by | Feb 4, 2020 | List of kinds-of-property, Kind-of-quantity

Expiry

Definition in words

 The end of the period for which something is valid.

Systematic terms

 Expiry of component B in system 1

Result type

 Ordinal scale
  • Value set is ranked accoding to magnitude
  • The value set and the limit of the value set are defined by the laboratory
  • The value set can be either numerical values or words.

Example 1

Value set={none < some < high < very high}

Example 2

Value set={low < normal< high }

Example 3

Value set={0 < 1 < 2}

Example 4

Value set={negative < positive}

Example 5

Value set={+ < ++ < +++}
  • Algebraic operations are not allowed (Ref. 2, 1.26)
  • Possible comparison of value sets  (a<b, a=b or a>b).

Unit

 None

Special rule(s) in the NPU syntax

“Procedure” is stated in the specification to the kind-of-property in the NPU definition.

“Procedure” indicates that the measurement procedure must be stated somewhere else than the NPU code and there may be difficulties in comparing values for the same NPU code.
