Flüssiggase-Probenahme (ISO 4257:2001)

Diese Internationale Norm beschreibt das Verfahren, das anzuwenden ist, um Proben von ungekühlten Flüssiggasen (LPG) zu erhalten. Sie ist anwendbar auf die Entnahme von Proben aus Transportbehältern und die Bereitstellung von Proben für Laboruntersuchungen von Produkten, die den Anforderungen von ISO 9162 genügen.
Diese Internationale Norm ist auch zur Entnahme von Proben zur Ermittlung der Zusammensetzung nach ISO 7941 anwendbar. Sie ist nicht anwendbar zur Entnahme von Proben zur Spurenanalyse niedrig siedender Komponenten. Wenn eine Spurenanalyse niedrig siedender Komponenten erforderlich ist, ist ein Probenahme-gefäß mit variablem Volumen zu benutzen, wie es in ASTM D 3700 beschrieben wird ) .

Gaz de pétrole liquéfiés - Méthode d'échantillonnage (ISO 4257:2001)

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.
