ISO 10258:2015 specifies two titrimetric methods for the determination of the copper content of copper sulfide concentrates in the range 15 % (m/m) to 50 % (m/m), using sodium thiosulfate after separation (method 1) or without separation (method 2) of copper from interfering elements.
Zinc sulfide concentrates — Determination of silver content — Acid dissolution and flame atomic abso...
ISO 15247:2015 specifies an acid dissolution and flame atomic absorption spectrometric method for the determination of silver content of zinc sulfide concentrates.
The method is applicable to the determination of silver in zinc sulfide concentrates containing up to 60 % (m/m) zinc in the form of zinc blende and related materials.
The method is applicable to silver contents from 10 g/t to 500 g/t.

Leather — Determination of ethoxylated alkylphenols — Part 1: Direct method
ISO 18218-1:2015 is a method for determining ethoxylated alkylphenols (nonyphenol ethoxylate [NPEOn with 1 ≤ n ≤ 16] and octylphenol ethoxylate [OPEOn with 1 ≤ n ≤ 16]) in leather. This direct method is especially suitable where a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols.
This method requires the use of high-performance liquid chromatography…
Leather — Determination of ethoxylated alkylphenols — Part 2: Indirect method
ISO 18218-2:2015 is a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS).
The analysis of the alkylphenol ethoxylate is made by cleaving the…
