Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 4 : sampling and analysis of dioxin-like PCBs

Le présent document spécifie les modes opératoires de prélèvement à partir de sources fixes, d'extraction, de purification, d'identification et de quantification des PCB de type dioxine. Le mode opératoire décrit pose les exigences pour mesurer les congénères des PCB données à l'Annexe A (voir Tableau A.1). Il est applicable aux 12 PCB non-ortho et mono-ortho désignés par l'OMS. Il est optimisé pour mesurer des concentrations de PCB d'environ 0,01 ng d'OMS-TEQPCB/m3. En plus des 12 PCB non-ortho et mono-ortho, le présent document est également applicable pour mesurer d'autres congénères de PCB comme le "marqueur de PCB" 28, 52, 101, 138, 153, 180 (voir Annexe F). Le présent document spécifie un cadre d'exigences de contrôle qualité pour toute méthode appliquée de prélèvement, d'extraction, de purification, d'identification et de quantification de PCB.

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.

With Requirements, quickly access the main part of the normative text!

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
