Time-weighted average (TWA) exposure limit is the time-weighted average concentration of a chemical in air for a normal 8-hour work-day and 40-hour workweek to which nearly all workers may be exposed day after day without harmful effects. Time-weighted average means that the average concentration has been calculated using the duration of exposure to different concentrations of the chemical during a specific time period. In this way, higher and lower exposures are averaged over the day or week. 1, record 1, English, - time%2Dweighted%20average%20exposure%20limit

La moyenne pondérée sur le temps (MPT) est la concentration moyenne d'une substance dans l'air sur une période normale de 8 heures de travail par jour ou 40 heures par semaine, à laquelle presque tous les travailleurs peuvent être exposés jour après jour sans subir d'effets nuisibles. "Valeur pondérée sur le temps" veut dire qu'on a établi une valeur moyenne de la concentration en fonction de la durée de l'exposition à différentes concentrations sur une période déterminée. De cette façon, on obtient une moyenne des concentrations élevées et des faibles concentrations rencontrées au cours d'une semaine ou d'une journée. 2, record 1, French, - limite%20d%27exposition%20moyenne%20pond%C3%A9r%C3%A9e%20en%20fonction%20du%20temps
