Thermoplastics pipes and fittings — Vicat softening temperature — Part 1: General test method

Le présent document prescrit une méthode générale de détermination de la température de ramollissement Vicat des tubes et des raccords en matières thermoplastiques et comporte l''adaptation de la méthode B de l''ISO 306:1994, utilisant une force de 50 N. La présente méthode est seulement applicable aux matières thermoplastiques pour lesquelles elle permet de mesurer la température à laquelle leur ramollissement devient rapide. Elle n''est pas applicable aux polymères cristallins ni semi-cristallins.

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!
