适用范围：This standard is applicable for internally coated aluminium tubes, mainly used for the packing ofpharmaceutical, cosmetic, hygiene, food or other household products.The internal coating is used as a barrier and should avoid any contact between aluminium and the product.This standard defines two alternative methods - copper sulphate and sodium chloride method - to detect theelectrolyte conductivity as one criterion for the quality of the internal coating.NOTE The electrolyte conductivity of the internal coating is only one criterion for evaluation of the quality of aninternal coating. It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint onpossible reactions between the aluminium tube and the product. The electrolyte conductivity should never be used as thesole criterion for quality evaluation of the internal coating, but always with other parameters e.g. film thickness, acetoneand/or ammonia resistance and of course results of enhanced stability studies.
