适用范围：This International Standard specifies a method for determining the abrasion of a hose lining when a certain amount of specified grit is passed through the hose. The method is applicable to rubber and plastics hoses with an internal bore of 20 to 50 mm used for grit blasting, shot blasting and similar operations. The method may be used for comparison of the abrasion resistance of different types of hose, but not for specification of maximum abrasion in a hose standard. Comparison should be made on the same type and size of hose. Results from tests car-ried out with different types of grit should not be compared.
