Natural gas - Determination of composition and associated uncertainty by gas chromatography - Part 1 : general guidelines and calculation of composition

L'ISO 6974-1:2012 donne des méthodes de calcul des fractions molaires des constituants du gaz naturel et spécifie les exigences de traitement des données pour déterminer les fractions molaires des constituants. L'ISO 6974-1:2012 fournit à la fois des méthodes d'analyse unique et multiple, mais aussi un étalonnage multipoint, ou une évaluation des performances de l'analyseur suivie d'un étalonnage en un seul point. L'ISO 6974‑1:2012 indique les procédures pour le calcul des fractions molaires brutes et traitées (par exemple normalisées), et des incertitudes associées, pour tous les constituants. Les procédures données dans l'ISO 6974‑1:2012 s'appliquent au traitement des données obtenues à partir d'analyses uniques ou répétées d'un échantillon de gaz naturel.

Natural gas - Determination of composition and associated uncertainty by gas chromatography - Part 2 : uncertainty calculations

This part of ISO 6974 describes the process required to determine the uncertainty associated with the mole fraction for each component from a natural gas analysis in accordance with ISO 6974‑1.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
