Plastics - Determination of ash - Part 4 : polyamides

La présente partie de l'ISO 3451 spécifie les méthodes de détermination du taux de cendres des polyamides chargés et non chargés. Les modes opératoires généraux indiqués dans la norme ISO 3451-1 sont suivis. Pour les matériaux non chargés, on utilise la méthode A ou la méthode C de l'ISO 3451-1:1997. Pour les matériaux chargés et ceux renforcés de fibres de verre, on suit la méthode A décrite dans l'ISO 3451-1:1997. Pour les matériaux chargés de fibres de verre et contenant un agent ignifugeant, du trioxyde d'antimoine et/ou d'autres additifs volatilisables tels que des pigments de surlure de zinc, une modification a été apportée pour éliminer ces additifs sous forme de composant(s) volatil(s) du brome.

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.
