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.
2 Normative references
The following Standards contain provisions which, through reference in this text, constitute provisions of this Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
