ISO 7233:2006

Rubber and plastics hoses and hose assemblies — Determination of resistance to vacuum

ISO 7233:2006 specifies three methods for determining the resistance to vacuum of hoses and hose assemblies manufactured from plastic or rubber. Applicable dimensions of hoses for each method are as follows:

• method A — for hoses of nominal bore up to and including 80 mm;
• method B — for hoses of nominal bore greater than 80 mm;
• method C — for hoses of all dimensions.

Methods A and B can also be used to check the adhesion of the lining to the reinforcement (delamination) in a length of hard-wall hose or hose assembly.
