same elementary flow for different imported data records can be quite different
(see Section 3.7.6). It must therefore be made sure that the software is capable of
correctly assigning all designations of inputs and outputs in the study.
In Tables 4.22–4.28 the selected inventory parameters for the impact categories
are listed in accordance with Section 3.7 in the column ‘inventory result’. The
impact indicator values can be calculated by use of the characterisation factors in
accordance with Section 4.6.1. The result as a sum in each impact category refers to
the fU of the packing system, here, supply of 1000 l fruit juice/nectar in 1-l-beverage
carton with closure at the point of sale.
