characterization factor

[‚kar·ik·tə·rə′zā·shən ′fak·tər]
(chemical engineering)
A number which expresses the variations in physical properties with change in character of the paraffinic stock; ranges from 12.5 for paraffinic stocks to 10.0 for the highly aromatic stocks. Also known as Watson factor.

In this framework, toxicity-related impacts on human health are described by a matrix CF [member of] [R.sup.hxc] of characterization factors (disability-adjusted life years, DALY/d per [kg.sub.emitted]/d) expressing impacts on humans via health end points h for emissions into environmental compartments c:
We captured these summary recommendations from the task force process to propose guidance for efforts to develop a globally harmonized framework and characterization factors for incorporating human toxicity impacts.
The inputs of this network are American Petroleum Institute (API) gravity, kinematic viscosity at 37.8[degrees]C, characterization factor, and steam distillation factor, while the output is distillate recovery.
