EUROLAB laboratory provides testing and compliance services within the scope of ISO 6503 standard. The method is the principle for coating materials with a lead content in the range of about 0.01% (m/m) to 2% (m/m), also applicable to products with a total lead content of more than 2%.
Two methods are given. The principle of the dry ashing method consists of evaporating a test portion to dryness and ashing at 475 °C and extracting any lead in the residue with hydrochloric acid; that of the wet oxidation method consists of wet oxidation of a test portion with a mixture of sulfuric acid and hydrogen peroxide, or with sulfuric acid and nitric acid, and extraction of any lead in the residue with a solution of EDTA and ammonia.
If the composition of the product to be tested is unknown, perform qualitative tests for the presence of cellulose nitrate and antimony. If the results of these tests do not confirm the absence of cellulose nitrate and antimony, perform the entire procedure.
