BS 6920-2.2.1:2000+A3:2014

This subsection of BS6920 describes a method designed to assess the ability of a product to impart a discernible odour and/or flavour to water intended for human consumption. The method is applicable for most types of non-metallic products used in contact with drinking water. * It is not applicable for testing the following product types: multilayered pipes and hoses in which the outer material differs from the inner (water contact) material, together with barrier pipes and reinforced flexible hoses (see BS6920‑2.2.2); hoses (with or without reinforcement) for use in equipment used for food and drink (see BS6920‑2.2.3) . NOTE1 Procedures for testing odours and flavours imparted to water by flexible hoses (with or without reinforcement) in their final form (i.e. before assembly) and flexible hoses (with or without reinforcement) intended for use in equipment used for food and drink preparation are given in BS6920‑2.2.2 and BS6920‑2.2.3 respectively. NOTE2 Under the relevant National Regulations [1] to [7], the National Regulator may specify additional provisions in some cases and will assess the significance of the results obtained.
