Accreditation: Official third-party certification of the competence of a conformity assessment Authority to conduct a specific conformity assessment activity.
Electricity Meters: A device that measures the electrical energy consumed in an electrical circuit. 
Smart Meters: Devices that measure the amount of consumption, save these measurements in a storage unit built into the Meter and can send the measurement result to the Supplier.
Gas Meter: A device designed to measure, store, and display the amount of fuel gas (volume or mass) passing through it.
Water Meters: A device designed to measure, store and display the volume of water passing through a measuring conductor under the Meter measuring conditions.
Heat Meter: A device designed to measure the thermal energy given off in a heat exchange circuit by a fluid called the heat carrier fluid. The Heat Meter is either integrated device or a device composed of sub-assemblies: a Flow Sensor, a dual Temperature Sensor, a computer, or a set of them.
Measuring Devices Confirmation: Conduct a conformity assessment that results in the installation of a confirmation Mark and/or the issuance of a confirmation certificate.
Calibration: The processes that are conducted to define the efficiency and accuracy of Measuring Devices and devices.
Maximum Permissible Error (MPE): The nonintentional Maximum Error of the Measuring Device specified in this Resolution, not to be exceeded.
Label Card: Card that shows the name and address of the Manufacturer of the Measuring Device or the address of the Supplier, the serial number of the Measuring Device, its type or model, its function, characteristics, classification, method of use, capacity or load, Scale, year of manufacture, and any other obligatory basic information.
Type Approval: Resolution issued, based on the type assessment report, certifying that this type of Measuring Device meets its legal Requirements, and accordingly issues a Type Approval Certificate.
Conformity Assessment: Any Activity used directly or indirectly to confirm that the good, product, material, or service meets the relevant technical Requirements.
Conformity Certificate:  A Certificate issued by the Ministry, which confirms the conformity of the Product or any batch thereof to the requirements of the Approved Standard Specifications.
Emirates Conformity Assessment Scheme (ECAS): A Scheme issued by the Ministry, for confirming whether the Product meets the requirements specified in the approved Standard Specifications, directly or indirectly, through specific procedures conducted by the Ministry, such as examination, testing, calibration, inspection or granting the Conformity Certificates.
Metrological Marks: Marks affixed to a legal Measuring Device to indicate whether it meets the requirements for it in accordance with applicable legislation, including the confirmation Mark, the rejection mark, the type approval mark, the protection mark, and the reservation mark, or the reservation of the Measuring Device.
Confirmation Mark: A mark affixed to a Measuring Device clearly certifying that confirmation of the Measuring Device has been carried out and its Conformity with legal Requirements.
Inspection Batch: The quantity of Measuring Devices (or parts thereof) subject to test or inspection.
Acceptance of Inspection Batch: The maximum number of non-conforming samples in accordance with the sampling instructions shall be allowed to accept the Inspection Batch.
Rejection of Inspection Batch: The minimum number of non-conforming samples in accordance with the Sampling Tables will result in the rejection of the Inspection Batch.
Approved Standard Specifications: The standard specifications approved by the Ministry, which are referred as UAE Standard Specifications and shall be abbreviated as (UAE.S).
Measured Quantity: The specific quantity to be measured.
Operational Circumstances: 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 Measuring Device to perform the work for which it was designed under normal conditions.
Interference: It is an influential quantity whose value falls within the limits required by specific requirements but falls outside the operating conditions of the Measuring Device. The influential quantity is considered interference if the operating conditions of the device are not specified.
Critical Change Value: It is the value at which a change in the measurement result is considered to affect the accuracy of the measurement and is specified for each type of Consumer Meter in its Annexes. 
Climatic Conditions: It is the specific weather and environmental conditions that a Measuring Device can withstand.
Sub-assemblies: Physical parts that each operate independently and form a Measuring Device when connected to other compatible sub-assemblies, or to a compatible Measuring Device. 
Mode of Use: The Measuring Device is put to the end user for use for the first time for its own purposes.
Manufacturer: The natural or legal person who manufactures a Measuring Device, markets it under his name or trademark or puts it to use for his own purposes.
Supplier: Anyone whose activity has an impact on the characteristics of consumer meters, including the Manufacturer, importer, carrier, assembler, agent, warehouse, or any major or subsidiary distributor or any legal representative who is responsible for the import, installation, and operation of the Consumer Meters subject to the provisions of this Resolution, and who carries out his activity through a licensed company or individual establishment in the State in accordance with the relevant legislation.
