Gaz de pétrole liquéfiés — Détermination de la pression de vapeur relative — Méthode GPL
| Published By | Publication Date | Number of Pages |
| ISO | 1996-10 | 12 |
La présente Norme internationale prescrit une méthode pour la détermination des pressions de vapeurs relatives des gaz de pétrole liquéfiés (voir l'article 3) à des températures comprises entre 35 °C et 70 °C.
NOTES 1 Les renseignements à propos de la pression de vapeur des gaz de pétrole liquéfiés sont nécessaires pour résoudre les problèmes de choix des capacités des récipients de stockage, de transport et des équipements dans lesquels les GPL sont utilisés, en vue d'assurer une manipulation sans danger de ces produits et pour assurer que les pressions maximales de service envisagées n'excèdent pas celles dans les conditions ambiantes de fonctionnement prévues. 2 La pression de vapeur des gaz de pétrole liquéfiés est une mesure indirecte de la température minimale de début de vaporisation. Elle peut aussi être considérée comme une indication sur le constituant le plus volatil présent dans le produit.
