IEC 62321-3-2:2020

Determination of certain substances in electrotechnical products - Part 3-2: Screening - Fluorine, bromine and chlorine in polymer and electronics by combustion-ion chromatography (C-IC)

IEC 62321-3-2:2020 specifies the screening analysis of fluorine, chlorine and bromine in polymers and electronics using combustion-ion chromatography (C-IC). IEC 62321-3-2:2020 cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) In the previous edition, a screening test method for bromine (Br) content only was provided. In this edition, a screening test method by C-IC for fluorine (F), chlorine (Cl) and bromine (Br) has been added to the normative part of the document.
b) A screening test method by C-IC for iodine (I) has been added in Annex D (informative).
It has the status of a horizontal standard in accordance with IEC Guide 108.

Détermination de certaines substances dans les produits électrotechniques - Partie 3-2: Détection - Fluor, chlore et brome dans les polymères et les produits électroniques par combustion - Chromatographie ionique (C-CI)

L'IEC 62321-3-2:2020 spécifie une méthode d’analyse par détection du fluor, du chlore et du brome dans les polymères et les produits électroniques en appliquant la technique de combustion-chromatographie ionique (C-CI). L'IEC 62321-3-2:2020 annule et remplace la première édition publiée en 2013. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
a) La précédente édition présentait une méthode d’essai de détection pour le brome (Br) seulement. La présente édition ajoute, dans sa partie normative, une méthode d’essai de détection par C-CI pour le fluor (F), le chlore (Cl) et le brome (Br).
b) Une méthode d’essai de détection par C-CI de l’iode a été ajoutée à l’Annexe D (informative).
Elle a le statut d'une norme horizontale conformément au Guide 108 de l'IEC.
