Ce document décrit, en détail, des méthodes pour les essais et contrôles de réception de compteurs de la classe 2, neufs, et livrés en grandes quantités. Dans ce document on a admis des limites d'erreur plus écartées que celles admises pour les essais de type, spécifiées dans la publication appropriée : - parce que les tolérances sur les conditions d'essais de réception sont plus larges que celles admises pour les essais de type; - parce que le déplacement de l'axe des abscisses n'est pas applicable aux essais de réception; - pour tenir compte de la manutention des compteurs.

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.
