Leather - Chemical determination of chromium(VI) content in leather - Part 2: Chromatographic method (ISO 17075-2:2017)

ISO 17075-2:2017 specifies a method for determining chromium(VI) in solutions leached from leather under defined conditions. The method described is suitable to quantify the chromium(VI) content in leathers down to 3 mg/kg.
ISO 17075-2:2017 is applicable to all leather types.
The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH, extraction time, etc.) are not comparable with the results produced by the procedure described in this document.
If a leather sample is tested with both ISO 17075-1 and this document, the results obtained with this document are considered as the reference. The advantage of the method described in this document is that there are no interferences from the colour of the extract. Nevertheless, interlaboratory trials do not show significant differences (see Annex D) and the results are comparable between both methods.

Leder - Chemische Bestimmung des Chrom(VI)-Gehalts in Leder - Teil 2: Chromatographie (ISO 17075-2:2017)

Cuir - Détermination chimique de la teneur en chrome(VI) du cuir - Partie 2: Méthode chromatographique (ISO 17075-2:2017)

ISO 17075-2:2017 spécifie une méthode de détermination de la teneur en chrome(VI) de solutions obtenues par lessivage du cuir dans des conditions définies. La méthode décrite est adaptée à la quantification dans les cuirs de teneurs en chrome(VI) à partir de 3 mg/kg.
ISO 17075-2:2017 est applicable à tous les types de cuir.
Les résultats obtenus avec cette méthode sont strictement tributaires des conditions d'extraction. Les résultats obtenus avec d'autres modes opératoires d'extraction (solution d'extraction, pH, durée d'extraction, etc.) ne sont pas comparables aux résultats acquis avec le mode opératoire décrit dans le présent document.
Si un échantillon de cuir est soumis à essai selon l'ISO 17075‑1 et le présent document, les résultats obtenus avec le présent document sont considérés comme les valeurs de référence. L'avantage de la méthode décrite dans le présent document est qu'il n'y a pas d'interférence due aux colorants de l'extrait. Néanmoins, les essais interlaboratoires ne montrent pas de différences significatives (voir l'Annexe D) et les résultats obtenus avec chacune des deux méthodes sont comparables.

Usnje - Kemijsko določevanje kroma (VI) v usnju - 2. del: Kromatografska metoda (ISO 17075-2:2017)

Ta dokument določa metodo za določanje kroma (VI) v raztopinah, izluženih iz usnja pod določenimi pogoji. Opisana metoda je primerna za kvantifikacijo vsebnosti kroma (VI) v usnju do vrednosti najmanj 3 mg/kg.
Ta dokument se uporablja za vse vrste usnja.
Rezultati te metode so strogo odvisni od pogojev ekstrakcije. Rezultati,
pridobljeni z drugimi postopki ekstrakcije (ekstrakcijska raztopina, pH, čas ekstrakcije ipd.) niso primerljivi z rezultati, pridobljeni s postopkom, opisanim v tem dokumentu.
Če je vzorec usnja preskušen v skladu s standardom ISO 17075-1 in tem dokumentom, se rezultati, pridobljeni s tem
dokumentom, obravnavajo kot referenčni. Prednost v tem dokumentu opisane metode je, da barva ekstrakta ne povzroča motenj. Kljub temu medlaboratorijski preskusi ne odražajo bistvenih razlik (glej dodatek D) in rezultati obeh metod so primerljivi.
