Abstract

This Standard specifies five methods for determining the ozone resistance of the outer cover of hoses. <br>Method A : applicable to hose of 25 mm or under in inside diameter, and carried out on a hose-shape test piece <br>Method B : applicable to hose of over 25 mm in inside diameter, and carried out on a test piece sampled from hose <br>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 <br>Method D : carried out on a hose-shape test piece, regardless of inside diameter <br>Method E : applicable to expandable hose such as textile-reinforced, and carried out on a hose-shape test piece, regardless of inside diameter <br>NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. <br>ISO 7326 : 2006 <em>Rubber and plastics hoses - Assessment of ozone resistance under static conditions</em> (MOD) <br>In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and <strong>JIS</strong> are IDT (identical), MOD (modified), and NEQ (not equivalent) according to <strong>ISO/IEC Guide 21-1</strong>.
