Rubber. Determination of metal content by atomic absorption spectrometry. Part 3 : determination of copper content.

Le cuivre est considéré comme un métal poison susceptible de favoriser, sous certaines formes, l'oxydation des caoutchoucs insaturés, caoutchouc naturel en particulier. Le dosage du cuivre longtemps pratiqué sur le caoutchouc sec a été remplacé par la détermination de l'indice de rétention de plasticité "PRI" qui permet d'apprécier le degré de contamination par les métaux poisons fer, cuivre et manganèse. Cependant, certains utilisateurs ou laboratoires recherchent encore la teneur en cuivre dans le caoutchouc sec.

Rubber - Determination of metal content by atomic absorption spectrometry - Part 3 : determination of copper content

<p>ISO 6101-3:2014 specifies an atomic absorption spectrometric method for the determination of the copper content of rubbers. The method is applicable to raw rubber and rubber products having copper contents above 1 ppm. Copper contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and/or to the concentrations of the solutions used. The use of the standard additions method can lower the bottom limit of detection.</p>

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.
