1   Scope

This section of BS 6920 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 [A2_start]Under the relevant National Regulations [4] to [10], the National Regulator may specify additional provisions in some cases and will assess the significance of the results obtained.[A2_end]
