Abstract:
Provided is a method of determining whether a multilayer tubular structure (MLT) satisfies an extractables test by filling the multilayer tubular structure MLT with an alcohol-containing petrol of FAM B type to obtain a filled MLT and measuring the amount of extractable material. The MLT satisfies the extractables test when the residue of the filtrate is less than or equal to 6 g/m2 of the inner surface area of the MLT.
