Code identifying the broad category to which a measurement applies
Code identifying a specific product or process characteristic to which a measurement applies
The value of the measurement
R03050608: At least one of MEA-03, MEA-05, MEA-06 or MEA-08 is required
Code specifying the units in which a value is being expressed, or manner in which a measurement has been taken
Power to which a unit is raised
If C001-02 is not used, its value is to be interpreted as 1.
Value to be used as a multiplier to obtain a new value
If C001-03 is not used, its value is to be interpreted as 1.
Code specifying the units in which a value is being expressed, or manner in which a measurement has been taken
Power to which a unit is raised
If C001-05 is not used, its value is to be interpreted as 1.
Value to be used as a multiplier to obtain a new value
If C001-06 is not used, its value is to be interpreted as 1.
Code specifying the units in which a value is being expressed, or manner in which a measurement has been taken
Power to which a unit is raised
If C001-08 is not used, its value is to be interpreted as 1.
Value to be used as a multiplier to obtain a new value
If C001-09 is not used, its value is to be interpreted as 1.
Code specifying the units in which a value is being expressed, or manner in which a measurement has been taken
Power to which a unit is raised
If C001-11 is not used, its value is to be interpreted as 1.
Value to be used as a multiplier to obtain a new value
If C001-12 is not used, its value is to be interpreted as 1.
Code specifying the units in which a value is being expressed, or manner in which a measurement has been taken
Power to which a unit is raised
If C001-14 is not used, its value is to be interpreted as 1.
Value to be used as a multiplier to obtain a new value
If C001-15 is not used, its value is to be interpreted as 1.
The value specifying the minimum of the measurement range
L050412: If MEA-05 is present, then at least one of MEA-04 or MEA-12 is required
When citing dimensional tolerances, any measurement requiring a sign (+ or -), or any measurement where a positive (+) value cannot be assumed, use MEA05 as the negative (-) value and MEA06 as the positive (+) value.
The value specifying the maximum of the measurement range
L060412: If MEA-06 is present, then at least one of MEA-04 or MEA-12 is required
Code indicating the benchmark of, qualify or further define a measurement value
L07030506: If MEA-07 is present, then at least one of MEA-03, MEA-05 or MEA-06 is required
Code indicating an attribute response when a numeric measurement value cannot be determined
E0803: Only one of MEA-08 or MEA-03 may be present
Code indicating the product surface, layer or position that is being described
Code indicating the method or device used to record the measurement
Code identifying a specific industry code list
P1112: If either MEA-11 or MEA-12 is present, then the other is required
MEA11 is the external code list for the unit of measure.
Code indicating a code from a specific industry code list
MEA12 defines the unit of measure for MEA03, MEA05, and MEA06 from an external code list.
