When a food sample comes into equilibrium with the atmosphere surrounding it, the water activity in the food sample becomes equal to the relative humidity of the atmosphere surrounding it. Once this equilibrium is reached, the food sample neither gains nor loses moisture over time.  3, record 1, English, - equilibrium%20relative%20humidity

Puisque le degré d'humidité d'équilibre des semences est fonction de leur teneur en huile, la meilleure mesure correspondant à la norme relative au séchage est l'humidité relative à l'équilibre (HRE).

The term indoor relative humidity is sometimes used to specify the relative humidity which outside air will have when heated to a given room temperature, such as 72 °F, without addition of moisture.

The corresponding ratios of specific humidity or of mixing ratio give approximations of sufficient accuracy for many purposes in meteorology. The relative humidity is usually expressed in per cent, and can be computed from psychometric data.
