Classifies the volatility of a liquid according to the official thresholds of Table 8 of the INRS method.

Usage

inrs_liquid_volatility_pressure(vapour_pressure)

Arguments

vapour_pressure

Numeric. Vapour pressure at working temperature, in kPa.

Value

Character scalar ("1" if Pv < 0.5 kPa, "2" if 0.5 <= Pv < 25 kPa, "3" if Pv >= 25 kPa).

Examples

inrs_liquid_volatility_pressure(15)
#> [1] "2"
