English term or phrase: evaporation rate
Lo siguiente es un método de enayo para determinar la "evaporation rate" de un solvente. No sé si corresponde "velocidad / razón / índice de evaporación" u otra cosa:

"Use tared 1-ounce shallow salve cans with covers and do weighing on an analytical balance. Weigh 1 gram of test solvent in one can and 1 gram of n-butyl acetate in another can. Place the containers in a draft-free area, preferably with controlled temperature and humidity. Remove the covers and reweigh at intervals until the samples have completely evaporated. The time in minutes for n-butyl acetate divided by the time for the test solvent is the **evaporation rate**. It may be advisable to change the size of the samples for solvents that are quite fast or quite slow. A very slow tail of a few percent may be disregarded."

Mil gracias desde ya.

índice de evaporación/tasa de evaporación


Explanation:
Según contexto, "evaporation rate" se refiere a una cantidad sin dimensión o adimensional producto del cuociente entre el tiempo de evaporación de un solvente y el tiempo de evaporación del solvente de prueba. Por lo tanto, correspondería más bien a un índice o tasa de evaporación.
