Determination of certain substances in electrotechnical products - Part 2: Disassembly, disjointment and mechanical sample preparation

IEC 62321-2:2013 provides strategies of sampling along with the mechanical preparation of samples from electrotechnical products, electronic assemblies and electronic components. These samples can be used for analytical testing to determine the levels of certain substances as described in the test methods in other parts of IEC 62321. Restrictions for substances will vary between geographic regions and from time to time. This Standard describes a generic process for obtaining and preparing samples prior to the determination of any substance which are under concern.

Verfahren zur Bestimmung von bestimmten Substanzen in Produkten der Elektrotechnik - Teil 2: Demontage, Zerlegung und mechanische Probenvorbereitung

Détermination de certaines substances dans les produits électrotechniques - Partie 2: Démontage, désassemblage et préparation mécanique de l'échantillon

La CEI 62321-2:2013 fournit des stratégies d'échantillonnage ainsi que la préparation mécanique d'échantillons de produits électrotechniques, ensembles électroniques et composants électroniques. Ces échantillons peuvent être utilisés pour un essai analytique visant à déterminer les niveaux de certaines substances, comme décrit dans les méthodes d'essai des autres parties de la CEI 62321. Les restrictions concernant les substances varient selon les régions géographiques et de temps à autres. La présente norme décrit un processus général permettant d'obtenir et de préparer des échantillons avant de déterminer toute substance posant problème.

Določevanje posameznih snovi v elektrotehničnih izdelkih - 2. del: Razstavljanje, odklop in mehanska priprava vzorca (IEC 62321-2:2013)

Standard 62321-2 določa strategije vzorčenja skupaj z mehansko pripravo vzorcev iz elektrotehničnih izdelkov, elektronskih sklopov in elektronskih komponent. Ti vzorci se lahko uporabijo za analitično testiranje za določitev vsebnosti nekaterih snovi, kot je opisano v testnih metodah v drugih delih IEC 62321. Omejitve za snovi se razlikujejo med geografskimi regijami in od časa do časa. Ta standard opisuje splošen postopek za pridobitev in pripravo vzorcev pred določitvijo katere koli zadevne snovi. Ta standard ne ponuja: - popolnih smernic za vsak izdelek, ki ga je mogoče razvrstiti kot elektrotehnično opremo. Ker hkrati z nenehnimi industrijskimi inovacijami obstaja veliko različnih elektrotehničnih komponent z različnimi zgradbami in postopki, je nerealno, da bi poskušali zagotoviti postopke za razstavljanje vsakega tipa sestavnega dela pri stikališčih; – smernice glede drugih poti za zbiranje dodatnih informacij o nekaterih snoveh v proizvodu, čeprav so zbrane informacije pomembne za strategije vzorčenja v tem standardu; – varno razstavljanje in navodila za mehansko razstavljanje pri stikališčih, povezana z elektrotehničnimi izdelki (npr. stikala, ki vsebujejo živo srebro) in reciklažno industrijo (npr. kako ravnati z zasloni CRT ali varno odstraniti baterije). Glejte standard IEC 62554 [2] za razstavljanje pri stikališčih in pripravo mehanskih vzorcev fluorescenčnih sijalk, ki vsebujejo živo srebro; – opredelitev »enote« kot vzorca; – postopke vzorčenja za embalažo in embalažne materiale; – analitične postopke za merjenje ravni določenih snovi. To je zajeto v drugih standardih (na primer drugih delih IEC 62321), ki so navedeni kot »preskusni standard« v tem standardu; – smernice za oceno skladnosti.
