− Definitions:
1. Measurand: The specific quantity to be measured.
2. Influence quantity: A value that affects the measurement result but is not part of the measurand.
3. Rated Operating Conditions: The sum of the measured value plus the influencing quantity, which together constitute the conditions that shall be maintained during the measurement to enable the Legal Measuring Instrument to perform the work for which it was designed under normal conditions.
4. Disturbance: It is an influential quantity whose value falls within the limits required by specific requirements but falls outside the operating conditions of the Legal Measuring Instrument. The influence quantity shall be considered a disturbance if the operating conditions are not specified for the legal measuring instrument.
5. Critical Change Value: The value at which a change in the measurement result is considered undesirable.
6. Material Measure:
A measuring instrument designed to permanently give or restore specific measurement values, without having a screen or display to show the measurement result.
7. Direct Sale: A commercial transaction is considered a direct sale if:
a. The measurement result is used as the basis for the price paid.
b. One of the parties involved in the transaction is the consumer or another party requiring a similar level of protection.
c. The measurement result is accepted by all parties.
8. Climatic Environments: The climatic conditions under which the legal measuring instrument will be used. This Resolution specifies the range of temperature limits that the legal measuring instrument can withstand.
