Polytetrafluoroethylene (ptfe) tubing for aerospace applications. Methods for the determination of the density and relative density.

La masse volumique et la densité sont fréquement utilisées pour suivre les variations de structure physique des échantillons ou pour calculer la quantité de matière nécessaire pour remplir un volume donné. La présente norme définit trois méthodes permettant de déterminer la masse volumique et la densité des tubes en polytétrafluoréthylène (PTFE) utilisés pour la fabrication des tuyauteries flexibles en PTFE, à moyenne et haute pressions et à haute température, pour usages aéronautiques.

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!
