Liquefied petroleum gases - Determination of dissolved residues - High-temperature gravimetric method
This Standard specifies a method, for determining the residual matter in liquefied petroleum gases (LPG), which remains after evaporation at 105 °C. This material represents those products deposited in car LPG vaporizers that are subject to a temperature equal to or greater than the boiling temperature of water. The range of determination extends from 50 mg/kg to 100 mg/kg. Higher concentrations can be determined by adjusting the sample size.
The precision data of the method have been determined from 20 mg/kg to 100 mg/kg, with samples amount from 100 g to 50 g.
This method has been developed as a potential replacement of the commonly used method EN ISO 13757 [1], The advantages of the method are that a small quantity of LPG (100 ml) is required.
Flüssiggas - Bestimmung der gelösten Rückstände - Gravimetrisches Hochtemperaturverfahren
Diese Europäische Norm legt ein Verfahren zur Bestimmung des gelösten Rückstands in Flüssiggas (LPG) fest, der nach der Verdampfung bei 105 °C unter Verwendung des Aufblaseverfahrens nach EN ISO 6246 zurück bleibt.
Der Messbereich reicht von 20 mg/kg bis 100 mg/kg. Höhere Konzentrationen können durch Anpassung der Probenmenge bestimmt werden.
Die Präzisionsdaten des Verfahrens wurden für den Bereich von 20 mg/kg bis 100 mg/kg, mit Probenmengen von 100 g bis 50 g, bestimmt.
ANMERKUNG Eine alternative Europäische Norm, EN 15470 [1], beschreibt ein gaschromatographisches Verfahren.
WARNUNG - Die Anwendung dieser Norm kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Norm, vor ihrer Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Maßnahmen eingehalten werden.
Gaz de pétrole liquéfié - Détermination des résidus dissous - Méthode gravimétrique à haute température
La présente norme européenne spécifie une méthode de détermination des matières résiduelles dissoutes dans le gaz de pétrole liquéfié (GPL) qui subsistent après évaporation à 105 °C avec l’équipement d’évaporation au jet décrit dans l’EN ISO 6246.
L’intervalle de mesure s’étend sur la plage de 20 mg/kg à 100 mg/kg. Des concentrations plus élevées peuvent être mesurées en ajustant la taille de l’échantillon.
Les valeurs de fidélité de cette méthode ont été fixées dans un intervalle de concentration compris entre 20 mg/kg et 100 mg/kg avec des échantillons de 100 g à 50 g.
NOTE La norme EN 15470 [1] présente une méthode par chromatographie en phase gazeuse.
AVERTISSEMENT - L'utilisation de la présente Norme peut impliquer l'intervention de produits, d'opérations et d'équipements à caractère dangereux. La présente Norme n'est pas censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité des utilisateurs de cette norme de prendre les mesures appropriées pour assurer la sécurité et préserver la santé du personnel avant son application, et pour répondre aux exigences réglementaires et statutaires à cette fin.
Utekočinjeni naftni plini - Določevanje raztopljenih ostankov - Visokotemperaturna gravimetrijska metoda
Ta standard določa metodo za določevanje ostankov snovi v utekočinjenih naftnih plinih (LPG), ki ostanejo po izhlapevanju pri 105 °C. Ta material predstavlja tiste izdelke, ki so naneseni na avtomobilske uparjalnike utekočinjenih naftnih plinov, ki so izpostavljeni temperaturi, enaki ali večji od temperature vrelišča vode. Razpon določanja je 50–100 mg/kg. Višje koncentracije je mogoče določiti s prilagajanjem velikosti vzorca.
Podatki o natančnosti metode so določeni 20–100 mg/kg pri količini vzorca 100–50 g.
Ta metoda je bila razvita kot možna zamenjava običajno uporabljene metode, ki je opisana v standardu EN ISO 13757 [1]. Prednost te metode je v tem, da je potrebna majhna količina (100 ml) utekočinjenega naftnega plina.
