E54 Dimension
Scope note: This class comprises quantifiable properties that are measured by some calibrated means and can be approximated by numerical values.
An instance of E54 Dimension is regarded as the true quantity, independent from its numerical approximation, e.g. in inches or in cm. The properties of the class E54 Dimension allow for expressing the numerical approximation. It is recommended to record all numerical approximations of instances of E54 Dimension as intervals of indeterminacy. Numerical approximations in archaic instances of E58 Measurement Unit used in historical records should be preserved. Equivalents corresponding to current knowledge should be recorded as additional instances of E54 Dimension as appropriate. Examples:
- currency: £26.00
- length: 3.9-4.1 cm
- diameter 26 mm
- weight 150 lbs
- density: 0.85 gm/cc
- luminescence: 56 ISO lumens
- tin content: 0.46 %
- taille au garot: 5 hands
- calibrated C14 date: 2460-2720 years, etc
Spectrum 3.1 Dimension Definitions
Dimension
Definition: The aspect of a part or component of an object being measured.
How to record: Use a single term, without punctuation or capitalization. Maintain a list of standard terms. The organization should agree a standard method of measuring different types of object.
Examples: height; width; depth; diameter; weight; circumference; radius; trade; size
Use: As many times as required for an object.
Dimension measured part
Definition: The part of an object measured.
How to record: Use a single term, without punctuation or capitalization. Maintain a list of standard terms.
Examples: base; frame; mount
Use: Record once only for a Dimension.
Dimension measurement unit
Definition: The unit of measurement used when measuring a Dimension.
How to record: Use a single term, without punctuation or capitalization, or use a standard abbreviation. Maintain a list of standard terms. The organization should decide which are the standard units for different dimensions and types of object.
Examples: m; mm; inches; troy; grains
Use: Record once only for a Dimension.
Dimension value
Definition: The numeric value of the measurement of a Dimension.
How to record: A number, without punctuation other than a decimal point where required. The value should be to the nearest point of detail dictated by the type of object and the needs of the procedure and the organization.
Examples: 987; 0.234
Use: Record once only for a Dimension.
Dimension value qualifier
Definition: The measurement of statistical deviation given for a dimension. If left blank, the assumption is that the Dimension accuracy recorded is thought to be correct. Do not use capitalization or punctuation.
How to record: Use the standard statistical notation
Examples: + or - 150; approximate; to the nearest cm
Use: Record once only for the Dimension recorded if there is any uncertainty.
