Gaz de pétrole liquéfiés — Méthode d’échantillonnage
| Published By | Publication Date | Number of Pages |
| ISO | 2001-07 | 12 |
La présente Norme Internationale spécifie une méthode pour le prélèvement d'échantillons de gaz de pétrole liquéfiés non réfrigérés (GPL). Elle s'applique aux prélèvements effectués à partir de réservoirs pour obtenir des échantillons destinés à des essais de laboratoire sur des produits conformes à l'ISO 9162. Cette Norme Internationale s'applique aux prélèvements d'échantillons destinés à l'analyse des composants selon l'ISO 7941. Elle ne s'applique pas aux prélèvements d'échantillons destinés à l'analyse des traces de composés à bas point d'ébullition. S'il est nécessaire d'analyser des traces de composés à bas points d'ébullition, un système à volume variable tel que celui décrit dans la méthode ASTM D 3700 est recommandé.
