This Standard specifies two methods for assessing whether a rubber or plastics hose retains adequate flexibility at sub-ambient temperatures.
Method A is applicable to non-collapsible hose with a nominal bore up to and including 25 mm. It measures the increase in stiffness compared to the flexibility at a standard laboratory temperature.
Method B is a simpler, qualitative method suitable for control testing and is applicable to hose with a nominal bore up to and including 100 mm.
