Natural gas - Energy determination (ISO 15112:2018)

This document provides the means for energy determination of natural gas by measurement or by calculation, and describes the related techniques and measures that are necessary to take. The calculation of thermal energy is based on the separate measurement of the quantity, either by mass or by volume, of gas transferred and its measured or calculated calorific value. The general means of calculating uncertainties are also given.
Only systems currently in use are described.
NOTE       Use of such systems in commercial or official trade can require the approval of national authorization agencies, and compliance with legal regulations is required.
This document applies to any gas-measuring station from domestic to very large high-pressure transmission.
New techniques are not excluded, provided their proven performance is equivalent to, or better than, that of those techniques referred to in this document.
Gas-measuring systems are not the subject of this document.

Erdgas - Bestimmung von Energiemengen (ISO 15112:2018)

Dieses Dokument sieht Maßnahmen vor zur Bestimmung von Energiemengen von Erdgas durch Messung oder Berechnung und beschreibt die dabei erforderlichen anzuwendenden Techniken und Maßnahmen. Die Berechnung von thermischer Energie beruht auf der gesonderten Messung der Gasmenge, entweder als Masse oder Volumen des (an Übergabestellen) übertragenen Gases und auf seinem gemessenen oder berechneten Brennwert. Allgemeine Maßnahmen zur Berechnung von Unsicherheiten sind ebenfalls angegeben.
Ausschließlich derzeit verwendete Systeme werden beschrieben.
ANMERKUNG   Der Einsatz derartiger Systeme in kommerziellem oder offiziellem Handel erfordert möglicherweise die Zulassung durch nationale Zulassungsbehörden, und die Übereinstimmung mit gesetzlichen Vorschriften ist erforderlich.
Dieses Dokument gilt für alle Gasmessstationen, von Endkunden im privaten Bereich bis hin zu sehr großen Hochdrucktransportanlagen.
Neue Verfahren sind nicht ausgeschlossen, sofern ihre nachgewiesene Leistungsfähigkeit gleichwertig der oder besser als die jener Techniken ist, auf die in diesem Dokument Bezug genommen wird.
Gasmesssysteme sind nicht Gegenstand dieses Dokuments.

Gaz naturel - Détermination de l'énergie (ISO 15112:2018)

Le présent document fournit les moyens permettant de déterminer l'énergie du gaz naturel par mesurage ou par calcul, et décrit les techniques associées et les mesures nécessaires à prendre. Le calcul de l'énergie thermique est fondé sur le mesurage séparé de la quantité de gaz transféré, exprimée en masse ou en volume, et sur son pouvoir calorifique mesuré ou calculé. Il fournit également les moyens généraux permettant le calcul des incertitudes.
Seuls les systèmes actuellement utilisés sont décrits dans le document.
NOTE       Qu'il s'agisse du secteur privé ou public, l'utilisation de tels systèmes dans le commerce peut requérir l'approbation d'organismes d'agrément nationaux et il est alors nécessaire qu'ils soient conformes aux dispositions de la loi.
Le présent document s'applique à tout poste de comptage de gaz, de la distribution intérieure au transport à très haute pression.
Le recours à de nouvelles techniques est admis sous réserve de performances éprouvées équivalentes ou supérieures aux techniques citées en référence dans le présent document.
Les systèmes de comptage de gaz ne sont pas abordés dans le présent document.

Zemeljski plin - Določevanje energijske vrednosti (ISO 15112:2018)

Ta dokument zagotavlja sredstva za določevanje energijske vrednosti zemeljskega plina z merjenjem ali izračunom ter opisuje s tem povezane tehnike in ukrepe, ki jih je potrebno sprejeti. Izračun toplotne energije temelji na ločenem merjenju količine (masa ali prostornina) prenesenega plina in njegove izmerjene ali izračunane kalorične vrednosti. Podana so tudi splošna sredstva za izračun negotovosti.
Opisani so samo sistemi, ki se trenutno uporabljajo.
OPOMBA: Za uporabo takšnih sistemov v komercialnem ali uradnem trgovanju je morda potrebna odobritev nacionalnih agencij za izdajo dovoljenj in skladnost z zakonskimi predpisi.
Ta dokument se uporablja za vse merilne postaje za plin od gospodinjskih do velikih postaj z visokotlačnim
Nove tehnike niso izključene, če je dokazano, da delujejo enako dobro ali bolje kot tiste, opisane v tem dokumentu.
Sistemi za merjenje plinov niso predmet tega dokumenta.
