Kind-of-quantity of component B divided by volume of system 1

Note: “Concentration” indicates that the system is a liquid system

• 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. 3, 1.26)
• Possible comparison of value sets  (a<b, a=b or a>b).

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

“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.

“?” (placeholder for result) is omitted.
