This Standard specifies five methods for determining the ozone resistance of the outer cover of hoses.
Method A : applicable to hose of 25 mm or under in inside diameter, and carried out on a hose-shape test piece
Method B : applicable to hose of over 25 mm in inside diameter, and carried out on a test piece sampled from hose
Method C : applicable to hose of over 25 mm in inside diameter, and carried out on a test piece sampled from outer cover of hose
Method D : carried out on a hose-shape test piece, regardless of inside diameter
Method E : applicable to expandable hose such as textile-reinforced, and carried out on a hose-shape test piece, regardless of inside diameter
