The relative weight of a gas or vapor as compared with some specific standard such as air. 2, record 1, English, - vapour%20density
Record number: 1, Textual support number: 1 OBS
Materials lighter than air have vapour densities of less than 1.0. Materials heavier than air have vapour densities greater than 1.0. All vapours and gases will mix with air, but the lighter materials will tend to rise and dissipate (unless confined). Heavier vapours and gases are likely to concentrate in low or enclosed places, creating fire, explosion, or health hazards. 3, record 1, English, - vapour%20density

Masse relative d’un gaz ou d’une vapeur, comparée à un gaz étalon, l’hydrogène ou l’air. 2, record 1, French, - densit%C3%A9%20de%20vapeur
Record number: 1, Textual support number: 1 CONT
La densité de vapeur est le poids par unité de volume d’une substance à l'état de gaz pur ou de vapeur. Dans les FTSS [fiches techniques santé-sécurité], la densité de vapeur est normalement donnée sous forme d’un rapport entre la densité du gaz ou de la vapeur et celle de l'air. On attribue à l'air la valeur arbitraire de 1. Les gaz légers(densité inférieure à 1) comme l'hélium s’élèvent dans l'air. Les vapeurs et gaz lourds(densité supérieure à 1) peuvent s’accumuler vers le bas, dans les puits ou à la surface du sol, s’il n’ y a pas de ventilation adéquate. 3, record 1, French, - densit%C3%A9%20de%20vapeur

The Baumé hydrometer, named for the French chemist Antoine Baumé, is calibrated to measure specific gravity on evenly spaced scales; one scale is for liquids heavier than water, and the other is for liquids lighter than water. 4, record 2, English, - Baum%C3%A9%20hydrometer

Aréomètre Baumé. C'est un aréomètre à poids constant. Sa graduation-en degrés Baumé-, qui n’ a plus cours légal depuis mai 1961, est arbitraire, mais permet d’évaluer la concentration de n’ importe quelle solution avec la même unité et le même appareil imaginé par Baumé. 1, record 2, French, - ar%C3%A9om%C3%A8tre%20Baum%C3%A9
