CSN EN ISO 7233

CSN EN ISO 7233 This document 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.
