SMART Recommendations · Demo

The live models

R 60 is the reference SMART model — the only official pilot. The other three are demo models, built to exercise the method on other instrument families. Each renders from its model: the terminology, the requirements, the conformance tests, the report forms, and the certification workflow that runs on them.

The official pilot

• OIML R 60:2021 — Load cells

  The reference SMART model — the only official pilot. Classification, MPE envelopes, the conformance tests, the R 60-3 forms.

Demo models

• OIML R 91:2025 — Traffic speed meters

  Demo model. Speed measurement: the operational envelope and its disturbance tests.

• OIML R 129:2020 — Multi-dimensional measuring instruments

  Demo model. Dimensional metrology with multi-axis measurands.

• OIML R 144:2013 — Gas analytical systems

  Demo model. CO and NOx in stationary source emissions: per-channel measurands and the sampling-line subsystem.

The per-Recommendation pages are served by the OIML SMART platform (the private application builds them from the same models). The authoring documentation for building one yourself lives in the docs section.
