Title: Tufted carpet tiles, maximum total pile ...en backing (EPD).pdf
As, for all impact categories and all modules (A-D), LCA results show a linear correlation with the total pile weight, it is also possible to calculate LCA results for any product with a total pile weight Px different from those already mentioned in the annex.LCA results can be calculated by using general ‘equation 1’, as shown in the graph below.Graph 1: General formula for the calculation of all impact categories ICX.The following table gives the definition of pile weight categories used in this annex:CategoryLX1X2XnMmax. pile weight per categorylowest pile weight, as declared in the annexL + 100 g/m²X1 + 100 g/m²Xn-1 + 100 g/m²max. pile weight, as declared in the EPD1General Information on use stages B1 to B7LCA results indicate environmental impacts resulting from use stage B1 to B7.
