Horology. Time transmission from masterclock to secondary clocks by coded signals on double-wound. Requirements.

Il a été jugé utile de normaliser, sur un plan national, un code de distribution de l'heure et son mode de transmission, dans le but de constituer une référence nationale. D'autres codes et modes de transmission, ne faisant pas l'objet de normes, peuvent être également utilisés lorsqu'ils s'avèrent répondre plus spécifiquement à certains besoins.

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.

With Requirements, quickly access the main part of the normative text!
