Arbitrary reciproc threshold mass concentration (arb.recip.threshold mass c.)
Abbreviation |
Arb.recip.threshold mass c. | ||
---|---|---|---|
Definition in words |
Volume of system 1 divided by arbitrary threshold mass of component B | ||
Definition by equation |
Note: kprocedure is a constant defined by the measurement procedure (there is an approximately proportionality to a kind-of-quantity from the International System of Quantities). |

Unit |
International unit (IU) or procedure defined unit (p.d.u.) (non-SI units) | ||
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. If the unit is an International Unit (IU), an international certified reference material (e.g. WHO reference material) is specified in the specification to the kind-of-property. If there exist no international certified reference material, the laboratory can specify the unit at the placeholder, procedure defined unit. |
