Rigid cellular plastics - Determination of the volume percentage of open cells and of closed cells

L'ISO 4590 :2016 spécifie un mode opératoire général permettant de déterminer le pourcentage volumique des cellules ouvertes et fermées de plastiques alvéolaires rigides par mesurage, en premier lieu, du volume géométrique d'éprouvettes de ces plastiques, puis du volume impénétrable à l'air de ces éprouvettes.Le mode opératoire permet d'effectuer une correction du volume apparent des cellules ouvertes en tenant compte des cellules de surface ouvertes par la découpe des éprouvettes. Trois méthodes alternatives (méthode 1, méthode 2a et méthode 2b) et les appareillages correspondants sont spécifiés pour le mesurage du volume impénétrable.

Rigid cellular plastics - Determination of the volume percentage of open cells and of closed cells

This International Standard specifies a general procedure for the determination of the volume percentage of open and of closed cells of rigid cellular plastics, by measurement first of the geometrical volume and then of the air-impenetrable volume of test specimens. The procedure includes the correction of the apparent open-cell volume by taking into account the surface cells opened by cutting during specimen preparation. Two alternative methods (method 1 and method 2), and corresponding apparatus, are specified for the measurement of the impenetrable volume. The results obtained from method 2 are intended to be used for comparison purposes only.

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.
