Annex (1) Essential Requirements − Introduction: The legal measuring instrument must possess a high level of metrological protection, ensuring confidence in any party affected by the measurement results the instrument generates. It must also be designed and manufactured to a high quality, particularly regarding measurement techniques and data security. This Annex outlines the essential requirements that a legal measuring instrument must meet, in addition to the specific requirements for each legal measuring instrument detailed in Annex
(2) of this Resolution.
− 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.
1. Allowable Error: 1-1 The allowable error in a legal measuring instrument must not exceed the maximum allowable error specified for the instrument under normal operating conditions and in the absence of disturbances, unless otherwise stated. 1-2 In the presence of disturbance, and under the rated operating conditions of the instrument, the performance requirements for the legal measuring instrument must meet those outlined in the specific annex for that instrument, as detailed in Annex (2) of this Resolution. For legal measuring instruments intended to be used in a specific, continuous electromagnetic field, the instrument must maintain its metrological properties within the maximum allowable error limits. 1-3 The manufacturer must specify the climatic environments, mechanical, and electromagnetic conditions under which the legal measuring instrument is intended to operate, along with the power supply and other influence quantities that may affect measurement accuracy, considering the specific requirements for the legal measuring instrument. 1-3-1 Climatic environment:
The manufacturer must specify the maximum and minimum temperature values as outlined in Table (1) of this Annex unless otherwise stated in the specific requirements for the legal measuring instrument. The manufacturer must also indicate whether the instrument is designed for operation in humid or dry conditions, or in open or closed environments, stating any changes in reading when the ambient temperature changes.
Table (1) Temperature Limits ( °C ) Max Limits 30 40 55 70 Min Limits 5 -10 -25 -40
1-3-2 Mechanical Environment:
a. The mechanical environment is classified into the following categories:
