procedures as photocopies, and, if the institution is well equipped, a borrowed instrument for one afternoon a semester. Students learn that a load cell has an accuracy class, but never watch a verdict computed against one. The field’s deepest ideas , traceability, uncertainty, conformity assessment, stay abstract because there is nothing to practice on.
What changes
The classroom is the system itself. The SMI Simulation is a full-fidelity
teaching instrument: a virtual load cell (and belt scale, and gas
meter) with realistic, configurable physics, temperature cycles leave
residuals, creep and hysteresis behave the way the Recommendation
describes. Students run the actual certification workflow against it:
apply, test, evaluate, issue, with the real app, the real verdict
engine, the real certificate chain. When something is unprovable, the
system says indeterminate, and the class learns why that honesty is
the foundation of metrological trust.
What it looks like in practice
The curriculum is layered, stop wherever your course stops:
- Tier 0, the tour: fifteen minutes; what a SMART Recommendation is and why it exists.
- Tier 1, the reader: navigate a modelled Recommendation; requirements, tests, forms, provenance.
- Tier 2, the operator: certify the simulated load cell end to end, role by role.
- Tier 3, the author: model a toy standard in Primmel; the linter grades it; the coverage calculus checks it.
- Tier 4, the platform: the kernel, the runtime, the twin interfaces, internals, with proofs.
The proof
Every tier ends in a checkable artifact, not a quiz, but a thing the student produced that the system itself can verify.
Your next step
Open the classroom, or jump straight to the demo manual and certify your first load cell this afternoon.
