The method is applicable to products having Zn contents equal to or greater than 0,002 % (m/m). Dissolution of a test portion by hydrochloric acid under pressure. Aspiration of the solution into an acetylene-air flame and photometric measurement of the absorption of the 213,7 nm line emitted by a hollow-cathode zinc lamp. The dissolution of the sample can also be carried out by an alkaline fusion. This method is given in the annex. Replaces ISO Recommendation R 2071-1971.
