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: k_{procedure} is a constant defined by the measurement procedure (there is an approximately proportionality to a kindofquantity from the International System of Quantities). 

Systematic terms 
Arbitrary conductivity of component B in system 1  
Result type 
Rational scale 


Unit 
International unit (IU) or procedure defined unit (p.d.u.) (nonSI units).  
Special rule(s) in the NPU syntax 
“Procedure” is stated in the specification to the kindofproperty 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 kindofproperty. If there exist no international certified reference material, the laboratory can specify the unit at the placeholder, procedure defined unit.

Full form with a result  NPU21552 Sweat(specification)—Sweat; arbitrary conductivity(procedure) = 25 arbitrary 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.
