Exposure limits have different names and different meanings depending on who developed them and whether or not they are legal limits. For example, Threshold Limit Values (TLVs) are exposure guidelines developed by the American Conference of Governmental Industrial Hygienists (ACGIH). They have been adopted by several Canadian governments as their legal limits. Permissible Exposure Limits (PELs) are legal exposure limits in the United States.  5, record 1, English, - exposure%20limit

Pour estimer la vibration globale du corps (...) la norme [ISO 2631-1978 (F] (...) permet d'évaluer (...) les risques pour la santé et la sécurité des travailleurs. La valeur proposée correspond (...) au concept de valeur limite d'exposition (VLE) adopté en hygiène du travail puisqu'elle détermine le niveau d'accélération en fonction de la fréquence et de la durée qui ne doit pas être dépassé (...) On peut la décrire comme une limite d'intégrité physique et elle est désignée dans les graphiques comme "limite d'exposition".  2, record 1, French, - limite%20d%27exposition

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 4, 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 4, French, - limite%20d%27exposition%20moyenne%20pond%C3%A9r%C3%A9e%20en%20fonction%20du%20temps
