To harmonize the standard under the MID, 2004/22/EC.  The Target dates have been shortened in order to meet the enforcement date of the MID.

Gaszähler - Drehkolbengaszähler

Der dritte Absatz ist zu streichen und wie folgt zu ersetzen:
Die vorliegende Norm gilt für Zähler an Standorten, an denen unbedeutende Schwingungen und Erschütterungen auftreten können, sowie an
   geschlossenen Standorten (innen oder außen mit dem vom Hersteller vorgeschriebenen Schutz) mit oder ohne Betauung
oder, bei entsprechender Angabe durch den Hersteller,
   offenen Standorten (außen ohne Abdeckung) mit oder ohne Betauung
sowie an Standorten mit elektromagnetischen Störungen.
Der folgende vierte Absatz ist neu einzufügen:
Soweit in dieser Norm nicht anders angegeben:
   sind alle dargestellten Drücke als Überdrücke zu verstehen;
   werden alle Einflussgrößen außer der geprüften Einflussgröße relativ konstant bei ihrem Referenzwert gehalten.

Compteurs à gaz - Compteurs à gaz à pistons rotatifs

Supprimer le troisième paragraphe et le remplacer par ce qui suit :
La présente norme s'applique aux compteurs installés dans des endroits où les vibrations et les chocs sont peu importants et :
   dans des endroits fermés (à l'intérieur ou à l'extérieur avec la protection spécifiée par le fabricant) avec ou sans condensation d'humidité ;
ou, si le constructeur le spécifie,
   dans des endroits ouverts (à l'extérieur sans protection) avec ou sans condensation d'humidité ;
ainsi que dans des endroits avec interférences électromagnétiques.
Insérer ce qui suit comme nouveau quatrième paragraphe :
Sauf spécification contraire dans la présente norme :
   toutes les pressions sont des pressions relatives ;
   toutes les grandeurs d'influence, sauf celle qui est soumise à l'essai, sont maintenues constantes à leur valeur de référence.
