COLD RESISTANCE
1. Hose shall have a capability of use down to -35 degrees P,
Hose shall have no apparent damage to cover, jacket or lining
when subjected to the following cold bending test:
A 50 foot length of dry hose is to be firmly coiled and
placed in a cold box at -35 degrees F. for a duration of
24 hours. Immediately after the removal of the hose from
the hose from the box, the hose should be uncoiled and
laided out by one operr.tor. Following this prooedure,
the hose shall not leak nor show any damage to any thread
