This document specifies five methods for determining the ozone resistance of the outer covers of hoses:<\/p>\n
method 1, for bore sizes up to and including 25 mm, carried out on the hose itself;<\/p>\n<\/li>\n
method 2, for bore sizes greater than 25 mm, carried out on a test piece from the hose wall;<\/p>\n<\/li>\n
method 3, for bore sizes greater than 25 mm, carried out on a test piece from the cover;<\/p>\n<\/li>\n
method 4, for all bore sizes, carried out on the hose itself;<\/p>\n<\/li>\n
method 5, for all bore sizes, carried out on hoses that are expandable, for example textile-reinforced hoses.<\/p>\n<\/li>\n<\/ul>\n
For hoses with built-in fittings from which it is not possible to take test pieces, the ozone resistance can be assessed on slabs in accordance with ISO 1431\u20111<\/span> <\/span>, using test sheets of the appropriate polymeric compound vulcanized to the same degree.<\/p>\n<\/div>\n Rubber and plastics hoses.
