This International Standard specifies three methods for determining the resistance of plastic or rubber hoses and hose assemblies to vacuum. The applicable hose dimensions for each process are given below: Process A: for hoses with a nominal inner diameter up to and including 80 mm; Method B: for hoses with a nominal inner diameter over 80 mm; Method C: for all hose dimensions. Methods A and B can also be used to test the adhesion between the inner layer and the reinforcing element (layer delamination) in the length of a hose with a coil or a hose assembly.
