Chemical analysis of ferrous materials. Determination of bore in steel. Spectrophotometric method.

La présente norme décrit une méthode de dosage du bore par spectrophotométrie dans les aciers, pour des teneurs en bore comprises entre 0,000 4 % et 0,012 0 % (m/m). Cette méthode est basée sur la formation d'un complexe par traitement aux acides et mesure de l'absorbance de la solution à une longueur d'onde de 543 nm.

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.
