Arbitrary conductivity (arb.conductivity)
Abbreviation |
Arb.conductivity | ||
---|---|---|---|
Definition in words |
Arbitrary conductivity of component B in system 1 Note: Electrical conductivity is the reciprocal of resistivity (Ref 1) |
||
Definition by equation |
Note 1: 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. |

Abbreviated form with a result | NPU21552 Sweat(spec.)—Sweat; arb.conductivity(proc.) = 25 arbitrary unit | |
Written expression | The arbitrary conductivity of Sweat from Mr. Smith’s right arm is [25] arbitrary unit. The measurement is performed according to a procedure defined by the laboratory, | |

Notes
|
“Arbitrary unit” was chosen by a local laboratory as a proprietary measurement unit and not an accepted international unit. | |
