适用范围：This International Standard specifies two methods for assess-ing whether a rubber or plastics hose retains adequate flexibility at sub-ambient temperatures.Method A is applicable to non-collapsible hose with a bore size up to and including 25 mm. It measures the increase in stiff ness compared to the flexibility at a standard laboratory tempera-ture.Method B is a simpler, qualitative method suitable for control testing and is applicable to hose with a bore size up to and including 100 mm.
