OIML R 60 • Metrological regulation for load cells

2.5 Documentation

The documentation submitted with the application for type evaluation shall include:

  1. a description of its general principle of measurement;

  2. mechanical drawings (including documents on the load transmission(s) as per Annex E);

  3. electric/electronic diagrams;

  4. installation requirements (physical and electrical) if appropriate;

  5. operating instructions that shall be provided to the user if appropriate;

  6. documents or other evidence to support and demonstrate the manufacturer’s belief that the design and characteristics of the load cell will comply with the requirements of this Recommendation; and

  7. documentation relative to software if appropriate.

If the test laboratory deems this necessary, it can require more detailed documentation; either to be able to study the quality of the instrument, or to be able to fully define the approved type, or both.

If the manufacturer does not prescribe a specific load transmission, it will be the responsibility of the test laboratory to decide what kind of load transmission is to be used for testing (also see Annex E).
