1. Apparatus for method A

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