Abstract 

ISO 7326:2006 specifies five methods for determining the ozone resistance of the outer covers of hoses:

  • method 1, for bore sizes up to and including 25 mm, carried out on the hose itself;
  • method 2, for bore sizes greater than 25 mm, carried out on a test piece from the hose wall;
  • method 3, for bore sizes greater than 25 mm, carried out on a test piece from the cover;
  • method 4, for all bore sizes, carried out on the hose itself;
  • method 5, for all bore sizes, carried out on hoses that are expandable, for example textile-reinforced hoses.
