Zusammenfassung:	ACCORDING TO A FIRST EMBODIMENT, THE PRESENT INVENTION RELATES TO THE USE FOR TRANSPORTING PETROL IN A SERVICE STATION OF A HOSE COMPRISING: AN INNER LAYER IN CONTACT WITH THE FLUID TO BE TRANSPORTED, CONSISTING OF A FLUOROPOLYMER ONTO WHICH AN UNSATURATED MONOMER HAS BEEN IRRADIATION-GRAFTED AND, DIRECTLY ATTACHED TO THE LATTER, A POLYOLEFIN OUTER LAYER. ACCORDING TO A VARIANT, THE HOSE COMPRISES A FLUOROPOLYMER, PREFERABLY PDVF, LAYER PLACED BESIDE THE IRRADIATION-GRAFTED FLUOROPOLYMER. ACCORDING TO A SECOND EMBODIMENT, THE HOSE COMPRISES: A CENTRAL LAYER CONSISTING OF AN IRRADIATION- GRAFTED FLUOROPOLYMER AND, DIRECTLY ATTACHED TO THE LATTER, A POLYOLEFIN OUTER LAYER AND A POLYOLEFIN INNER LAYER. THE POLYOLEFIN INNER LAYER IS THE LAYER IN CONTACT WITH THE PETROL. ACCORDING TO A VARIANT, THE IRRADIATION-GRAFTED FLUOROPOLYMER LAYER IS REPLACED WITH A LAYER OF A BLEND OF A FLUOROPOLYMER, PREFERABLY PVDF, AND OF AN IRRADIATION-GRAFTED FLUOROPOLYMER. ACCORDING TO A THIRD EMBODIMENT, THE HOSE COMPRISES: A CENTRAL LAYER CONSISTING OF A POLYOLEFIN AND, DIRECTLY ATTACHED TO THE LATTER, AN IRRADIATION-GRAFTED FLUOROPOLYMER OUTER LAYER AND AN IRRADIATION-GRAFTED FLUOROPOLYMER INNER LAYER. ACCORDING TO A VARIANT, AT LEAST ONE OF. THE LAYERS OF IRRADIATION-GRAFTED FLUOROPOLYMER (OPTIONALLY BLENDED WITH A FLUOROPOLYMER) IS COVERED W.ITH A FLUOROPOLYMER, PREFERABLY PVDF, LAYER. THE IRRADIATION-GRAFTED FLUORO- POLYMER LAYER IS A TIE LAYER BETWEEN THE PVDF LAYER AND THE POLYOLEFIN LAYER. THE INNER LAYER IN CONTACT WITH THE PETROL IS THEREFORE EITHER A FLUOROPOLYMER (PREFERABLY PVDF) LAYER OR AN IRRADIATION-GRAFTED FLUOROPOLYMER LAYER OR A LAYER OF A BLEND OF A FLUOROPOLYMER, PREFERABLY PVDF, AND OF AN IRRADIATION- GRAFTED FLUOROPOLYMER.
