Determination of certain substances in electrotechnical products - Part 5: Cadmium, lead and chromium in polymers and electronics and cadmium and lead in metals by AAS, AFS, ICP-OES and ICP-MS

IEC 62321-5:2013 describes the four test methods for lead, cadmium and chromium in polymers, metals and electronics, namely AAS (atomic absorption spectrometry), AFS (atomic fluorescence spectrometry), ICP-OES (inductively coupled plasma optical emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry) as well as several procedures for preparing the sample solution from which the most appropriate method of analysis can be selected by experts.

Détermination de certaines substances dans les produits électrotechniques - Partie 5: Du cadmium, du plomb et du chrome dans les polymères et les produits électroniques, du cadmium et du plomb dans les métaux par AAS, AFS, ICP-OES et ICP-MS

La CEI 62321-5:2013 décrit les quatre méthodes d'essai pour le plomb, le cadmium et le chrome dans les polymères, les métaux et les produits électroniques, à savoir l'AAS (spectrométrie d'absorption atomique), l'AFS (spectrométrie de fluorescence atomique), l'ICP-OES (spectrométrie d'émission optique couplée à un plasma induit) et l'ICP-MS (spectrométrie de masse couplée à un plasma induit), ainsi que plusieurs procédures de préparation de la solution d'échantillon à partir desquelles les experts peuvent choisir la méthode d'analyse la plus appropriée.

Določevanje posameznih snovi v elektrotehničnih izdelkih - 5. del: Določevanje kadmija, svinca in kroma v polimerih in elektronskih elementih ter kadmija in svinca v kovinah z AAS, AFS, ICP-OES in ICP-MS (IEC 62321-5:2013)

Standard EN-IEC 62321-5 opisuje preskusne metode za določevanje svinca, kadmija in kroma v polimerih in elektronskih elementih z atomsko absorpcijsko spektrometrijo (AAS), atomsko fluorescenčno spektrometrijo (AFS), optično emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP-OES) in masno spektrometrijo z induktivno sklopljeno plazmo (ICP-MS). Ta standard navaja določanje kadmija (Cd), svinca (Pb) in kroma (Cr) v elektronskih elementih. Zajema tri vrste matric: polimere/polimerne obdelovance, kovine in zlitine ter elektroniko. Ta standard se nanaša na vzorec kot predmet, ki se obdela in meri. Kaj ta vzorec je ali kako ga pridobiti, določa subjekt, ki izvaja preskuse. Dodatna navodila o pridobivanju reprezentativnih vzorcev iz končnih elektronskih izdelkov za testiranje ravni reguliranih snovi je mogoče najti v standardu IEC 62321-2. Opozoriti je treba, da lahko izbira in/ali določanje vzorca vpliva na razlago rezultatov preskusa. Ta standard opisuje uporabo štirih metod, in sicer AAS (atomska absorpcijska spektrometrija), AFS (atomska fluorescentna spektrometrija), ICP-OES (optična emisijska spektrometrija z induktivno sklopljeno plazmo) in ICP-MS (masna spektrometrija z induktivno sklopljeno plazmo), kot tudi več postopkov za pripravo vzorčne raztopine, s pomočjo katere lahko strokovnjaki izberejo najbolj primerno metodo analize. Ker je z analizo šestvalentnega kroma tega včasih težko določiti v polimerih in elektroniki, ta standard uvaja presejalne metode za krom v polimerih in elektroniki, z izjemo atomske absorpcijske spektrometrije. Analiza kroma zagotavlja informacije o obstoju šestvalentnega kroma v materialih. Vendar z analizo elementov ni mogoče selektivno zaznati šestvalentnega kroma. Z njo se določi vsebnost kroma v vseh oksidacijskih stanjih v vzorcih. Če vsebnost kroma preseže mejo za šestvalentni krom, je treba testirati vsebnost šestvalentnega kroma. Preskusni postopki, opisani v tem standardu, so namenjeni zagotavljanju najvišje stopnje točnosti in natančnosti za vsebnosti svinca, kadmija in kroma v tem območju; pri optični emisijski spektrometriji z induktivno sklopljeno plazmo in atomski absorpcijski spektrometriji od 10 mg/kg za svinec, kadmij in krom, pri masni spektrometriji z induktivno sklopljeno plazmo od 0,1 mg/kg za svinec in kadmij, pri atomski fluorescentni spektrometriji pa od 10 mg/kg svinec in 1,5 mg/kg za kadmij. Postopki se lahko uporabljajo tudi za višje koncentracije. Zaradi njihove stabilnosti ta standard ne velja za materiale, ki vsebujejo polifluorirane polimere. Če je v analitskem postopku uporabljena žveplova kislina, obstaja tveganje izgube svinca, kar povzroči nepravilne nizke vrednosti tega analita. Ob tem žveplova in fluorovodikova kislina nista primerni za določanje kadmija z atomsko absorpcijsko spektrometrijo, saj ovirata zmanjšanje vsebnosti kadmija. Omejitve in tveganja se pojavijo zaradi koraka z raztopino vzorca, pride lahko npr. do obarjanja ciljnega ali drugih elementov, pri čemer je treba ostanke preveriti posebej ali jih raztopiti na drug način in jih nato združiti z vzorčno raztopino.
