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.For textile floor coverings only modules B1 (use) and B2 (maintenance) are taken into account. Modules B3 (repair), B4 (replacement), B5 (refurbishment), B6 (operational energy use) and B7 (operational water use) are not relevant during the service life of textile floor coverings.Module B1 ‘use’ includes emissions to the indoor air during the use stage. Relevant emissions only occur in the first year of life (see LCA: Calculation rules).
