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.
