Air quality - Workplace atmosphere - Determination of the number concentration of fibres by phase contrast optical microscopy - Membrane filter method

Cette méthode s'applique à l'échantillonnage régulier et à l'évaluation d'échantillons tels qu'ils sont requis pour déterminer l'exposition des individus aux fibres et contrôler la présence de celles-ci sur les lieux de travail. Son utilisation doit se limiter à l'air des lieux de travail où les fibres inorganiques prédominent.

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.
