SPECIFICATION FOR Suitability of non-metallic products for use in contact with water intended for human consumption with regard to their effect on the quality of the water Part 2:6 : Methods of test - The extraction of metals
This part of SS 375 specifies the test procedure for assessing the leachability of metals from non-metallic products when used in contact with water intended for human consumption.
NOTE 1 - In view of the type of product tested and the amounts of additives present, a limiting level of solubility in the extract water (saturation) is unlikely to be attained.
NOTE 2 - The limit of detection and sensitivity of the method vary according to the particular metal being analysed (see clause 8).
NOTE 3 - The National Regulator may specify additional provisions in some cases and will assess the significance of the results obtained.
