Huiles essentielles — Détermination de la densité relative à 20 °C — Méthode de référence
| Published By | Publication Date | Number of Pages |
| ISO | 1998-12 | 8 |
La présente Norme internationale spécifie la méthode de référence pour la détermination de la densité relative à 20 °C des huiles essentielles.
NOTE S'il est nécessaire d'opérer à une température différente en raison de la nature de l'huile essentielle, la température doit être indiquée dans la Norme internationale relative à l'huile essentielle considérée. La correction moyenne, aux environs de 20 °C, est de 0,000 7 à 0,000 8 par degré Celsius.
